Most of the radioactive material has probably decayed away now. I doubt his corpse would be giving off a lot of activity.

it's most likely still pretty radioactive, that stuff stays active for long time... (Marie Curie's corpse is still radioactive i heard, and she died 91 years ago)

At least the good thing was that they were not cremated. The fallout would have been bad.

Yeah it's definitely *still* radioactive, but I meant the worst of it would be gone by now.
The short half life stuff would have mostly decayed away but the longer half life stuff will be kicking off the lion's share of the radiation by now (which will be significantly less than it used to be).
