Radiation Protection


Radiation Protection is a general term applied to the profession/science related to protecting man and the environment from Radiation hazards. Strictly speaking, it should represent all forms of radiation (e.g. Ionising and Non-Ionising) but is mostly applied to ionising radiations. See Health Physics for related definition.

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?
