Definition: | for a photon emitter, the product of the exposure rate $\dot{X}$, at a given distance l from a point radiation source of that emitter and the square of that distance divided by the activity A of the radiation source neglecting attenuation $\Gamma =\dot{X}\left({l}^{2}/A\right)$ Note 1 to entry: This entry was numbered 393-14-82 in IEC 60050-393:2003. | ||
