Hi Lilly, Just looked at the specs for the Fellat geiger counter, I think the problem is that the dose rate it can measure at maxes out at 10mSv/hour, this means that although it can display a total dose over time of 10Sv this would likely be grossly wrong in the event of a 'major nuclear incident'. Hypothetically the dose per hour could be 500mSv/hour or greater, but the machine would only be recording at 10mSv/hour! (the max capability of its GM tube before it is saturated). Therefore, before the machine displays a total dose of 1Sv you would actually have been exposed to many times this amount. Check out a second hand Polish RS70 or British Plessey/Siemens PDRM82 as these were designed to warn of dangerously high radiation levels, I believe the Plessey/Siemens PDRM82 was also EMP hardened (at least to some extent!). For new devices I think the Nukalert keyring device sounds impressive and there is also the Ecotest Terra-p+ - although prices have increased dramatically. All the best and thanks for the great videos!
How the keto diet is going? Have you considered going carnivore for 1-3 months ? Excellent elimination diet , after that go keto again if you feel best with some plants.
Hello Lilly, some days ago you made a video about your medical condition. "Low Carb" can help you. I learned a lot about that from Dr. Sten Ekberg (YT).
I appreciate how thoroughly you test your equipment, Lilly. If I were planning to buy any sort of expensive electronics, I would definitely check your videos before making a purchase.
Thank you for this follow-up video, Lilly. Very nice! I literally would have absolutely no clue what to look for in a Geiger counter, or how to test one. You are the one I rely on for information on many things. Keep up the excellent work!
As a retired Rad worker for the US gov. I would say that any high lvl picked up by the meter is concern for leaving the area and to distance ur self from the source. The actual lvl detected isn't going to mean anything other than time to leave. Unless u have proper shielding, distance from source of explosion, and minimum exposure to radiation ur not going to survive. Chernobyl was a prime example as well as the nuclear power plant in Japan. Wide spread contamination from a source not even part of a conventional explosive device. AS the winds blew and the ground water flowed so did the contamination. And if u pick up a high lvl what do u do? Knowing is not everything.
I think some of the people replying to your well thought and articulated comment are not understanding. To them, I say: A meter that measures high levels of radiation is unnecessary, as it means you are dead if your cheaper geiger counter is maxing out for any significant period of time. For lower levels of radiation, such as the hobbyist, the meters that measure high levels of radiation serve no purpose.
Well if you have a bunker and you can get away from the radiation in close proximity it could help. I mean if your Bill Gates and have bunkers at all your houses
Thanks for these excellent, practical reviews. On the basis of your testing I ordered a model 950, which I think will meet my needs. And congratulations on an excellent channel, as well.
Even if the user does not fully understand the readings, as only a relative, or precise measurement of exposure, these dosi-meters will provide much needed emotional assurance that one is located in the most protected part of a shelter. A dosi-meter should also be used to gauge one's exposure should they need to leave the shelter for a short period of time to perform an essential task, and to examine the person for radioactive debris that they may have inadvertently carried back to the shelter. Always use PPE(Tyvek suits and a respirator), or strip off spare clothing and scrub if necessary. And these meters can be used to determine when, and for how long persons can safely leave the shelter for several hours as the intensity of fallout diminishes, and when they must only sleep in the shelter in the later stages of the event.
If there was fallout, these cheap Geigers will saturate and the readings drop to zero! I visited a friend in hospital who had had technetium for a gamma camera scan and my Geiger counter (a professional one, not a toy) went crazy and then just stopped until I moved away from the bed. The current drawn for the avalanche of pulses drops the voltage across the geiger tube and the tube ceases to respond. You need to use an ionisation counter like the civil defence people use.
At min 13:10 you are talking about it can measure 10Sv and the other device cannot. 10Sv is just the accumulation of the measures over time or I´m I wrong? But 10mSv/h is still quite some radiation.
Hey Lilly I have been following your channel now for a couple years and just want you to know that what you did for "JOE x is a real stand up thing to do.. I always liked your personality but now I also Like your Heart!!!! God Bless you and your family Lilly Marry Christmas
In Canada we have Dollar stores which are a great supply of cheap but effective tools and gear. Usually under $5. Axes, saws, rope, tape harnesses, straps, knives, food, batteries, lots of everything cheap, even medical supplies.
I also have the Pudibei NR-750. It's good for analyzing mushrooms, and such a clock. But when it comes to nukes, for that purpose I have bought a RADTriage50 card.
Ok Lily, you twisted my arm on this last text you did and I have bought one. I do take on board things you say, but convicting reports from one peeler to the other, we're it gets confused. With the tests you have proved it, so thank you for that. Take care all the best for the festive season.
Hi Lilly - I love your videos and am always interested in your very insightful "take" on things. Knowing that there are cheaper Geiger counters is great. I do think, for those interested, they may do even better in buying one from one of those military surplus establishments. The price would be cheaper, not to mention the older ones are less susceptible to any interferences which the newer, digital models might run into. I will be saving my money, however. I do not believe that the world is headed into any sort of nuclear exchange. No matter if I'm wrong or right, I live in New York City, anyhow - for whatever that may mean! MERRY CHRISTMAS and HAPPY NEW YEAR.
The Pudibei NR-750 & 950 both look good, but my main concern is if the nukes start flying and for any us lucky or unlucky enough to survive the blasts will need something reliable for detecting fallout radiation levels. For this purpose would you bother with the Pudibei or just skip them and take a chance on the Fellat?
Just got my NR-750 for 298 CNY, which is around 40 USD, I guess the price is bit lower for domestic online platform (JD, in this case), thank you for navigating through the cheaper Chinese made models for us since we all know different Chinese makers produce really good ones and bad ones at the same price tag.
Not true. Even if high range detectors are usually based on ionization chamber or solid state detectors, there are many geigers that goes up to 50, 100, 150, 200, 500 and even 1000 R/h The thing is.... you probably never find any high range only geiger counter because is easier to use a ionization chamber or a solid state detector instead..... But if you want a wide range detector (i.e. from background to nuclear catastrophe!), is most likely be a geiger counter equipped with 2, 3, 4 or even more geiger tubes (each one dedicated to measure a certain range only). A very easy example: an SV-500 (a surplus military geiger counter that prior to Fukushima was available for 65 euros) is able to measure any level from elevated normal background to 1000R using 3 different geiger tubes cointained into 2 different probes (that can be either inserted into the machine for local measurements or connected trough the provided cable for remote measurements). There are also 2 more extra probes available for this instruments (rare and quite expensive) to extend the measurement range into the normal background (either in air or submerged in liquids) and further extend the range into contamination search (alpa-beta-gamma-Xray, pancake probe..... very sensitive but of course not accurate). .... and, yes, this geiger is military grade: waterproof, shock proof, very sturdy (very heavy metal case, you can ride your car above it without damages!) and of course is already EMP proof
Also, an HFS-P3 is a radiation detector / dosimeter / alarm that is based on a geiger muller tube that goes up to 5R/h. And, BTW, is very tiny, is chinese made and is dirt cheap (can be found around 20 euros on aliexpress during sales)
Hi, I'm heading to fukushima in two months and need to buy a geiger counter for the trip. It's only going to be used for maybe a few days tops, which would you recommend with limited budget in mind
I am curious what brought you to this conclusion. I'm new to Geiger meters and would love to learn more. How do you know what kind of error it has? Is there some kind of mathematics formula or is it made to detect only CS137, or?
The differences between the three pudibei could very well be down to the placement of the geiger tube. It's just placed in there using sticky tape. I put stickers under mine (NR-1050) where the ends of the tube are so that I can place sources as optimal as possible. Have thought about moving the tube to perfect center as close to case as possible (nano tape is great and have thickness)
Have you considered the electrostatic on bag with watch maybe read different on each instrument? Because it will, given the degree of measurements you are using.
Nice work. Love your comparison testing and how you use a graph to compare them equally. Would really like to see you compare the EcoTest and GQ 500 meters as well.
In a nuclear radiation scenario it would be important to have at least two units. 1 for high radiation and one for the lower levels. If you approach an area of suspected radiation or just stick your arm out the door there are 2 potential problems. 1. If the radiation is high and you have a counter that only does low levels your counter can be overwhelmed to the point that it becomes totally useless for anything. 2. If you walk into an area with your low level counter it may be saturated where it is giving false reading levels to the point where you are already past the point of no return. You should start with your high level meter, if it shows a high level of radiation you need to stop and reevaluate the situation immediately. That might be to retreat back the way you came or return into the shelter you came out of to then try later or the next day. If your high level meter shows nothing or very little then you switch to the low level meter and start advancing into the target area. When the low level meter starts or shows radiation then you can more safely evaluate the situation without becoming contaminated past the point of no return for your body. The third thing to think about is if your meter is in a radiation situation how are you going to decontaminate it so that the meter survives the experience. Placing the meter in a well sealed plastic bag to start, double bagged would be better. Then if you do get a reading the outer bag can be removed outside your hot line, which should be in a safe place to begin with, the meter can proceed through the hot line to the end where the second bag can be removed so that the meter can live to fight another day. Thanks for the testing Lilly. Good luck in Austria.
My Aunt was over for dinner , she was in the living room and was wondering why she heard a woman's voice coming from my home office ,she watched a little bit and laugh, she said when the nuke scare was around in her day , the ginger counters looked like big flash lights weighed a few pounds and cost more than the ones you were testing
Do those Geiger meters also measure REM exposure or RAD accumulation? And remember that Radon (Rn) gas can build up in basements and might contribute to a higher reading.
Good job on comparing models, but all of these meters will be no good during a nuclear war. They don’t go high enough. These are fine is you want to check if your fruit is radioactive, but they’ll kill you during a nuclear war. Why? Because they’ll likely either read zero (from a saturated GM tube) or they’ll give you a reading far below the true level. There are two types of radiation meters you need for a nuclear war scenario: one is a Geiger counter and the other is a War Meter. War Meters can measure much higher levels, like you’ll see with nuclear fallout. BTW, that Fellat meter won’t read up to 10 Sv. It’s a typo.
Checking contamination in food has to be done with expensive lab equipment. If you detect above background in food or water it is too dangerous to eat or drink, but there can be dangerous levels you cannot detect with a hand held device. Ingesting and breathing radioactive isotopes is very dangerous, more than being near the isotope. Also contamination that is not right next to your detector, say inside an apple or a fish, may not register at all because of its distance but would still be dangerous to consume.
Great info, as most other prepper channels have gone to " daily news " as it is easy, lazy, and no prep or work and just reading and regergitating the daily news to get views = money ,,, this daily news is insulting, disapointing, and adds nothing to our skill share needs. Than you, You are still true to the skill share, the work, and the benifit we all need.. thank you
I used to make quite effective Dosimeter badges from black & White photographic paper and a thin steel penny washer. You cut the photographic paper to the size of the penny washer and stick the washer over the exposed area. The hole in the middle is your exposed control. When after use in a radioactive area, develop the paper and it will show small dots where a particle has passed through the washer and therefore also yourself.
A great review of the Pudibei NR series Geiger counters. I've got the NR-850 and has a M4011 GM tube installed dated 2022. Circuit board has J305 stamped on it, so it might have been originally designed for J305 tube. Apparently GM tubes have a limited life of 5-8 years?
They probably use more than one type. Whatever they have available. They probably also sort it out by quality and put the good ones in the red and blue one
Thank you Lilly! I have been shopping for a quality/inexpensive Geiger counter and your research has helped me make a decision. (NR 750) On a funny note I thought you said the brand was "Pewdie Pie" LOL! Take care!!
Thanks Lilly for this part2 , i could only get the nr850 at the time so was hoping it performed as the nr750. Good to know it does if not a little better also. Hopefully i will never get a reading above 2 msvts lol . Stay safe 👍
Lilly I got the NR750 thanks to you. Background here is anything between 0.1 and 0.17. Not having a suitable clock to test, after sleeping on it I decided to try a smoke detector. My son tells me they contain alpha radiation... Anyhow without opening it and a bit of experimenting, the 750 is reading up to 0.36! Very happy with that. Thanks for taking time to review these... ❤
awesome!! the NR750 can only detect beta and gamma radiation tough. so it probably picks up a bit of gamma radiation altough americium-241 should be an alpha emitter only. very interesting.
They only contain Am-241 if they're the ion type - not the optical types. These days the opticals are by far the most common (in Denmark at least). Opticals consist of an LED, a photo diode and a fancy housing which ensures diode can't see the flashed unless there's smoke (or heavy dust) in there. You can search online for "nano wand" zero point quantum scaler energy etc. Those "wands" contain thoriumdioxide and are great and safe (unless you carry it in a pocket everyday) test sources.
Mine is pretty close to the last one you had, I wish you would have trsted it just to see what it did, I have a tiny piece of low dose uranium sample that was tested by a lab and certified, got it off amazon as well
They used to use Radium as the glow material in watch hands. The women painting them on would often wet the brush with their mouths. They were known as "the Radium Girls."
You need to be careful with the difference between Sv and Sv/h the fellat is only specified to 10 mSv/h, similar to the other devices. It needs 1000 hours to get 10 Sv. I also don't think it is correct to compare different sensor sizes close to a point source when that is not what they are calibrated for. Higher value does not mean better.
Lilly, Thank you so much for your research into this frightening topic. It is indeed sad when the fate of mankind is in the hands of maniacs that would actually consider using such weapons. But, this is the world in which we live. I agree with your view that the best way to allay such fears is to learn, study and investigate ways to mitigate the risks. I have purchased the NR-750 due to the results of your research and comparison to your expensive unit. I only wish there had been an affiliate link with Amazon to help you a bit. Thanks for all you do and I wish you the very best!!
I have very bad news for you. In the 20's they used to make radioactive glass, products and toys.. because they thought it was good for health. Or just because it would glow in the dark.
Kann man die Knackgeräsche beim Pudibei Nr.850 beim Zählen von Micro Sievert pro Std ein und auschalten ? Danke Can you switch the cracking noise on and off on the Pudibei No. 850 when counting micro sieverts per hour? Thanks
I just got the NR-750 and caught another prepping channel reviewing and showing you how the use. He even referenced the prior review here. He did have a card with radiation information on it as to the different level readings. Trying to find that or the information. Anyone have a clue we’re to look?
The Canadian Prepper just made a video on Geiger counters and he explained the need for detecting Alpha and Beta. I looked into it and the Pudibei doesn't detect Alpha. Now I need a video comparing the cheapest Geiger counters that also detect Alpha.
Danke Lilly, ich hab schon öfter geschaut, aber die Preise haben einen doch etwas abgeschreckt, und bei den billigen war ich mir nicht sicher, wie gut die funktionieren. Hatte erst so ein diy Gerät im Blick, habe mir aber nun das 850er Modell bestellt. Ursprünglich wollte ich mir das zulegen um nach Fukushima die Kontamination von Fisch zu messen, was ich auch tun werde, aber angesichts der aktuellen Lage ist es auch nicht schlecht, so etwas rumliegen zu haben. Lieber haben und nicht brauchen, als brauchen und nicht haben. Und wir wissen alle, wie unsere Industrie tickt, sollten zb. Importierte Lebensmittel belastet sein, werden einfach die Grenzwerte erhöht. Wär nichts neues.
Hi @SurvivalLilly, have you had time to do more tests and a broader experience with the Fellat geiger counter? Have you tested it with stronger sources?
Another good review although I wondered about your enthusiasm for the Fellat device since it performed poorly at low levels of radiation and you seemed to just assume that it would work well at high levels. Given its cheap price and the poor performance of some of the other cheap devices I don’t think this is a safe assumption. Or did I miss something? :-)
👍 Great test vid. Thanks 😎. Last year I bought the Cloixon Nuklear Strahlungsdetektor from Amazon with integrated electr magn field detector. The el. field detector works. I tried it at my walls around switches and sockets . It seems to work. It detects electric cables in the wall. So you can test before drilling. But I don't know how the nuclear detector works. Could you please take an eye on it.
The gamma scout is also a cheap hobby meter! Professional ones start at 1000€ I would suggest to buy a second hand FAG or Ludlum or Thermo Fisher scientific!
Hi Lilly , i doubt you will even see this comment so late after you did the video. I did watch these when you 1st posted them . I have a SOEK's Nitrates tester (Ecotester2), its for testing food , BUT it also tests food for radiation . I was wondering if you had one as its a combined 2-in-1 Geiger Counter + Nitrate Tester so i'm keen to know if you could test one against your hot watch as i think it would be an interesting comparison . Thanks very much for your videos, i very much look forward to them. Much love from Australia 😊
Just watched this again (searching for which geiger to get next) and I think there's multiple flaws. The close up reading you really can't use for anything as even just a mm difference in distance from tube makes a huge difference and all have different distances from tube to casing. Much better is would be to know distance from tube to casing and then add whatever to make distance to tube 1cm. I have a compass with radium and 0,1mm from the tube it can read 40µS/h (both XR1 and NR-1050). Then the distance measurements. The max reading is not that interesting as decay is random and max depends on firmware interpreting it. Much better is taking the average. That can be difficult for some that don't have an avg function but then take accumulated over 30 min or so. 5min for those having avg it should be enough. The XR1 and Cajoe sure have its flaws but not as bad as you make them sound - they just not have the tubes up close to the casing. Then the one that you can't disassemble. Those reading are way off. Either it's defective or you've not found the location of the tube. A small tube sure MUST have the same (average) readings as large tubes - if not there's a (huge) calibration issue. Sieverts is a well defined unit and it doesn't depend on tube size - just like speed doesn't depend on wheel size. But sure it will have far less clicks than a large tube.
You should really test them all with two sources of different strengths. Not sure how you'd get another source - maybe several sets of watch hands (it's the radium in the luminescent paint that you're detecting)
Hi Lilly do you think your Govt. would be interested in setting a perimeter up, around cities where the winds blow in, with Geiger counters to warn your people when to stay inside, if a war should break out because you's would most likely not get a direct hit, but the out fall will hit you's from all directions, being so high up because humanity is going to need as many people as possible to survive... just a thought if it should happen in our life time... like outpost...
Hi Lilly, i like that Gamma Scout and your demonstration. I was wondering and i asked this of Nate too (Canadian Prepper), which of the Geiger counters are better? The Gamma Scout or the one Nate is selling the GammaGuard CT007-F. I think with the craziness happening in the world, it would be nice if you did a Part 3 on Geiger Counter effectiveness and which two are better. i would love to be able to afford both, but alas i can only choose one. Thanks so much for a great channel.
Awesome content Lily! You have no idea how many lives you "saved". Just wondering if you tried the BoSean FS5000? its supposedly same pricing as the Nr750? Thanks!

Hi, I'm heading to fukushima in two months and need to buy a geiger counter for the trip.
It's only going to be used for maybe a few days tops, which would you recommend with limited budget in mind
I am pretty sure the gamma scout reading is also wrong, calibration factor is for Cs137.
I am curious what brought you to this conclusion. I'm new to Geiger meters and would love to learn more. How do you know what kind of error it has? Is there some kind of mathematics formula or is it made to detect only CS137, or?
The differences between the three pudibei could very well be down to the placement of the geiger tube. It's just placed in there using sticky tape. I put stickers under mine (NR-1050) where the ends of the tube are so that I can place sources as optimal as possible. Have thought about moving the tube to perfect center as close to case as possible (nano tape is great and have thickness)
Have you considered the electrostatic on bag with watch maybe read different on each instrument? Because it will, given the degree of measurements you are using.
How about getting a FNIRSI GC-01 from Amazon to test on round 3?
Thanks Lily 🎄☃️🎄
good review Lilly, thank you
Nice work. Love your comparison testing and how you use a graph to compare them equally. Would really like to see you compare the EcoTest and GQ 500 meters as well.
Would the NR 850 be useful to test radiation in canned fish?
In a nuclear radiation scenario it would be important to have at least two units. 1 for high radiation and one for the lower levels.
If you approach an area of suspected radiation or just stick your arm out the door there are 2 potential problems. 1. If the radiation is high and you have a counter that only does low levels your counter can be overwhelmed to the point that it becomes totally useless for anything. 2. If you walk into an area with your low level counter it may be saturated where it is giving false reading levels to the point where you are already past the point of no return.
You should start with your high level meter, if it shows a high level of radiation you need to stop and reevaluate the situation immediately. That might be to retreat back the way you came or return into the shelter you came out of to then try later or the next day. If your high level meter shows nothing or very little then you switch to the low level meter and start advancing into the target area. When the low level meter starts or shows radiation then you can more safely evaluate the situation without becoming contaminated past the point of no return for your body.
The third thing to think about is if your meter is in a radiation situation how are you going to decontaminate it so that the meter survives the experience. Placing the meter in a well sealed plastic bag to start, double bagged would be better. Then if you do get a reading the outer bag can be removed outside your hot line, which should be in a safe place to begin with, the meter can proceed through the hot line to the end where the second bag can be removed so that the meter can live to fight another day.
Thanks for the testing Lilly. Good luck in Austria.
Very cool that the Cajoe Geiger counter (the last model) has a socket for the GM tube which allows it to be easily exchanged.
Good afternoon from Syracuse NY USA my friend and I hope ( pray) you are doing better.
fantastic, detailed work. thank you.
Appreciate the info, Lilly!
Thank you for sharing your knowledge. Have a Merry Christmas 🎅
Thanks, Lilly !
My Aunt was over for dinner , she was in the living room and was wondering why she heard a woman's voice coming from my home office ,she watched a little bit and laugh, she said when the nuke scare was around in her day , the ginger counters looked like big flash lights weighed a few pounds and cost more than the ones you were testing
It would be interesting to add to the comparison the test of the GQ GMC-800 model now very popular on Amazon
Do those Geiger meters also measure REM exposure or RAD accumulation? And remember that Radon (Rn) gas can build up in basements and might contribute to a higher reading.
Good job on comparing models, but all of these meters will be no good during a nuclear war. They don’t go high enough. These are fine is you want to check if your fruit is radioactive, but they’ll kill you during a nuclear war. Why? Because they’ll likely either read zero (from a saturated GM tube) or they’ll give you a reading far below the true level.
There are two types of radiation meters you need for a nuclear war scenario: one is a Geiger counter and the other is a War Meter. War Meters can measure much higher levels, like you’ll see with nuclear fallout.
BTW, that Fellat meter won’t read up to 10 Sv. It’s a typo.
Checking contamination in food has to be done with expensive lab equipment. If you detect above background in food or water it is too dangerous to eat or drink, but there can be dangerous levels you cannot detect with a hand held device. Ingesting and breathing radioactive isotopes is very dangerous, more than being near the isotope. Also contamination that is not right next to your detector, say inside an apple or a fish, may not register at all because of its distance but would still be dangerous to consume.
Great info, as most other prepper channels have gone to " daily news " as it is easy, lazy, and no prep or work and just reading and regergitating the daily news to get views = money ,,, this daily news is insulting, disapointing, and adds nothing to our skill share needs. Than you, You are still true to the skill share, the work, and the benifit we all need.. thank you
Great test.
So Lilly to be clear the one in part 1 is still the best of bunch? They sold out after your last review in the uk market.
Thank you very much, Lilly, this was really helpful for me!
I used to make quite effective Dosimeter badges from black & White photographic paper and a thin steel penny washer. You cut the photographic paper to the size of the penny washer and stick the washer over the exposed area. The hole in the middle is your exposed control.
When after use in a radioactive area, develop the paper and it will show small dots where a particle has passed through the washer and therefore also yourself.
Hi Lilly,
Thank you very much for all the reviews.
It is very helpful.
Cool channel, BTW.
Buy an old civil defense one .you dint have to have a digital screen.they are cheap and are more resistant to emp
How much are they?
A great review of the Pudibei NR series Geiger counters. I've got the NR-850 and has a M4011 GM tube installed dated 2022. Circuit board has J305 stamped on it, so it might have been originally designed for J305 tube. Apparently GM tubes have a limited life of 5-8 years?
They probably use more than one type. Whatever they have available. They probably also sort it out by quality and put the good ones in the red and blue one
the best counters to buy is the ones in the military that you can go at a military auction they sell for cheap and they last a very long time
Thank you Lilly! I have been shopping for a quality/inexpensive Geiger counter and your research has helped me make a decision. (NR 750) On a funny note I thought you said the brand was "Pewdie Pie" LOL! Take care!!
😂 I thought you said the brand was "Pewdie Pie" LOL!
I heard Pewdie pie aswell 😅
Thanks Lilly for this part2 , i could only get the nr850 at the time so was hoping it performed as the nr750. Good to know it does if not a little better also. Hopefully i will never get a reading above 2 msvts lol . Stay safe 👍
I have the 750 and 850 and both are excellent. Great review and test. Thanks
Very thorough reviews. I like reporting the various GM tubes. Thanks.
Great that you tested several counter from the same company.
It shows they are fairly consistent.
Lilly I got the NR750 thanks to you. Background here is anything between 0.1 and 0.17. Not having a suitable clock to test, after sleeping on it I decided to try a smoke detector. My son tells me they contain alpha radiation... Anyhow without opening it and a bit of experimenting, the 750 is reading up to 0.36! Very happy with that. Thanks for taking time to review these... ❤
awesome!! the NR750 can only detect beta and gamma radiation tough. so it probably picks up a bit of gamma radiation altough americium-241 should be an alpha emitter only. very interesting.
@@SurvivalLilly oh! I can't explain that lol! Either way it appears to have provided a reading. I'll record a short video and tag you in it... 😉
They only contain Am-241 if they're the ion type - not the optical types. These days the opticals are by far the most common (in Denmark at least). Opticals consist of an LED, a photo diode and a fancy housing which ensures diode can't see the flashed unless there's smoke (or heavy dust) in there.
You can search online for "nano wand" zero point quantum scaler energy etc. Those "wands" contain thoriumdioxide and are great and safe (unless you carry it in a pocket everyday) test sources.
Mine is pretty close to the last one you had, I wish you would have trsted it just to see what it did, I have a tiny piece of low dose uranium sample that was tested by a lab and certified, got it off amazon as well
Interesting Lilly good information
How do you get a radio active watch?not that I want one but curious 🤔. Lol
They used to use Radium as the glow material in watch hands. The women painting them on would often wet the brush with their mouths. They were known as "the Radium Girls."
Thank you for your work!
You need to be careful with the difference between Sv and Sv/h the fellat is only specified to 10 mSv/h, similar to the other devices. It needs 1000 hours to get 10 Sv.
I also don't think it is correct to compare different sensor sizes close to a point source when that is not what they are calibrated for.
Higher value does not mean better.
The data sheet probably cannot be trusted. But still I keep it, 10mSV is not too bad at all
Lilly, Thank you so much for your research into this frightening topic. It is indeed sad when the fate of mankind is in the hands of maniacs that would actually consider using such weapons. But, this is the world in which we live. I agree with your view that the best way to allay such fears is to learn, study and investigate ways to mitigate the risks. I have purchased the NR-750 due to the results of your research and comparison to your expensive unit. I only wish there had been an affiliate link with Amazon to help you a bit.
Thanks for all you do and I wish you the very best!!
Name one "maniac" who has used nuclear weapons. I'll wait.
@@zacklewis342 Harry Truman
She bought radioactive material at the "flee market". WHAT!
I have very bad news for you. In the 20's they used to make radioactive glass, products and toys.. because they thought it was good for health. Or just because it would glow in the dark.
Which of the three models is able to produce sound everytime it detects a particle?
Hello,
Which model would you use underneath a drone to measure radiation from leakage from a power plant?
Kann man die Knackgeräsche beim Pudibei Nr.850 beim Zählen von Micro Sievert pro Std ein und auschalten ? Danke
Can you switch the cracking noise on and off on the Pudibei No. 850 when counting micro sieverts per hour? Thanks
Hello Lilly... what do you think of the Mestek NCO3? .. could you review it .. thanks in advance
I just got the NR-750 and caught another prepping channel reviewing and showing you how the use. He even referenced the prior review here. He did have a card with radiation information on it as to the different level readings. Trying to find that or the information. Anyone have a clue we’re to look?
Could you tell me the name of this youtuber? I would like to check the card he showed
@@SurvivalLilly Peaceful Prepper. Someone had also asked him and he said it came with it sounded like another device.
The Canadian Prepper just made a video on Geiger counters and he explained the need for detecting Alpha and Beta. I looked into it and the Pudibei doesn't detect Alpha. Now I need a video comparing the cheapest Geiger counters that also detect Alpha.
Great video. I have Bosean 600. Hope its good cause I dont have anything to test it
I love the nr-950 I got thanks to your last video thanks Lilly
Hello
Oh no I live in the United States 😢
Kinda messed up I won something but don’t know what and the shipping was gonna be 100 bucks what’s up with that
I purchased the NR-950 after seeing this review. The unit is cheap, had flickering display and unable to change things in settings. Sent it back.
Danke Lilly, ich hab schon öfter geschaut, aber die Preise haben einen doch etwas abgeschreckt, und bei den billigen war ich mir nicht sicher, wie gut die funktionieren. Hatte erst so ein diy Gerät im Blick, habe mir aber nun das 850er Modell bestellt.
Ursprünglich wollte ich mir das zulegen um nach Fukushima die Kontamination von Fisch zu messen, was ich auch tun werde, aber angesichts der aktuellen Lage ist es auch nicht schlecht, so etwas rumliegen zu haben.
Lieber haben und nicht brauchen, als brauchen und nicht haben.
Und wir wissen alle, wie unsere Industrie tickt, sollten zb. Importierte Lebensmittel belastet sein, werden einfach die Grenzwerte erhöht.
Wär nichts neues.
Hi @SurvivalLilly, have you had time to do more tests and a broader experience with the Fellat geiger counter? Have you tested it with stronger sources?
Can you tell me, please where to get, or what kind of radioactive sources for testing these Geiger counters?
Another good review although I wondered about your enthusiasm for the Fellat device since it performed poorly at low levels of radiation and you seemed to just assume that it would work well at high levels. Given its cheap price and the poor performance of some of the other cheap devices I don’t think this is a safe assumption. Or did I miss something? :-)
I was looking for an affordable Geiger counter and thanks to you I got the 950. Thank you very much😊
👍 Great test vid. Thanks 😎. Last year I bought the Cloixon Nuklear Strahlungsdetektor from Amazon with integrated electr magn field detector. The el. field detector works. I tried it at my walls around switches and sockets . It seems to work. It detects electric cables in the wall. So you can test before drilling. But I don't know how the nuclear detector works. Could you please take an eye on it.
When will you be doing survival outdoors stuff agen ?
Buongiorno.. cosa ne pensi del Mestek NCO3?.. potresti recensirlo.. grazie anticipatamente
The gamma scout is also a cheap hobby meter! Professional ones start at 1000€ I would suggest to buy a second hand FAG or Ludlum or Thermo Fisher scientific!
Hi! What about NR-1050 ? Any tests till now?
Your videos are very useful, thank you! Please do a Gamma Scout vs. Fnirsi GC-01 comparison too.
Hi Lilly , i doubt you will even see this comment so late after you did the video. I did watch these when you 1st posted them . I have a SOEK's Nitrates tester (Ecotester2), its for testing food , BUT it also tests food for radiation . I was wondering if you had one as its a combined 2-in-1 Geiger Counter + Nitrate Tester so i'm keen to know if you could test one against your hot watch as i think it would be an interesting comparison .
Thanks very much for your videos, i very much look forward to them. Much love from Australia 😊
Just watched this again (searching for which geiger to get next) and I think there's multiple flaws. The close up reading you really can't use for anything as even just a mm difference in distance from tube makes a huge difference and all have different distances from tube to casing. Much better is would be to know distance from tube to casing and then add whatever to make distance to tube 1cm. I have a compass with radium and 0,1mm from the tube it can read 40µS/h (both XR1 and NR-1050). Then the distance measurements. The max reading is not that interesting as decay is random and max depends on firmware interpreting it. Much better is taking the average. That can be difficult for some that don't have an avg function but then take accumulated over 30 min or so. 5min for those having avg it should be enough. The XR1 and Cajoe sure have its flaws but not as bad as you make them sound - they just not have the tubes up close to the casing. Then the one that you can't disassemble. Those reading are way off. Either it's defective or you've not found the location of the tube. A small tube sure MUST have the same (average) readings as large tubes - if not there's a (huge) calibration issue. Sieverts is a well defined unit and it doesn't depend on tube size - just like speed doesn't depend on wheel size. But sure it will have far less clicks than a large tube.
Most scrap yards calibrated their counters with a Coleman silk lantern mantle
Please give the buying link for these Geiger counters from Amazon please
I'm saving up for a NukAlert keyring. It's about £250.
Cheers Lilly I know which one I would get if I need to buy one.
You should really test them all with two sources of different strengths. Not sure how you'd get another source - maybe several sets of watch hands (it's the radium in the luminescent paint that you're detecting)
Hi Lilly do you think your Govt. would be interested in setting a perimeter up, around cities where the winds blow in, with Geiger counters to warn your people when to stay inside, if a war should break out because you's would most likely not get a direct hit, but the out fall will hit you's from all directions, being so high up because humanity is going to need as many people as possible to survive... just a thought if it should happen in our life time... like outpost...
Hi Lilly, i like that Gamma Scout and your demonstration. I was wondering and i asked this of Nate too (Canadian Prepper), which of the Geiger counters are better? The Gamma Scout or the one Nate is selling the GammaGuard CT007-F. I think with the craziness happening in the world, it would be nice if you did a Part 3 on Geiger Counter effectiveness and which two are better. i would love to be able to afford both, but alas i can only choose one. Thanks so much for a great channel.
the 750 goes up to 1000 which is 1 Seavitt which is quite low would if be any good
Can you try Aranet Radiation unit?
May I recommend the UNI-T UT334A? It has a new, very sensitive GM tube (HH442), and it's a well known brand.
Awesome content Lily! You have no idea how many lives you "saved". Just wondering if you tried the BoSean FS5000? its supposedly same pricing as the Nr750? Thanks!
Youre the best Lily ❤
I love these comparisons ..... you do them well.....very thorough
