What is positron emission decay? Positron emission or beta plus decay (#beta#+ decay) is a particular type of radioactive decay and a subtype of beta decay, in which a proton inside a radionuclide nucleus is converted into a neutron while releasing a positron and an electron neutrino (Î½e). [1] Positron emission is mediated by the weak force. The positron is a type of beta particle (#beta#+), the other beta particle being the electron (#beta#-) emitted from the #beta#- decay of a nucleus. This is a very helpful video by Tyler DeWitt:
