Question: How do people with radiation poisoning get cured? Transplants, strong medicine? Would they be able to be saved at all? How strong does radiation poisoning have to be for a doctor not to be able to do anything about it? What unit is radiation measured in?

That’s a very good question and it’s very difficult to answer. It depends on how much radiation you’re exposed to, and how.
I don’t know if you’ve heard about Litvinenko, the Russian man in London who swallowed only a few grams of Polonium and died not long after, and managed to contaminate a lot of London too!
But then there’s also the story about the Japanese man Tsutomu Yamaguchi who managed to survive 2 atomic bombs! He was in Hiroshima when the first bomb hit, on a business trip and managed to escape, and went back home to his wife and child in Nagasaki, where 3 days later the second bomb hit! What an unlucky man! But, he survived both blasts and lived a long life, dying at 93.
If you’re interested in radiation protection you should google both of these famous cases, they’re fascinating.
