Statement from the 1983 meeting of the International Commission on Radiological Protection.

Exposure to radioactive materials must be constrained by the relevant dose-equivalent limits recommended in ICRP Publication 26 (1977) to reduce stochastic effects to an acceptable level and to prevent non-stochastic effects from occurring in the organs and tissues of the body. An ALl of a radionuclide or a DAC for submersion in an atmosphere contaminated with a radioactive chemical ly inert gas is then determined by the dose equivalent to which the organs and tissues of the body are committed as the result of such exposures. The values of ALJ and DAC recommended in I C RP Publication 30 are for workers based on a Reference Man; the factors by which they would differ from those that would be appropriate for members of the public are many and various, as discussed below.
