I love how Thoisoi despite being Russian, would put in the extra effort into informing us in English too.
Probably part of the reason he has so many subscribers to be honest.
I definitely appreciate the extra effort
In theory he could just provide subtitles on his original channel (which has more than twice the amount of subscribers by the way) but i guess most english speaking people wouldn't be interested in the videos then
The question is though, is it actually him speaking English? I've seen him speaking Russian, albeit only once, and he sounds completely different, not even close.
And although I know that many people who aren't very good with other languages tend to put an exaggerated voice similar to when someone tries to copy an accent for the first time I don't think that's it either, the English might not be the best but it's also not bad either, so I'm wondering if he has someone to do the actual translations for him? 🤷
@@DoctaOsiris It is him, the difference in voice in his newer videos may come from the different mics being used (original sound russian, english dub)... If you watch some of his older videos and compare the languages you will surely notice that it is one person speaking (edit: also the voice of a person sometimes sounds slightly different when they speak a foreign language)
Great video. As a radiologist, I’d like to add a couple additional points of interest. First, there are only two reactors in the world that produce Mo-99, the parent of Tc-99m, and which only has a 1/2 life of 66 hours. These are located in Ontario and the Netherlands (there may be a third in South Africa, but I’m not sure). So when one of these reactors goes off line, the result is a worldwide shortage of this important medical radionuclide.
Another point is, with the exception of thyroid imaging, pertechnetate is not used by itself for imaging. Rather, it is chemically bonded or chelated to organic molecules designed to target different organs. These are the workhorses of nuclear imaging and include Tc labelled tracers for imaging everything from the heart to bone to kidneys to gallbladder.
Last, what makes Tc99m such an ideal radionuclide for imaging is not only its short T1/2, as was mentioned, but also the fact that it produces, for practical purposes, gamma rays of only a single energy, 140 Kev, which happens to be the the same energy where modern gamma cameras are most sensitive. Also it produces no beta or alpha radiation, which would add no imaging information, but could be harmful to patients.
Based technetium.
Probably could drive to the plant in Ontario cause I live there
That is so interesting! I've considered studying Radiology at a few different times in my life but I always have something else going on. Gotta take a chance one of these days and go for it..
did u know technetium means crafted element?
This series on metals is so cool
So informative and easy to understand, easily one of me favorite science series in TH-cam
Tahike 😂😂
Does anybody know if someone could harness this beta radiation and power an electronic device
This guy taught me about sulfur dioxide and silver... never keep a silver coin in your back pocket
@@dustinswatsons9150 that was my first thought as well.
@@vernonvouga5869 any way to look into that
You always deliver. 👍👍
100% information
0% bull
Lovely accent 👌
They should make you the official English voice over for Russian scientists in movies!
Excellent explanation as always
Totally agree 👍
Thank you for covering this element. This was the metal that was used when I went into radiation therapy for my left eye. Very interesting.
I hope you are well now :)
@@trapdoorguppi thank you for your well wishes. I have most of the vision in my eye back. The tumor was benign thankfully.
@@jonhu4127 congratulations! Cool to hear that the uses are so noticeable
Im a simple man, if I'm watching Thoisoi i'm happy
This accent is a perfect fit for chemistry :) Love this guy!!!
The Brits be like: hold my gin!!!
Thank you! One of my friends underwent a procedure where technetium was used and we wondered how the hospital could get it when it has such a short half-life.
Some hospitals may have molybdenum “cows” on site that they can use….. or they have to provide orders to a nuclear pharmacy in the area where they get the Tc-99m. I worked in such a nuclear pharmacy while in pharmacy school. The nuclear pharmacy accounts for the decay rate when they prepare the injection
@@erikawanner7355 Thank you.
I had something as well a decade ago. For checking my lungs. I was kinda worried as I saw a metal syringe. The moment where watching horror films has gotten a revenge xD
You worked hard for 2 years to make this video so we the viewers give you 2K likes in 7 hours.
This channel is among the best for Chemistry! Thank you for all you do
The efforts.. to explain about an element..
A big thank you, dear thoisoi, your accent is beautiful!!
So educational: I learned that the capital of Estonia is Tallinn! (oh yes, and something about metals too :-) )
Yeah but you have to say Tallinn very slowly.
I actually happened to know that. But, I see a lot of people are saying that Thiosoi is Russian. I could be wrong, but, when he started talking about Tallinn, I first thought he must be Estonian.
@@NiceMuslimLady
I don't think I've ever heard his native voice. Afaik no way to prove he's Russian.
It's 69 likes and I'm going to ruin it 😂😂😂
Done 😂😂
My father did this same tomography last month, in a very similar machine. I didn't knew they used radioactive medicine. Very interesting, thank you for the video!
If he didn’t get an injection of radioactivity, then it might had been some other kind of tomography, such as CT or MR.
The following options are available:
* Gamma radiation, usually Tc. Can be planar images or reconstructed into 3D volumes (SPECT)
* Positron radiation (PET). Better but extremely expensive as the isotopes must be produced in cyclotrons.
* MR : Magnetic coils in the machine.
* CT: X-ray tube in the machine
MR and CT do not need anything injected to the body. It is optional to use non radioactive substances.
@@magnushem8734 interesting information, thanks. I don't remember many details, but I know he did receive an injection 4 hours before the exam, but I didn't receive any information about what was that.
I wonder if a 1kg ingot of that would put out so many electrons that it had a blue corona discharge around it. Or if you could use that for a "nuclear battery".
If it did, I'm sure Jeff Bezos would use it as a night light.
Nah its quantum yield is too low. Better stick to strontium 90 or plutonium 238. It would probably be warm to the touch though. (Note: do not touch ingots of radioactive isotopes lol)
@@SocialDownclimber yeah I've heard horror stories of skin peeling off like bad chemical burns or needing to get fingers removed due to tumors on them, I'll pass.
Probably the most Lovable scientist ive ever seen or heard. 😄
Few years ago, my mother went for such a medical procedure. Later, we had to cross the US border, but she forgot to inform the custom officers of this. You should have seen all these armed guards coming from everywhere when their radiation sensor flagged our car. It took us a little while to understand what was going on. In retrospect, it was almost hilarious.
This is the first and only time I have ever seen the 'Moly Cow' process in action, and I can't thank you enough for showing it. It's always fascinated me how they can now just make a radioisotope for medical imaging right there in the hospital lab instead of depending on a few specialized reactors to have a supply. Awesome, and so is Technetium. A metal so unstable there is none of it around in nature smack in the middle of the periodic table instead of the extreme trans-actinides.
I had a bone scan using this technique, but the nurse used a shielded syringe for her own safety, and I had to wait four hours for the bones to absorb the medium. It was good to see how the medium is produced, thank you.
This was an absolutely fascinating look into the radio medicine aspect. Thanks for making that possible!
This was a great video. I appreciate the extra effort that you did in getting the hospital footage to explain its usage.
My wife had a procedure with technetium and would set off my radiation detector even if she was in an adjacent room.. lasted almost two days, not just 24 hours..
Great video, learned quite a lot..
Tc-99m has a half-life of ~6 hrs so it should be a background around a day but if a detector is very sensitive it may still pick it up
@@erikawanner7355 doesnt half life mean that 50 % of material decays ,and then 50%from that 50% decays and so on ?
@@dodoslovensko Indeed.
You should be commended for your accurate and informative summary of Tc, the generalization of its properties and role in modern medicine. You took a relatively complex subject and made it comprehendible for the average person.
As an aside…I’m an American Pharmacist. Early in my career, I practiced nuclear pharmacy for a short while.
I LOVE YOUR VIDEOS!!! I have learned SOOOO MUCH that I would have otherwise never had to chance to explore. THANK YOU!!
This has been the coolest video i've watched this month. I love radioactive isotopes and geiger muller counters!
My wife had a stress test a few months ago and I had my Geiger counter with me in her hospital room. The test showed she was free of blockages, but when she entered her room my GC went crazy. The room was large and the readings were high even across the room and also from inside the bathroom. Before the background was 0.12 micro sieverts per hour, but when she got back from her test it was around 400 micro sieverts per hour with the GC on her body. 48 hours later it was greatly reduced but still above background.
Thank you for taking us along on such a neat journey!
the door code is visible at the Nukleaarmedtsiin room, you should notify them to change the code
Yes, I thought that too! Please up vote above comment so that hopefully it is noticed and acted upon. Thanks!
This channel is pure gold.
Hey there ! I am a fan of yours since the channel started, every day I start by watching Thoisoi2.
I always recommend it to all of my students and they all like your channel as well ! :-)
Anyway !
Должен сказать...ЭТО деиствительно одно из твоих уникальних видео !
Импрессиве материал !
Relevant to me, I remember this procedure from years ago - with gratitude. Highly memorable was a huge metal-clad syringe and the look on the technicians face as he weilded it. Its content was probably expensive. An interesting follow up would be to discuss the decay chain, i.e. the elements that technetium decays into, their half life, toxicity and how the body removes them - given that lead Pb tends to accumulate.
Technetium 99m decays into Technetium 99. Technetium 99 has a huge half life, so whatever stays in you will be mostly there when you die. The quantity is so low that you wouldn't see any biological effects from the chemistry unless you got a 100x overdose, and then the radiation would probs kill you first.Good question though.
Hello from the United States!! Not going to lie, I find your videos very informative and entertaining. Keep up the good work. 😀
So, by your statement it is implied that you normally do lie but in this instance you're not going to.

Beat me to it
I've had 3 scans in 4 years for my heart.........it has to be made the same day. Amazing technology!
Great video, thank you for taking the time to create it.
Thanks so much for this awesome and informative video! The direct view of the doctor sampling and dosing that cancer medication to that patient was really interesting to see. Great job on the video!
I had this radioactive tomographic imaging test done recently but never knew much about the medicine they gave me. Thanks for explaining the science of this amazing element!
A P.E.T scan?
Excellent videos! Thank you for your hard work making them 🙂
Still heavily enjoy your voice all these years watching your channel, thank you for doing this
Great episode, very interesting and educative. Thank you!
PS. I hope the patient is well.
ive had 4 of those scans over the years never new it was technetium
This video was so helpful to every thing i needed to research!
I of course linked your channel on my presentation! Keep it up!
Great videos sir. I learn more in 15 minutes than weeks of watching TV.
It's called 'programming' for a reason.
This was truly fascinating. Brilliant video, sir. Thank you so much!
I've had a bone scan with Tc99m. The level of detail is astounding, and it's a little unnerving when you realise YOU are the gamma source. You're right about it being flushed quickly as even during the scans your bladder looks like a lightbulb.
There was some confusion with the unusual density of the bones in my arms and shoulders, as I wrecked my knee almost a decade ago (nerve damage sucks) and use crutches to get around. This explains my profile picture with my brother (it was a private joke), also why I'm wearing bike mitts indoors...
The facilities at Guy's hospital, London were impressive even the staff don't know how many scanners they have (I used 3-4). Similar to an MRI (1 CAT scan), it gets pretty gruelling going from one to the next and being clamped down.
I've requested my medical records (not for fun), hopefully the images are included. If they are I'll send them to you if you like? Also, let me know if you're ever visiting London. It is a teaching hospital and I have some contacts.
Very good video! Thank you for all your hard work and research to help share this with us all!
Thank you for all your work :)
Discovered this channel last week, binging since. Love it, great job to the content creator of this channel.
The sad side effect of binging- finishing all the videos in a short time. I have 120+ channels subbed, most only upload once a month or two. Pain in the ass when I'm bored 😜😜😂
Great video and description. TY for showing us 👍
Wow, thank you dude, that was really interesting.
That was very interesting and informative. Two thumbs up.
Great video mate! Nicely done.
this was brilliant. many thanks!
Fantastic video! Your work is going better and better everytime.
I love your work. The video's you make are like candy to me! Thanks!
Amazing video! Hard to find info about Technetium, this was definitely the most thorough!
I hope the hospital rotates their security codes. Love your work. Been watching for 7 years
Thank you for your content! Always fantastic!
Science is beautiful.
Excellent video. Thanks for sharing!
Long time no see!!
Finally an amazing video again👍🏻👍🏻
Very exciting video of a rare element! Thank for the excellent effort.
That's really interesting. I had no idea Technetium had any real-world uses. Also 👍 for the English version!
The most I knew was what I read about it some time back...like it was just a "proof of existence". There are some other radioactive elements that they haven't found a use for...yet. But, then, I think it's Americium that is used in smoke detectors.
Thanks for the video. It is very interesting and very illustrative for the general knowledge of people who do not know about these issues.
Fascinating! Thanks!
Great! Thanks for this subject!
Fascinating, thank you!
Fantastic documentary, and thank you for the English audio too. Liked and subbed.
That is a nicely done video, thank you.
Thank you so much
Great video! Interesting as always :) Love your little trip to the hospital and with cool music too :)
You just got to love this channel. Do your thing, that's why I keep coming back every time!
Oh hey would showing us different types of radiation made visible with a self made vapor chamber be something for this cannel? This is such a cool experiment.
Wow, thanks for such an amazing video!
Я благодарен за ваши усилия по просвещению и обучению нас.
Another very interesting and wonderful video. Thank you!
Oh man, I just saw how many videos English speakers are missing from your main channel, but now I'm just thankful that you are doing so many in English for us already! :)
Thank you so much!! Very interesting video
Thank you for the video, that took a lot of work and perseverance.
Fascinating video thank you.
Thanks for your hard work to teach us something.
Many thanks.
You make chemistry accessible for many people
Keep pumping out great content
I learned about Technetium when I referred by a cardiologist to have a myocardial perfusion stress test of my heart. From the internet I learned about the Technetium solution that was injected into me was called Technetium(99mTc) sestamibi. So I am also one of the many persons who have been to the Nuclear Medicine department of a Medical Center where this radioactive isotope was used to measure the blood flow to my heart muscle.
Incredible video like always 🙏🏽
Man, if I have had these knowledge sources when I was a teen... You are awesome!
An amazing video, Thank you! :)
Excellent Video! Very Informative!
Thanks. You do a fine job. 👍
Well done, very interesting. Thank you, the hospital staff and the patients.
Hospital staff? You mean murdering agents of the State?
No one has ever died at home from the Kung Flu. Keep that in mind at all times
@@Vicus_of_Utrecht Interesting approach. At least we'd have to thank them for their covert solution to the earth's overpopulation then.
@@Vicus_of_Utrecht I seriously can’t tell if you’re joking, and that saddens me.

Humans have created far more species than we have eliminated.

Once, I had a Technetium injection and got clear instructions from the Doctor on how to behave in the following 24 hours. E.g. sit but not stand while peeing to prevent radioactive splashing!
