Oh no, the halflife of most of those things in a reactor is measured in millions of years. Nasty things like plutonium are about 25,000, some of the other nasties like Caesium and Strontium are about 30.
yay, yr11 physics teacher would be proud :p |
I think the full time for absolute decay (I don't think there is in fact such a thing) would be measured in the thousands of years, but the really, really strong activity dissipates in only a few decades. Remember, a light that burns twice as bright lasts half as long. :p
Granted, even after Uranium has reached its half-life, it is still quite radioactive....it's just that the most significant decay occurs within the first few decades.
edit: mathematically.
But maths, I am probably wrong. I don't even know what the hell they had in Chernobyl. |
