Beta and low-energy photon irradiation of several commercial phosphors

Several commercially available thermoluminescent phosphors were evaluated with respect to their observed response to selected beta sources and K-fluorescent x rays. Phosphor responses were determined for in-air and on-phantom irradiations. Similar irradiations were done using a /sup 137/Cs source. Phosphor glow curves were recorded using a Harshaw Model 2080 TL Picoprocessor.
