>Anything that's "death soon or guaranteed cancer later" levels of energetic won't be lasting centuries because physics. I don't know which "physics" you're referring to, but here are the half-lives of just the most common isotopes (out of OVER 100) released in Chernobyl. iodine-131: 8.04 days caesium-137: 30 years strontium-90: 29.12 years plutonium-241 (decays into Americium-241): 14.4 years Americium-241: 430 years Remember, these are HALF-LIFE numbers, meaning half the isotopes will still be radioactive after these time intervals.
