The assertion that radioactive elements having long half-lives makes them more dangerous always boils my piss.
Potassium-40 has a half-life of 1.5 billion years, yet a banana is a delicious and healthy snack.
Replying to @tryst@meow.social
@tryst the long half-life ones are kinda safer because they're not sitting there emitting vast amounts of radiation
short half-life ones bun out quickly, so avoid them for a few days/weeks. cobalt-60 was proposed for bombs because you could irradiate an area then invade it later.
it's the real mid-range ones that are nasty
