Alpha particles lack the energy to penetrate even the outer layer of skin, so exposure to the outside of the body is not a major concern. Inside the body, however, they can be very harmful. If alpha-emitters are inhaled, swallowed, or get into the body through a cut, the alpha particles can damage sensitive living tissue. The way these
WebHow far do beta particles travel in the air? about one metre Beta particles with an energy of 0.5 MeV have a range of about one metre in air; the distance is dependent on the particle energy.
