Depends on the size of the block of plutonium. If it is big enough, he will get burned by the decay heat----but probably not by the radiation (alpha emitter). But this is not likely, since even a small amount of plutonium constitutes a critical mass, and other bad things would happen.
Arrest him. Then make him sit on some plutonium for a week. Let him go. Re-interview this asshole.
