Description
Summary:This study discusses the optimization of CaS[O.sub.4]: Dy phosphor for its use in environmental monitoring program. In India environmental gamma radiation monitoring, using TLDs is being carried out since last four decades on regular basis. Investigations are made to determine optimum thickness of teflon disc and doping concentration. Teflon disc 0.8 mm thick was found optimum with the 0.2 mol% Dy concentration for highest sensitivity for environmental gamma radiation monitoring. Keywords Environmental TLD * Gamma radiation * Dosimetry * Teflon disc
