WebIt was realized that one of the causes of the poor dose uniformity was that X-rays, unlike gamma radiation from a cobalt-60 source, contain a wide energy spread, from about 30 to 150 keV. In the case of an X-ray irradiator, the low-energy X-rays (photons) deliver a high dose at the surface near the entrance of the canister, resulting in a high DUR.
