Studies of UV induced phototransferred thermoluminescence in CaSO4:Dy pellets.
The ultraviolet (UV) radiation response of the CaSO4:Dy pellets produced at IPEN/SP was studied using phototransferred thermoluminescence (PTTL). The PTTL characteristics of three different types of CaSO4:Dy pellets were investigated. The main parameters studied were: thermal treatments, post UV exposure storage time, PTTL response as a function of gamma dose, exposure time, radiant energy response and lower detection limits.
