Thee Physics of Beta Decay: A Primer for Security Applications

Beta decay is a slek interactive oy process that transformas a nukleyn with a nexyn an unstable nucles. In beta- minus (β β β) decay, a neutron is converted into a proton, an electron (then beta particlie), and an electron antineutrino. The atomic number progles by one, but the mass number dev unchanged. Conversely, in beta- plus (β mexide) decapture (EC) an extratives process, a proton is converted into a neutron, a positron, and elecino.
