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.

This constant, a characteristic of a radionuclide, 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 l in a vacuum from a point source of the radionuclide of activity A.
