             graphic densitometric measurement

Describes determination of the dimensions of the greatest radiation field at specified distance from the focal spot symmetrical with respect to the specified reference axis, with its edges parallel to the major axes, in which the distribution of relative air kerma rate along the major axes does not fall by more than 70% of the air kerma rate on the reference axis.
