Gamma Rays

Gamma rays are electromagnetic waves or photons emitted from the nucleus of an atom, typically with wavelengths of less than 3 pm. A highly penetrating type of nuclear radiation. Gamma ray emission is a decay mode by which the excited state of a nucleus de-excite to lower (more stable) state in the same nucleus.

Wavelengths from about 10-14 10-10m.

Gamma rays are used to sterilize food.

High-Intensity Gamma

A level a gamma radiation flux on the order of 10E4 roentgens or higher.
