Yeah, a natural source of uranium ore wouldn’t be a great place to be around, if you don’t have the right protective equipment. Lots of potential for dust in the air, or on surfaces that you touch. The danger becomes inhalation or ingestion, bringing the radioactive material into your body.

I mean, as an alpha emitter the radiation can’t penetrate your skin. As long as you wash your hands afterwards it’s probably fine. You wouldn’t see me trying it though
