View source for Air-kerma rate constant

A characteristic constant for a radionuclide, which is defined in terms of an ideal point source, as <math>   \Gamma _\delta =</math> <math>\frac{\iota^2\ \dot{K}_\delta}{A} </math> , where <math> \dot{K}_\delta</math>is the air-kerma rate due to photons (gamma and x rays) of energy greater than δ at a distance <math>\iota</math> in a vacuum from a point source of the radionuclide of activity A.
