An autoradiograph is an image on an X-ray film or nuclear emulsion produced by the pattern of decay emissions from a distribution of a radioactive substance. Alternatively, the autoradiograph is also
A radioactive surgeonfish makes its own X-ray. The bright area is a meal of fresh algae. The rest of the body has absorbed and distributed enough plutonium to make the scales radioactive. The fish was alive and apparently healthy when captured.
Beta particle

A beta particle, also called beta ray or beta radiation, is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus, known as beta decay. There are two for

Blue Cherenkov radiation light being emitted from a TRIGA reactor pool is due to high-speed beta particles traveling faster than the speed of light (phase velocity) in water (which is 75% of the speed of light in vacuum).
