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?
They should make you the official English voice over for Russian scientists in movies!
Excellent explanation as always
Totally agree 👍
This series on metals is so cool
So informative and easy to understand, easily one of me favorite science series in RUclips
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 👌
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 channel is among the best for Chemistry! Thank you for all you do
You worked hard for 2 years to make this video so we the viewers give you 2K likes in 7 hours.
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 😂😂
This was an absolutely fascinating look into the radio medicine aspect. Thanks for making that possible!
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.
This accent is a perfect fit for chemistry :) Love this guy!!!
The Brits be like: hold my gin!!!
The efforts.. to explain about an element..
A big thank you, dear thoisoi, your accent is beautiful!!
Great episode, very interesting and educative. Thank you!
PS. I hope the patient is well.
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 !
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.
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
This was truly fascinating. Brilliant video, sir. Thank you so much!
This channel is pure gold.
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.
Amazing video! Hard to find info about Technetium, this was definitely the most thorough!
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.
@@Name-js5uq
Beat me to it
This video was so helpful to every thing i needed to research!
I of course linked your channel on my presentation! Keep it up!
ive had 4 of those scans over the years never new it was technetium
Very good video! Thank you for all your hard work and research to help share this with us all!
Thanks for your hard work to teach us something.
Probably the most Lovable scientist ive ever seen or heard. 😄
That was very interesting and informative. Two thumbs up.
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.
Very exciting video of a rare element! Thank for the excellent effort.
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.
Was waiting for this
Love your videos and channel. Keep your accent, it’s very distinguished. English or Russian, you are a great professor. I always learn a great deal from your videos and channel.
Man, if I have had these knowledge sources when I was a teen... You are awesome!
How about weakest man-made metal on earth chinesium ?
Chineesium is not an element but a complex compound. Its composition is held secret by the chineese but rumors say that it mostly consists of small pieces of alluminium foil from used chocolate bar wraps and ground and compressed rice husk bound together with a liberal amount of polyputyourkettleon glue.
My mother was an oncology (cancer) nurse for over a decade. I was lucky enough that the doctors she worked for were very kind and I was allowed to learn so much about different types of treatments, including radiotherapy. And to be honest, I think a lot of the patients liked having a kid around to talk with. When my mom was first starting out she was in nursing homes and I loved going there before school, watching Power Rangers, and being doted on by the sweet old ladies, lol...
That Periodic table on the wall is awesome
Very good video, seriously for to learn as documentary, i find very it really interest!
Interesting, Thankyou, for teaching myself something it did not know. Again, Thankyou.
Namaste 🙏 💟
You're an it?
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.
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!
I got treating with this in the hospital to test my gul bladder. I lay on on the table with the film on either side of me. was a very interesting experience
*gall
Love that pte with actual elements.
👍 thumbs up on the video and in the comments also, thanks for the informative video.
I am inclined to embrace the information provided due to the factual evebts and image of Ma[suriam]100.
I saw atomic weight labeld as 99 and 97... in other sources.
I like your accent, the reference of Euros, the image of table in Engkiah and high production quality.
Thank you for sharing your contribution
You might want to blur out or even cut the video footage showing him entering the keypad code for security reasons. Awesome video
Science is beautiful.
Many thanks.
You make chemistry accessible for many people
Is really cool that the hospital and the patient let you film and show you how they prep for a scan. I had a similar scan done many years ago, but they used gallium instead.
Just depends on what they are looking for….
I'm not sure they knew what they were looking for. It was just one thing in list of tests about as long as my arm.
Great videos sir. I learn more in 15 minutes than weeks of watching TV.
It's called 'programming' for a reason.
Estonia! what an intresting contry - i say intresting because there is little that i know about it exept for it's brief history
Does anyone know title of the background music that starts at 0:00 ? I've been searching for the title for ages :C Its so futuristic, I can't get enough of it
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.
That is a nicely done video, thank you.
Excellent video. Thanks for sharing!
That technetium generator was probably made in Poland, in Polatom facility near only one existing nuclear reactor in Poland, "Maria" reactor in Świerk, near Warsaw.
Great! Thanks for this subject!
I liked how he hired Borat for dubbing .
That is him doing his own dubbing. He records the video in Russian and does the voice over in English for this channel.
This could have been the reason those who lived near such water resources had body structures different than other areas.
This was a great video. I appreciate the extra effort that you did in getting the hospital footage to explain its usage.
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?
Very interesting, informative and worthwhile video. Very well-done video.
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.
So, southing your original voice is. I love your videos and hope you return to this voice. Double watching this is way better than the new video voice. Please bring this one back who ever told you to change it was out of their mind 😊
Wow, thank you dude, that was really interesting.
You are a legend. In youtube chemistry at least
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.
This has been the coolest video i've watched this month. I love radioactive isotopes and geiger muller counters!
Excellent videos! Thank you for your hard work making them 🙂
That was really cool that you got a couple people to allow you to measure their radioactivity. It must’ve been hard to keep a straight face when seeing how much radiation they were emitting! 😳
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.

Fossil fuels saved whales from extinction.
Pandas exist only because of Humans; they were meant to go extinct.
The Ozone Hole is a naturally occurring phenomenon visualized via statistical satellite data smoothing (do I bother mentioning torus' and diamagnetism to you?).
Polar bears thrive with less North Polar sea ice.
Humans have created far more species than we have eliminated.
God damn misanthrope...
Thoisoi2, you might want to cut out the part in the video were you show the guy typing in the passcode to the hospital @ 9:10.
Thank you so much
*Maria Skłodowska-Curie (not Maria Curie)
I've had 3 scans in 4 years for my heart.........it has to be made the same day. Amazing technology!
I love your channel
Max: radioactivity
Captions (cc): over the activity
Good video though do more
Those are RUclips's autocaptions, so why are you implying Thoisoi is to blame for them?
Heyyy sry if u found it offensive but im trying to show how funny the RUclips's captions are
Thank you for all your work :)
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.
Great video!

You can't wear it as a hat.
I hope the hospital rotates their security codes. Love your work. Been watching for 7 years
Literally I think I smoke too much because I swear I've never seen this video before it but then I found a comment I left here four months ago
I LOVE YOUR VIDEOS!!! I have learned SOOOO MUCH that I would have otherwise never had to chance to explore. THANK YOU!!
Amazing video kudos for efford to record test and get permissions just for it
lol I was sooo confused @ 11:07 - I thought you said it "needs to be diluted in regular CYANIDE " !!! lol - I understand now that you were saying "SALINE" - I'm just used to hearing it said with an American accent and it sounding like "say-leen" - :)
What an amazing guy ! Thank you.
Thanks for the video. It is very interesting and very illustrative for the general knowledge of people who do not know about these issues.
Long time no see!!
Finally an amazing video again👍🏻👍🏻
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.
Bro that 6:25 moment when he said the same sentence twice made me question reality
شكرا جزيلا على هذا الفيديو لم أكن أعلم ذلك !
Thank You SO MUCH for Teaching! 🙏🚂🎼🌹🎶🎵⚕🕊
this was brilliant. many thanks!
Funny, i just had a thyroid scan a few days a go with injected technetium, no side effects what so ever.
Thanks for video
Highly informative video, probably the best in that field, although i am strongly opposed to the injection of radioactive material into a body in any medicinal context including tomography.
Interesting to see the radiation safety in other countries using Tc-99m. Their finger doses must be so high.
