>Pray tell, how long do you expect to live, and many centuries is your definition of "going away over time"?
Anything that's "death soon or guaranteed cancer later" levels of energetic won't be lasting centuries because physics.
Centuries is infinitely faster than the myriad of substances that don't go anywhere unless we pick them up and move them. Browse the EPA's national priority list for examples.
Nuclear is no more of a environmental contamination hazard than any other similar scale human activity involving nasty stuff.

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.
Having shit magically go away by itself is such a massive plus.
Imagine how contaminated that part of the world would be if Chernobyl released equally dangerous (like remediation workers dying in the same amount of time) levels of thallium.
