Earlier quoted context omitted.
> so that the toxicity of plutonium is roughly equivalent with that of nerve gas Is not exactly saying that it is not toxic. I tried looking for actually credible sources for toxicity, one Los Alamos publication claims: > For example, the LD50(30) for dogs after intravenous injection of plutonium is about 0.32 milligram per kilogram of tissue. Less than nerve gases, but still I'd classify as "quite toxic"
> ...after intravenous injection... Nerve agents are very readily absorbed through the skin. Metallic plutonium is not . The context here is (at worst) people poking around the outside of slightly-damaged nuclear warhead. Back in the day, I directly (metal-on-skin) handled lead totalling >1000X the human lethal dose... if administered via intravenous injection. No lethal effects were observed to occur.
(Also, don't let it hang out with its friends.)
