This is very interesting. The first time I have seen your videos. My father was at the first radioactive test, and lived in Hawaii for several years. He was also on a Navy ship all over, and in later years designed guidance systems for guided missiles. He lived into his 80's, and never got cancer.
When I was about 13, I would fly out of SF and typically go to Chicago before getting on the next flight. This was during the Vietnam war. The red-eye flights were quite interesting as it was still ok to smoke on the planes and most of the military returning from Vietnam would be taking hits of weed laced with opium and then blowing that into the pillows as a filter. At that time, the airline industry was also regulated and most of those flights were quite empty. That screaming kid wouldn't have been a problem for those folks as they typically just fell asleep from the opium laced weed.
Great video! I did the same thing with my 102. I had people freak out when I told them I go hunting for radioactive minerals, when I was in a uranium mine I got a dose just over a dental xray doing that but when I flew to Alaska I got readings averaging around 1.22 usvh, so I got the same dose flying to Alaska and back
@@RadioactiveDrew😂 PS: Aircraft windows often have a slight metallisation, bad for GPS signals. In German high speed trains (ICE's) there is no signal at all for the same reason. 👍
Epic camera work, Hawaii looks similar to some places on Australia's coastline even down to the climate... incredible. Those watch hands with the radium were a cool find.. for a second I thought it was actually some contaminated cigars which would of been pretty frightening lol.
Love the videos! Something I do wish you would’ve mentioned in the video is if TSA has ever had or did have a problem with you bringing the geiger counters on board or if they’ve asked questions.
They didn't care at all. But I also didn't announce it to them. All my equipment went through the x-ray with no problems. The dose rate on the Radiacode that went through the new 360 x-ray machine was pretty interesting.
I’ve always been curious on this subject and appreciate your detailed work and presentation. Personally I worked 36yrs in the oilfield. My work had me flying long distances constantly. Retired now and glad to say nothing glows in the dark.😀🤣
I have a friend who crews for Hawaiian - I was thinking of loaning him my cheap 'counter, but seeing your numbers I realize it's time to upgrade. When my mom's cat got thyroid treatment her apartment went up 4x for a month or so. Thank you!
Im totally amazed at how much radiation the atmosphere protects us from. You mentioned a spike could that have been to the amount of solar flares there has been
I work for an airline as an aircraft mechanic and have replaced the radar system a few times. It’s labeled as “radioactive material” and have always wondered how much radiation it produces and how much more it produces while being used. When we test it we aren’t allowed to stand anywhere near the nose up to 30ft while operating.
@@RadioactiveDrewyeah, I knew that, Just curious how much radiation it produces just sitting there. Also the floor tracks glow in the dark, not sure what they are made of, but always makes me think of your videos lol
Drew (stepping out of airliner in Hawaii): "Wow. It's a lot hotter here than in Montana..." 😄 Would be interesting to see levels on an over-the-pole flight to Europe. Thanks for sharing your cinematic photography of the beautiful scenery and the radiation levels from your vacation.
Former airline pilot here, who also is a nuclear energy nerd: - Anecdotally, I do hear more and more about skin cancer amongst pilots (6:20). I'm not sure on any data to support this, but more and more pilots are wisely using sunscreen up front to help against the UVA/UVB due to the higher risk category the job carries. I'm not sure what the flight attendant is referring to with "Screening" otherwise, we just use tinted shades to help our eyes in the bright sun. - I've taken my gmc-300 onboard when not working occasionally. I see between 300-600 cpm based on latitude and altitude.
I could only imagine that it would be true since the pilots as well as the flight crew deal with far higher levels of radiation far more often than anyone that is riding to get from point A to B. There has to be some kind of increase in the chances of getting it.
thank you Drew for your sharing and fun look at things, kinda makes ya wonder how "radioactive" old aircraft are that have been retired that are kept in Mojave CA ?
Well some of those aircraft have counter balances in the wings made with depleted uranium. I really want to visit some aircraft scrapyards and see what I find.
Great videos usual. I've carried my 102 on numerous flights and almost always see a significant dip in background just after takeoff. My assumption is that it's because you're far enough away from the ground to reduce terrestrial radiation, but still low enough to get atmospheric shielding from cosmic rays. Similarly, I've noticed that when I get on a boat with a reasonable depth of water underneath, background immediately goes down ... believe this is because the water is shielding the terrestrial radiation
Interesting, often wondered what the altitude dose was. Have you been on the tour of the Nevada test site? Worth the trip if they are still doing them. I did it a bunch of years back along with Hanford and Trinity. Always wanted to visit the uranium mines in the 4 corners area but never did.
I think the lower background radiation has something to do with the atmosphere being slightly thicker towards the equator as well thus lowering it a bit on top of the islands being so old as you said.
That could be an explanation. The only thing that could throw a wrench in that idea is when I put a detector in a lead shielded area. The biggest drop happens when I block the ground and not the sky.
Drew where i used to live in a small town on the coast of Qld, the dialy count was around 15 to 26 with occasional spikes up to 30 or 40 cpm. In brisbane, ive been data logging for about 5 years now and my average is between 30 to 40 cpm
As one who has chased Northern Lights for the last couple of solar maximums, I have often wondered just how much more elevated amounts of radiation I'm absorbing during those events. If I can hear power lines crackling directly overhead, I'm sure levels must be off the charts. Plan a trip to someplace with good NL and treat yourself and us to some more info! Thanks!
Nope, since you're on ground level even standing beneath Aurora Borealis isn't an increase in radiation, at least not in any significant way. (It's less than negligible) If you were in a plane high in the atmosphere near the North or South south poles during a geomagnetic storm, then yes, but otherwise no. The crackling you hear is most likely due to electromagnetic interference or increased ionization which can also be weather related.
Like @Mr.Fox.92 said, the radiation doesn't increase on the ground during auroras. I didn't see any uptick in the ones we had over the summer here in Montana.
Great video, a neighbour of mine was an air hostess back in the 80s and when she retired she died of leukaemia, i think she was like 60 yrs old. I think you've scratched upon a cover up by the airlines not wanting to call out the dangers of large numbers of prolonged flights. Just on your format I'd probably tweak it a bit by doing a little sit down overview of your findings at the end of each flight, this ties together your partial comments. If you want to get real tech you could time link your radiation readings in your comments so people can go straight to them. The souvenir shop was great, you can add a comment with each article high reading like possible radiation in clay or paint, then move on to next. Make it a bit kindergarten for people that can't focus 100% in your video. Youll be smashing over 100k subs soon and traveling around the world to all the hot spots 👍
@RadioactiveDrew here's a few questions How much detail are staff briefed on the safety of radiation. Do airlines build in protection to the hulls, does the protection vary where you sit or for staff? Do budget airlines have less protection Is there a balance on protection and costs in extra weight Are different flights around the globe higher in flight radiation. Why is this. Does the ozone thickness reflect on radiation levels in flights
It wasn't really picking up on isotopes...it was more a mix of gamma energies. But the peaks kind of looked like some of the peaks for Thorium 232...a double peak. I believe it was more spread out.
Great video! I wish I had my radiation detectors when I flew on business before I retired. I’m certain there have been studies on the effect of radiation on flight crews, and I wonder if it shows the hormesis effect of radiation exposure to elevated levels that are not dangerous.
Cool video as they always are. The pilots that HAVE to wear dosimeter badges when they get to the cockpit, they'll removed the badge. Seal it into a water tight bag and insert that bag in a drink bottle. Water is a great blocker of radiation, 2cm of water blocks all BETA and the plastic of the water bottle already stops the Alpha. (I know you know but for your viewers :) ) My dad served on the USS Missouri late 70's till 86. Met my mother on shore leave here in Hobart Australia in 85* I'm the result of said meeting haha. Now that boats in Hawaii and I'd be interested if you do the tour, and are in and around the base. If you pick up any radiation around the area on better still on the BB63 Missouri :) (prob already left Hawaii but hope you see this)
Drew... with your good relationship with the DOE, maybe you can get a guided tour of the Nevada Test Site and they'll let you bring your monitors?? I did the standard public tour and they forbid it. 😭
It would have been interesting if you could show us readings while passing next to those baggage scanning machines at the airport, just to see if there's any radiation escaping.
Nah 60 minutes australia went there a few years ago, nothing crazy. Ive been yo a lot of the oacific islands off australia and nothing worth taking a meter for.
Koolau is Ko - O - La - oo . . . each vowel basically gets pronounced, so two O's are not one sound but two separate, where each get sounded. La - oo may get smoothed out by those saying this a lot. . .they will smooth it and not halt but make this like one syllable.
I usually set the first alarm to .5 uSv/hr and the second to 10 uSv/hr. Here where you can get the case I was using www.etsy.com/ca/listing/1709978516/radiacode-101-102-103-g-tpu-bump-case?ref=share_v4_lx&variation0=4500438465
Radeye should be energy compensated with gamma filter on. However, it catches a lot of muons with almost 100% efficiency, which affects the readings. Also, radiacode only measures radiation up to 3 MeV, it skips (doesn’t take into account) the part above that. So both radeye and radiacode are kind of wrong about doserate during flight. Radiacode measures only part of it, geiger counter catches photons of high energy but not calibrated for such conditions.
That’s true…I do have the gamma filter but I didn’t bring it with me for the trip. It doesn’t do automatic energy compensation. You have to set the isotope you want to have energy compensation for.
I like cold weather, one of the reasons I live in Montana. I like not dealing with bugs or getting sweaty for more than half the year. Summer in Montana can get pretty buggy and hot.
I’m working on a radon video. It’s an involved video that’s going to have a couple interviews with people. Really looking forward to getting that out. It’s going to ruffle some feathers.
@@RadioactiveDrewI think I know exactly *why* it's gonna ruffle some feathers. My guess is that radon dangers in households are generally grossly exaggerated and fear mongered. But we'll see :)
I'm looking forward to the radon video. I purchased an Airthings Wave Plus and have a 30 day average Radon reading of 9.7 pCi/L. I hope I learn enough about the radon topic with your video. Thanks for your videos, they're informative to say the least.
@@dornierGP should be a fun video. I already have a bunch of stuff shot at the Free Enterprise Radon Health Mine. I bought one of those Corentium Pro units from AirThings. Was the only radon monitor that I could find that would go up high enough to do my tests.
Why? It looks like the rest of NM to me, other than the obelisk marking ground zero and the stubs of the towers still remaining it looks like the rest of the Tularosa Basin desert.
Drew Runor has it that these drones in New Jersey might be radioactive sniffers and that background radiation in NYC is running higher than normal. They were reporting counts of 200+ ( I forget the units)
This is the issue, would you like K40 or Sr90. Is this a contact dose or internal ingestion and transit through body. Radium watch or radium paint brush tip. Galen Winsor a fun watch
I flew cross country during the massive solar storm last May. I wish I had a radiation detector with me for the trip. We hit the peak flying over Utah and Idaho. The entire sky was lit up.
I'm currently at 11:00 ... PLEASE tell me you're going to Enewetak Atoll. That place is just a tad hotter ... especially the sarcophagus full of radioactive sand that's leaking and now hotter on the outside. Looking at the giant craters in the atoll on Maps/Google Earth is impressive itself. The US sure committed some serious ecoterrorism in the 1950s. Probably make good fishin' 'oles but ...
I took a gq meter on a 14 hour+ flight from brisbane to Lima peru, brisbane to sydney, sydney to auckland nz, nz to chile aouth america and chile to Lima Peru. from what i could tell, not much diference. One thing that suprised me was the airport security were all aware of geiger counters and unfazed thankfully. If i win the lotto, il buy one of these beaut little loggers. Id love to log our next trip next year and back. I wish i had it with me for our wrong way round trip, we wanted to avoid chile and the usa, so flew to osaka japan, to paris, paris to Amsterdam, then panama to lima... wont ever go that way again, im thinking next time via hawaii and the us might be better?
I wonder what the dose rate is in the Business jets that typically fly at 41-45 thousand feet. Commercial airline pilots fly around 900 hours/year. So at a 181 micro rem/hour that would be around 163 millirem/year if my math is right. A typical Nuclear worker is allowed around 5 Rem/year. So pretty small dose.
I think there isn’t much of a difference. The increase in radiation comes from space and maybe some bleed over from the Van Allen radiation belts. They are really far out so they might not have any impact.
I have tested coral my father brought home from operation hardtack in 1958 from the lagoon of eniwetok island in the marshal islands and found no radiation. He was there for 23 of the blasts. Can you tell me exactly what type of Geiger counter you are using?
In the video I’m using a Thermo Scientific Radeye B20 and a Radiacode 103G. Well the coral would be protected under the water from neutron radiation, and all the other types. Neutrons can make normal objects radioactive by changing atoms into radioactive isotopes.
I tried this with my GQ GMC-500 plus in my shirt pocket and forgot to turn off the speaker. Before we got to 10,000' the alarm was beeping. It was the factory default setting.
I brought my radiacode on a 13 hour flight overnight and found that the radiation seemed to match the sun day/night. The altitude was nearly constant on the whole flight, but the dose rate varied to be I believe higher when it was brighter outside. I'm curious if that either means there is some sort of filtering that changes due to the atmosphere, or if some of it is also from the sun. Does anyone know why that may be?
You know, I remember I asked a question on reddit once about TSA confiscating radioactive antiques. You replied and instead of answering it you were just a real a hole. And here you are talking about the same thing I asked about. Imagine that.
I think I recall the radiation levels start to taper off as you approach the equator. This is due to the earths magnetic field deflecting cosmic radiation. Likewise cosmic radiation is higher than normal if you fly over the north / south poles.
You are going to get more radiation exposure the higher up you go...but at the poles it might be higher. I'll have to check next time I find myself on an overseas flight.
@ probably from something like lead foil or a hydrogen-rich shielding such as polyethylene or a combination of both. In aircraft like bombers and other VIP aircraft they are also shielded from EMP/EMF as well.
So many of the pilots I follow wear sun screen in the cockpit because of the solar radiation. Obviously it doesn’t stop the gamma etc but yeah I’d be concerned if I flew many times a week at 40,000+ ft.
@@RadioactiveDrew From Anne M Stark on the Lawrence Livermore web site, "Carbon-14 is produced in the stratosphere by nuclear reactions of atmospheric nitrogen with thermal neutrons produced naturally by cosmic rays (with the highest production rate 10 to 13 miles above Earth’s poles), as well as by atmospheric nuclear weapons testing in the 1950s and ‘60s." This C14 combines with oxygen to make carbon 14 dioxide then drifts down to ground level and is incorporated in plants. I was mistaken about ozone, however. It's produced, mostly at high altitude, by UV in solar radiation.
Drew, enjoy your approach to things radioactive. Not sure if you follow Dan Hurd prospecting on TH-cam, in a recent video (link below) he unearthed some of what he calls "thunder eggs". I thought they were just of interest because when cut and polished they have interesting insides (like geodes). However he showed the interior under black light and the interior lights up with all sorts of colors. Dan lives in BC so it might be interesting to see what kind of radiation those "thunder eggs" emit. th-cam.com/video/JOUG8j3Jvdo/w-d-xo.htmlsi=IA2Jwf7pWZ6SOzyf
I watch Dan Hurd's channel and I might have seen the video you are talking about. Those thunder eggs might not have anything radioactive in them. Plenty of minerals glow under UV light. Still, I'll look into it because I'm always surprised by new things.
Spend some time at the mile-high Denver Airport. Look at the longtime residents of Denver and see how much actinic keratosis (radiation skin damage) they have. They get a lot more pre-cancer skin damage than most people because they lack a mile of air to protect them from cosmic rays.
Gamma radiation from cosmic rays is going to give a whole body dose, not just concentrated at your skin. What exposes your skin by far the most radiation (UV) is just the big nuclear fireball in the sky, the sun. By far the biggest exposure to UV, and pre-cancerous skin damage is having light skin, and living near the equator. I had a boss who's parents were missionaries, and grew up in Madagascar. At 50+ he had some pre-cancerous skin legions, and had photodynamic therapy to prevent them from becoming cancerous.
Again...youre speaking of two different types of exposure. In an airplane, this is external exposure. You dont ingest any actual particles that can become trapped in the body. Using a device on an airplane or at the atomic bomb testing site is still external exposure. You can't calculate ones internal dose using dose rate on a detector. There is Derived Air Concentrations, biological halflife of the radionuclide, age, sex....so many other factors you couldnt know by making a video and taking a measurement.
All these various releases of effluents from reactors, fuel processing and reprocessing, contamination from waste storage and radionuclides in soil samples are being ingested and taken up into the body. It's in our food, water, air we breath or absorbed into the skin. Making the assumption that people are mostly exposed externally is not being honest. The fact is, the way that dose is calculated especially internal is proven to be false. The ICRP knows this, the NRC definetly knows this and our National laboratories know this to be true. Effective and equivalent dose uses a tissue averaging instead of the genotoxicity to DNA that causes damage even at low doses that you aren't properly explaining and trying to make the comparison of a flight on an airplane of external exposure versus what we are exposed to on the surface with both external and internal exposures. You are definetly incorrect about this Drew and should know it.
Thing is when I press on your comment to respond, it doesn't allow me to do so. If you seen my comment then you know there is nothing in it that would keep it from posting due to TH-cam.

Really cool tnx for sharing, i just wonder what elements you picked up on Radiacode on high flight levels?
It wasn't really picking up on isotopes...it was more a mix of gamma energies. But the peaks kind of looked like some of the peaks for Thorium 232...a double peak. I believe it was more spread out.

Drew... with your good relationship with the DOE, maybe you can get a guided tour of the Nevada Test Site and they'll let you bring your monitors?? I did the standard public tour and they forbid it. 😭
It is pretty common to get a rain shower early in the afternoon in Hawaii
The last day we were there some rain blowed in. Wasn't that bad since we were in the pool area.
It would have been interesting if you could show us readings while passing next to those baggage scanning machines at the airport, just to see if there's any radiation escaping.
Oh there was some leakage going on for sure. But nothing like what its like being right in the x-ray beam.
When I saw you were going to an island and checking radiation, I was hoping for Rongelap or Bikini...hahaha
Nah 60 minutes australia went there a few years ago, nothing crazy. Ive been yo a lot of the oacific islands off australia and nothing worth taking a meter for.
Koolau is Ko - O - La - oo . . . each vowel basically gets pronounced, so two O's are not one sound but two separate, where each get sounded. La - oo may get smoothed out by those saying this a lot. . .they will smooth it and not halt but make this like one syllable.
I figured I was still butchering it.
I’m curious what alarm levels you usually set on your Radicode 102.
The yellow case you have on yours looks like a good one.
I usually set the first alarm to .5 uSv/hr and the second to 10 uSv/hr. Here where you can get the case I was using www.etsy.com/ca/listing/1709978516/radiacode-101-102-103-g-tpu-bump-case?ref=share_v4_lx&variation0=4500438465
Doesn't the faa get solar reports from noaa? I follow Dr. Tamitja Skov, and she always reports on the status of radiation for flying.
Radeye should be energy compensated with gamma filter on. However, it catches a lot of muons with almost 100% efficiency, which affects the readings. Also, radiacode only measures radiation up to 3 MeV, it skips (doesn’t take into account) the part above that. So both radeye and radiacode are kind of wrong about doserate during flight. Radiacode measures only part of it, geiger counter catches photons of high energy but not calibrated for such conditions.
That’s true…I do have the gamma filter but I didn’t bring it with me for the trip. It doesn’t do automatic energy compensation. You have to set the isotope you want to have energy compensation for.
Gamma rays with energies above 3 MeV contribute a small fraction (likely
Good video.
Never been on an aircraft before, looks crowded at times.
It would be interesting to see the Radicode on Enewetak Atoll and on the Runit Dome
I agree. Hopefully I can make that happen.
You like the colder weather or you tolerate and are accustomed to cold weather ? LoL 😂😂😂
I like cold weather, one of the reasons I live in Montana. I like not dealing with bugs or getting sweaty for more than half the year. Summer in Montana can get pretty buggy and hot.
Maybe the low background is due to high atmospheric water content. Better cosmic shield.
Or, its just as you say, paradise on earth.
great stuff Drew now on to the RADON in basement videos please ?
I’m working on a radon video. It’s an involved video that’s going to have a couple interviews with people. Really looking forward to getting that out. It’s going to ruffle some feathers.
@@RadioactiveDrewI think I know exactly *why* it's gonna ruffle some feathers.
My guess is that radon dangers in households are generally grossly exaggerated and fear mongered. But we'll see :)
I'm looking forward to the radon video. I purchased an Airthings Wave Plus and have a 30 day average Radon reading of 9.7 pCi/L. I hope I learn enough about the radon topic with your video. Thanks for your videos, they're informative to say the least.
@@dornierGP should be a fun video. I already have a bunch of stuff shot at the Free Enterprise Radon Health Mine. I bought one of those Corentium Pro units from AirThings. Was the only radon monitor that I could find that would go up high enough to do my tests.
Always wondered about Latitude changes.
Another great video, I have been to ground zero of the Trinity Test Site a few times and it is always a surreal feeling.
It's on my list. I did the Nevada Test Site this spring and that was crazy. Walking out on Frenchman Flat was unreal.
Why? It looks like the rest of NM to me, other than the obelisk marking ground zero and the stubs of the towers still remaining it looks like the rest of the Tularosa Basin desert.
@@buckhorncortezbecause it’s a historical site…
Drew Runor has it that these drones in New Jersey might be radioactive sniffers and that background radiation in NYC is running higher than normal. They were reporting counts of 200+ ( I forget the units)
Yeah, I think that's total BS. The government already has helicopters with extremely sensitive detectors on them flying the city.
@ thanks 👍🏻
This is the issue, would you like K40 or Sr90. Is this a contact dose or internal ingestion and transit through body. Radium watch or radium paint brush tip. Galen Winsor a fun watch
I flew cross country during the massive solar storm last May. I wish I had a radiation detector with me for the trip. We hit the peak flying over Utah and Idaho. The entire sky was lit up.
"We used to have those radiation badges."

Please more videos about flying and cancer risk
I'm sure I will.
**Should have just driven** 😂
If I could have driven I would have.
Put it in the window, it goes up more. Even the window shade plastic is noticeable
I was there in July. We stayed in the townhouse’s across the empty field from Disney. Sounded like the natives were restless every night😂😂😂😂
老哥终于更新视频了
I'm currently at 11:00 ... PLEASE tell me you're going to Enewetak Atoll. That place is just a tad hotter ... especially the sarcophagus full of radioactive sand that's leaking and now hotter on the outside. Looking at the giant craters in the atoll on Maps/Google Earth is impressive itself. The US sure committed some serious ecoterrorism in the 1950s. Probably make good fishin' 'oles but ...
Very few people know this but there is a beach with green thorium sand that is quite radioactive.
I took a gq meter on a 14 hour+ flight from brisbane to Lima peru, brisbane to sydney, sydney to auckland nz, nz to chile aouth america and chile to Lima Peru. from what i could tell, not much diference. One thing that suprised me was the airport security were all aware of geiger counters and unfazed thankfully. If i win the lotto, il buy one of these beaut little loggers. Id love to log our next trip next year and back. I wish i had it with me for our wrong way round trip, we wanted to avoid chile and the usa, so flew to osaka japan, to paris, paris to Amsterdam, then panama to lima... wont ever go that way again, im thinking next time via hawaii and the us might be better?
Drew, have you ever been to the “Kreosan English” channel on you tube?
I have, really liked some of their videos. The one with the X-ray tube was pretty interesting.
I wonder what the dose rate is in the Business jets that typically fly at 41-45 thousand feet. Commercial airline pilots fly around 900 hours/year. So at a 181 micro rem/hour that would be around 163 millirem/year if my math is right. A typical Nuclear worker is allowed around 5 Rem/year. So pretty small dose.
Counts at high noon vs. counts at midnight? How much difference does solar radiation make?
I think there isn’t much of a difference. The increase in radiation comes from space and maybe some bleed over from the Van Allen radiation belts. They are really far out so they might not have any impact.
Did you save any gamma spectra during the flight?
Was there much of a difference flying at night vs. the day?
I have tested coral my father brought home from operation hardtack in 1958 from the lagoon of eniwetok island in the marshal islands and found no radiation. He was there for 23 of the blasts. Can you tell me exactly what type of Geiger counter you are using?
In the video I’m using a Thermo Scientific Radeye B20 and a Radiacode 103G. Well the coral would be protected under the water from neutron radiation, and all the other types. Neutrons can make normal objects radioactive by changing atoms into radioactive isotopes.
Hpge and lead shield will show trace
It would be interesting to see what it's like over the mid Atlantic anomaly from south America to Europe
I tried this with my GQ GMC-500 plus in my shirt pocket and forgot to turn off the speaker. Before we got to 10,000' the alarm was beeping. It was the factory default setting.
Yeah, I made sure to have all my dose rate alarms turned off.
I brought my radiacode on a 13 hour flight overnight and found that the radiation seemed to match the sun day/night. The altitude was nearly constant on the whole flight, but the dose rate varied to be I believe higher when it was brighter outside. I'm curious if that either means there is some sort of filtering that changes due to the atmosphere, or if some of it is also from the sun. Does anyone know why that may be?
What's the definition of background level being used here?
You know, I remember I asked a question on reddit once about TSA confiscating radioactive antiques. You replied and instead of answering it you were just a real a hole. And here you are talking about the same thing I asked about. Imagine that.
I think I recall the radiation levels start to taper off as you approach the equator. This is due to the earths magnetic field deflecting cosmic radiation. Likewise cosmic radiation is higher than normal if you fly over the north / south poles.
I had the same thought. Would be interesting to see radiation levels on an over-the-pole flight to Europe.
You are going to get more radiation exposure the higher up you go...but at the poles it might be higher. I'll have to check next time I find myself on an overseas flight.
They could easily reduce the radiation intake on flights. They do it in military aircraft and others such as Air Force One.
How
@ probably from something like lead foil or a hydrogen-rich shielding such as polyethylene or a combination of both. In aircraft like bombers and other VIP aircraft they are also shielded from EMP/EMF as well.
The hull already shields against some of the radiation. There's no way to completely block it on an aircraft.
So many of the pilots I follow wear sun screen in the cockpit because of the solar radiation. Obviously it doesn’t stop the gamma etc but yeah I’d be concerned if I flew many times a week at 40,000+ ft.
I bet the UV radiation gets super intense the higher you get.
@ I guarantee it does. Another good topic maybe for an interview is the dosage of rad the astronauts get on the space station.
Much cosmic ray energy is absorbed at high altitude turning nitrogen to carbon 14 and diatomic oxygen to ozone.
That’s a good question. I feel like someone would have written a paper about that process.
@@RadioactiveDrew From Anne M Stark on the Lawrence Livermore web site, "Carbon-14 is produced in the stratosphere by nuclear reactions of atmospheric nitrogen with thermal neutrons produced naturally by cosmic rays (with the highest production rate 10 to 13 miles above Earth’s poles), as well as by atmospheric nuclear weapons testing in the 1950s and ‘60s." This C14 combines with oxygen to make carbon 14 dioxide then drifts down to ground level and is incorporated in plants.
I was mistaken about ozone, however. It's produced, mostly at high altitude, by UV in solar radiation.
I think the sea water absorbs a lot of radiation too.
Only if you’re under the water. Above the water it doesn’t have any effect on the cosmic radiation.
🤘🤠🤘
Next a trip to Bikini Atoll? 😀
I really want to go there.
Drew, enjoy your approach to things radioactive.
Not sure if you follow Dan Hurd prospecting on TH-cam, in a recent video (link below) he unearthed some of what he calls "thunder eggs". I thought they were just of interest because when cut and polished they have interesting insides (like geodes). However he showed the interior under black light and the interior lights up with all sorts of colors. Dan lives in BC so it might be interesting to see what kind of radiation those "thunder eggs" emit.
th-cam.com/video/JOUG8j3Jvdo/w-d-xo.htmlsi=IA2Jwf7pWZ6SOzyf
I watch Dan Hurd's channel and I might have seen the video you are talking about. Those thunder eggs might not have anything radioactive in them. Plenty of minerals glow under UV light. Still, I'll look into it because I'm always surprised by new things.
@@RadioactiveDrew Looking forward to anything you find out!
@mickmccard it’s always to hear that. I try and make the videos interesting.

Motion X was killed back in 2020
Was it? Still works for me. I use it all the time. So far all the iOS updates haven’t killed it yet.
(Edit: whoops, my bad...)No visit to Trinity?
The visit to Trinity is at the end of the video.
Spend some time at the mile-high Denver Airport. Look at the longtime residents of Denver and see how much actinic keratosis (radiation skin damage) they have. They get a lot more pre-cancer skin damage than most people because they lack a mile of air to protect them from cosmic rays.
I think it’s more about the UV damage from the sun is much higher because of the slightly thinner atmosphere.
Gamma radiation from cosmic rays is going to give a whole body dose, not just concentrated at your skin. What exposes your skin by far the most radiation (UV) is just the big nuclear fireball in the sky, the sun.
By far the biggest exposure to UV, and pre-cancerous skin damage is having light skin, and living near the equator. I had a boss who's parents were missionaries, and grew up in Madagascar. At 50+ he had some pre-cancerous skin legions, and had photodynamic therapy to prevent them from becoming cancerous.
Do you eat uranium for breakfast ?
I try not to...
When the stewardess mentions skin cancer cases, was she referring to coworkers?
I think she was referring to the pilots...at least that's what I got from the conversation.
@@RadioactiveDrew Ah, gotcha. Interesting! Thank you again for another informative video!
Again...youre speaking of two different types of exposure. In an airplane, this is external exposure. You dont ingest any actual particles that can become trapped in the body. Using a device on an airplane or at the atomic bomb testing site is still external exposure. You can't calculate ones internal dose using dose rate on a detector. There is Derived Air Concentrations, biological halflife of the radionuclide, age, sex....so many other factors you couldnt know by making a video and taking a measurement.
The vast majority of people are exposed to external dose, so it makes much more sense to talk about that than any other source.
All these various releases of effluents from reactors, fuel processing and reprocessing, contamination from waste storage and radionuclides in soil samples are being ingested and taken up into the body. It's in our food, water, air we breath or absorbed into the skin. Making the assumption that people are mostly exposed externally is not being honest. The fact is, the way that dose is calculated especially internal is proven to be false. The ICRP knows this, the NRC definetly knows this and our National laboratories know this to be true. Effective and equivalent dose uses a tissue averaging instead of the genotoxicity to DNA that causes damage even at low doses that you aren't properly explaining and trying to make the comparison of a flight on an airplane of external exposure versus what we are exposed to on the surface with both external and internal exposures. You are definetly incorrect about this Drew and should know it.
You play some games with your comment section. I can't even respond to your comment? What type of nonsense is this?
Talk to TH-cam about it…I saw your last response and this one.
Thing is when I press on your comment to respond, it doesn't allow me to do so. If you seen my comment then you know there is nothing in it that would keep it from posting due to TH-cam.

I like hats, keeps the top of my head from getting sunburned.
@@RadioactiveDrew just observing!
Radiation is not the primary concern. The hazards come from the particles emitting the radiation. Hold your breath and don't drink the water.
No, this is from radiation…not from radioactive particles.
Sounded more like a democrat than a kid ….
Hawaii? How about Chernobyl. You're in Bzn! Hln here.
The destination has no impact on background radiation, only the duration of the flight influences the final overall dose.
@@PeopleThatFallApart Not talking about flights but thanks.
When things hopefully cool down with Russia I would love to check out Chernobyl.
@@RadioactiveDrew take me with you! I'm in Helena !~
Hawaii is newer land mass than the main land that probably why background radiation is lower .
