Characteristics of CaSO4(Mn) Film Phosphors for Use as Thermoluminescent Dosimeter

摘要

A thermoluminescent dosimeter of the thin film of CaSO4(Mn) was prepared and its optical and dosimetric properties were investigated.Glow curve, transmission and thermoluminescent spectra as optical properties of the film phos-phors were measured, and these properties were suitable for the dosimetry.Energy dependence, linearity of the dose and the fading as the dosimetric properties were meas-ured. Measurable minimum dose of the film phosphors was about 10-3R and their energy depend-ence on the low or high energy electrons was found.
