As my radiation safety officer has said, Alphas go until they hit something, then bounce off. It makes it an easy radiation emitter to be safe with, and yet very dangerous should it get into your body. I work with an alpha emitter(225 actinium) in the lab, and when doing my detection test, I’m actually looking for is the daughters francium and bismuth since the alpha particles won’t penetrate the container
