The thing about things with longer half lives is that while they last a longer time they're also less radioactive. The same decay events that cause dangerous radiation are the same decay events that lead to the material's half life. I would guess that it's worse to breath in Plutonium-239 than to breath in asbestos but I'm not sure and the Wikipedia page is short on information that would convince me either way. https://en.wikipedia.org/wiki/Plutonium#Toxicity https://en.wikipedia.org/wiki/Plutonium#Toxicity
