Abstract

Photographic film was exposed to γ-rays from ²²⁶Ra and ⁶⁰Co to levels of 5 mR to 5, 000 R. Measurements of the Ag in the developed films by both (a) activation with neutrons from ²⁵²Cf and counting ¹¹⁰Ag (half life 24.4 sec) and (b) X-ray fluorescence correlated with the known exposures. In the lower ranges conventional optical density measure-ments were made, and the correlation with the activation and X-ray methods was good.
