I thought you were saying the polonium-210 in the ring was liable to have killed someone (sorry if I misunderstood you on that). My understanding is that a lethal dose is a microgram, that only about a hundred micrograms are produced annually worldwide, and that a lethal dose is incredibly expensive if you can’t make it yourself in a nuclear reactor.
Okay, my mistake. But is it really at all likely that this ring ever had a toxic amount in it? Was just a lot more made in the 1940’s? Am I misinformed on the amount needed for a lethal dose? And if so, how would it get into the body? I’m no toxicologist, but I know alpha particles can’t penetrate human skin.
