Air-kerma rate constant
Revision as of 14:15, 23 February 2019 by icrpaedia>Clement
A characteristic constant for a radionuclide, which is defined in terms of an ideal point source, as , where is the air-kerma rate due to photons (gamma and x rays) of energy greater than δ at a distance l in a vacuum from a point source of the radionuclide of activity A.
