Preparation and investigation of thermoluminescence properties of CaSO4:Tm,Cu.
A new sort of thermoluminescent phosphor has been developed with the purpose of enlarging the range of linear dose-response. The thermoluminescence properties of CaSO(4):Tm,Cu, prepared according to our method, were studied in the dose range of 0.5 Gy-125.0 kGy. The results of the present work show that the CaSO(4):Tm,Cu is an excellent new dosimetric material due to its relatively simple glow curve, as a consequence of its simple trap system. Several applications are possible in dosimetry due to its wide range of linearity (2 x 10(-6) to 2 x 10(3) Gy), from environmental and space dosimetry to accidental and high-dose irradiation, e.g. gamma irradiation facilities, electron accelerators, nuclear power plants, radiotherapy, medical physics, and so on.
