Phototransferred TL studies in CaSO4:Dy

Abstract
Phototransferred thermoluminescence (PTTL) studies in CaSO4:Dy have relealed two high temperature peaks at 500 and 570 degrees C in gamma -exposed phosphor. Employing 365 nm for phototransfer at elevated temperature (95 degrees C), PTTL can serve a useful technique for re-estimation of the radiation exposure.
