Irradiation

The process by which an article or body is exposed to a source of Ionising Radiation (either deliberate or by accident). A deliberate type of irradiation uses Gamma Rays or Electron beams to sterilize medical or food products. This type of irradiation is very different to the x-raying of items for security control where the exposures are much lower.

Radiation is one of the important factors in evolution. It causes mutation, and some level of mutation is actually good for evolution
