How far does beta radiation travel in air
Web20 mrt. 2024 · Such beta emitters are used in medical applications, such as treating eye disease. In general, beta particles are lighter than alpha particles, and they generally … WebA beta particle is emitted from the nucleus of an atom during radioactive decay. The electron, however, occupies regions outside the nucleus of an atom. The beta particle, like the electron, has a very small mass compared to the proton or neutron. Its mass is 1/1836 that of the proton mass or 1/1838 that of the neutron mass.

WebBeta radiation takes the form of either an electron or a positron (a particle with the size and mass of an electron, but with a positive charge) being emitted from an atom. Due to the smaller mass, it is able to travel further in air, up to a few meters, and can be stopped by a thick piece of plastic, or even a stack of paper.
