... Beta Decay: Medium-level radiation from the emission of beta particles (electrons). Positron Emission: Medium-level radiation from the emission of a positron, which is the same as an electron, only with a positive charge, converting a proton into a neutron. Electron Capture: When an atom takes in an ...

... Nuclear Fission • Reactions in which an atom's nucleus splits into smaller parts, releasing a large amount of energy in the process. Most commonly this is done by "firing" a neutron at the nucleus of an atom. The energy of the neutron "bullet" causes the target element to split into two (or more) e ...
