Actually, no, but the stuff you want to watch out for is gamma radiation. Alpha won't penetrate you clothes, and beta will burn your skin, but doesn't really penetrate much past the surface. Gamma, though, goes right through you bouncing off cell nuclei and DNA along the way. The Victoreen 715 has a "beta shield" so it will ignore all but gamma radiation, which, when you're hunkered down in a shelter, is what you want to know about.
Thank you Brother. Hopefully we’ll never find out.
