Hi, everyone! In this video I am going to tell you about radiopharmacy and other radioactive medicine.

[@jayman4566]

As a person who has had cancer 4 times in my life, it is very easy to be slightly more radioactive than your environment and the people around you. Between CT scans and radiation treatments, I am about 10% higher than most people are for Rads. They are very careful with treatments now. X-rays, CT Scsns, and blood tests are all carefully monitored . We suspect but can not prove that several places we lived had radon gas problems.

[@poloska9471]

Awe man… I’m real sorry to hear that. Glad you’re still with us and fighting it, you must be quite strong to have gone through it 4 times and live to tell about it. I hope you get to live cancer free from now on… a part of me does wonder whether surviving cancer 4 times gives one badass bragging rights though, kind of like a story told at parties and everyone is like “no way!” lol… I don’t want to find out but geez… I bet by the 4th time it gets old like “aw… this shit again? What a pain in the ass”.

I’m not sure what you mean. Are you saying you’re more radioactive than most people because of CT scans and radiotherapy that you underwent?

[@BackYardScience2000]

No. NileRed sold out and only posts dumb videos now. He's only in it for the money now. Hence why he stopped making good videos and only sells his products these days and shows off in short videos. If he should do a video with anyone, it should be with NurdRage as he still to this day makes great science videos that teach you something. Or many of the small science and radiation based KZbinrs out there. There are dozens these days because most of the big science tubers sold out and aren't teaching us anything anymore.

[@vaibhavhayaran]

@@BackYardScience2000 dont forget @codyslab

[@timb7085]

As someone who underwent such testing and radiation procedures, one important thing is that for the selective radiation exposure, the part of the body being directly exposed is very firmly secured to the table via some sort of formed brace - in my case, a formed plastic mesh that clamped my head to the table so I was unable to move. I had a special tube that I could breathe through during the approximately 10 minute treatment. It's quite an experience having this huge machine automatically moving around you while your head is essentially bolted to the table. And - yes - you do see small flashes of light as some pass through your eyes. Very weird experience - but, life saving.

[@debrainwasher]

Occasionally Dr. kgb. Valdimir Putin administers very effective radio-therapies too. As far as we know, he is used to use ²¹⁰Po. At least in the case of his patient Aleksander Litvinenko.

[@flashgordon3715]

It's really too bad. I feel Russia was starting to be cool. I thought, "What if this leads to fewer sanctions, and Russia becomes more a member of the global market. I don't know what made me think Putin would pursue my hopes.

[@WaffleStaffel]

I carried my Geiger counter to the VA hospital once. Someone hot from imaging stepped into the elevator and the counter started screaming. I had to quickly turn it off, but I don't think anyone knew what the sound meant.

[@SolarWebsite]

Excellent video! I work in radiology and nuclear medicine IT, and I have a basic working knowledge of how most modalities work. But this absolutely taught me stuff I didn't know!

[@ag135i]

Thanks for the invaluable information packed video and you also care for the financially weak patients that was very heart warming to see.

[@brotkannschimmelnwaskannst604]

Another highly educating. It's densly filled up with information and told me more about medical use of radoiaktivity then I ever saw before. I appreciate for all I learned about natural science in your videos. This is what's the internet was invented for. Thank you very much and please keep up with teaching us about the world we life in.

[@technovikingfan]

Wow. I really enjoy your channel and what impresses me most is your ability to speak such good English. I am Canadian, with only one language, and when I hear scientists like you speaking so well, it makes me really want to learn a new language myself. Keep up the great work man! Take care.

[@travishanson166]

When the nurse puts on the lead jumpsuit and busts out the case with the fancy vial straight out of a bond or mission impossible movie, you know a Geiger counter would be an acceptable investment to score free beers.

Banger of a video my man! 👍 You get access that most people don't even know about. You are a natural born teacher and a student.

I work with radio medicine in cancer and seeing that title gave me a bit of a chuckle. "Not a lot. We inject radioactive materials into humans hundreds of times a day."

[@bobdrooples]

Many thanks to those patients who let you observe their treatment.

[@MesoHunterYT]

Epic video! I always wanted to know more about oncology treatments

[@wernerviehhauser94]

Interesting, I didn't think this would be about F18 and PET, I was expecting Tc99m. A nice follow-up would be a video about proton beam cancer therapy and the development of carbon beam cancer therapy.

[@WinstonWalker-fc7ty]

Thank you so much for covering Gamma Knife and Lutetium 177 therapies! I’d love to see you do a video on proton therapy!

[@foolicooli]

[@MolexGamePlay]

It seems to me that Thoisoi has taken an interest in the radioactive elements, study and medicine later. I am not surprised though, it is an amazing field to study

[@MikkellTheImmortal]

I always enjoy your channel, l learn something new every video. Thanks for continuing to make content. When I think about how long I have been watching you I'm surprised how many things you have already covered, and, how much is still to come

[@nobodistribe6092]

Great video. I had a radioactive dye in an iv and they took the scan immediately and all my blood vessels were glowing from the inside. Then they waited like 45 minutes for all dye to go to my bones. That scan my entire skeleton was glowing. The dye must have a strong affinity for bone. I know flourine has an affinity for bone but I'm not sure what was used in the dye.

[@petevenuti7355]

My mom had those radium implants, think that's how my Head came to be 6x background? Or perhaps it was just the nuclear fallout from the tests back when I was still in the woom . How do I figure out the isotope without a biopsy?

"its supposed to be 4000" Thoisoi2: Comrerades is only measley 3.6 roentgen, have no fear

[@DeathMetalDerf]

I'm actually concerned about X-rays and other medical imaging. I've had a ton of x-rays over my life. The only bone in my body I've never broken is my sternum, and I've been going to the dentist a lot for implants and stuff...

[@cwtrain]

Why? I wouldn't be. You've probably picked up more radiation in your life just walking around or taking an airplane ride.

[@markshort9098]

I wouldn't be worried, modern x-ray machines use much lower doses than the old ones and there's already 4,000 to 10,000 radioactive disintegrations per second happening in the body normally so the body is already quiet good repairing any damage from radiation

[@MichaelKingsfordGray]

That means that you have broken all 6 bones in your inner ear.

[@Jabarri74]

Like bananas? The potassium will likely give you more rads than the xrays. Point is our bodies are made to survive a certain amount

[@wernerviehhauser94]

I would be much more concerned about WHY I had so many broken bones.

[@fburton8]

I wasn’t allowed to go near my horse for some hours after he had been injected with technetium-99 for scintigraphy (trying to diagnose whether a lameness was due to damage in bone or soft tissue).

My niece had thyroid cancer and they treated it by removing it and using radioactive medicine. She had to stay away from her husband and children for a while.

[@BobBarker-ky6fi]

A proper vet can diagnose from his experience by hand and examination the poor horse will now be radioactive his cells literally discintergating hope he makes it don't posion the poor horse he needs the right diet and exercise swimning etc

[@dienosorpo]

Lu - Dotatate molecular structure is extremely cool haha.

[@Sdnaurs]

Radionuclides are so promising for the treatment of cancers. All we need is to find carrier compounds that migrate to cancer cells in a very specific way and we can target cancers.

[@tonyquark493]

[@nebunu1force]

A question: how is it even possible that some parts of the linear accelerator machine became radioactive after gamma ray or electron irradiation? I thought only neutron radiation can turn something else radioactive. Very weird and very curious.

[@hotgluegunguy]

I was wondering the same. Would like an explanation for that.

[@SearinoxNavras]

Anything can turn things radioactive if it has enough energy. With neutrons it's easy because having no electrostatic repulsion but still strong nuclear force interaction they will readily stick to other nuclei, converting them into different isotopes, of which most are radioactive. But photons with enough energy, and also other particles, can hit an atomic nucleus hard enough to chip off parts of it, like say knock off a proton or neutron, converting them into a different isotope or element, of which many can be radioactive. I believe the threshold is at around 7 MeV of energy. You can think of it as the ultraviolet threshold for ionization, except it's the energy threshold for disintegration. The more energy the particle, the harder it hits, the more it will make things radioactive. Plutonium-239 for example, the isotope used in reactors and bombs, is so unstable that it can be broken apart with photons of little over 1 MeV of energy. The more stable the nucleus, the more energy you need to hit it with.

[@Ste_Brit]

I have one name for you regarding nuclear power. Galen windsor (or possibly Winsor). Either way, he basically made out radioactive material wasn’t dangerous. Now I’ve seen radiation sickness and heard the stories about it but that doesn’t explain how hiroshima is perfectly inhabitable nowadays and has been for decades 🤷🏻‍♂️

Pooter bug?

[@meercreate]

@@ferretyluv Therac 25. The machine had xray mode (high current, with target) and electron beam mode (low current, no target). The commands sent by the remote computer (which was the only sanity checking thing that kept high current, no target from being an operating mode) were sent out of sync, and as a result, the machine was set to operate at high current with no target, frying the patients with a strong electron beam.
