damage is related to the degree of tissue ionization produced by
radiation. Thus, a physical dose of alpha particles does not
produce the same amount of damage as that produced by the same
dose of beta particles, gamma rays, or X rays. ...the amount of
radiation that is required to produce 1 electrostatic unit of
charge in 1 cubic centimetre of air under standard conditions of
pressure, temperature, and humidity. For expressing the dose of
radiation absorbed in living tissue, the principal units are the
gray (Gy; 1 Gy = 1 joule of radiation energy absorbed per
kilogram of tissue) and the rad (1 rad = 100 ergs per gram of
tissue... ...of photographic emulsions are routinely used by
workers to monitor radiation exposure. The density of the
developed film can be compared with that of an identical film
exposed to a known radiation
