During beta plus decay, a proton in an unstable nucleus transforms into a neutron, releasing a high energy positron and neutrino in the process. Beta particles carry away energy lost by the nucleus and are ionizing radiation. 00:00 - Intro 00:12 - Alpha and beta decay 01:12 - Beta minus decay of carbon-14 04:44 - Beta plus decay of nitrogen-13 07:47 - Neutrinos and antineutrinos 09:09 - Charge conservation 10:14 - Beta decay penetrating power and application ------------------ Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
