Beta Plus Decay can produce positrons B+ decay occurs when energy is applied to a proton, and the resulting interaction causes the proton to convert into a neutron and a positron. The neutron remains captured in the nucleus, while the positron is ejected, sometimes at high speed. Note that B+ decay cannot occur spontaneously - it requires energy, usually in the form of a high speed collision with another particle
