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.

The definition of 'safe' is not strictly an engineering term; it's a societal term. Does it mean absolutely no loss of life? Does it mean absolutely no contamination with radiation? What exactly does 'safe' mean?
