FACTORS AFFECTING THE USE OF CAF2:MN THERMOLUMINESCENT DOSIMETERS FOR LOW-LEVEL ENVIRONMENTAL RADIATION MONITORING
Gross, K., E. McNamara, AND W. Brinck. FACTORS AFFECTING THE USE OF CAF2:MN THERMOLUMINESCENT DOSIMETERS FOR LOW-LEVEL ENVIRONMENTAL RADIATION MONITORING. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/4-76/035 (NTIS PB258486), 1976.
An investigation was made of factors affecting the use of commercially-produced CaF2:Mn thermoluminescent dosimeters for low level environmental radiation monitoring. Calibration factors and self-dosing rates were quantified for 150 thermoluminescent dosimeters. Laboratory studies were made of precision, linear response to dose rate, effects of light, and time-dependent fading. A standard laboratory procedure was devised and a computer program was written to calculate, analyze, and store the large amounts of data that were accumulated. Extensive environmental measurements were subsequently carried out at the Vermont Yankee Nuclear Power Station. The results of this investigation indicate that selected dosimeters, when properly calibrated and corrected for self-irradiation, can be used for accurate and reliable monitoring of low-level environmental radiation.
