The use of thermoluminescence for radiation dosimetry is described and the limitations of previously employed thermoluminescent dosimeters are pointed out. It is shown that a special manganese-activated calcium fluoride phosphor permits detection of x-ray and gammaray doses in the milliroentgen range and offers promise as a replacement for the photographic film badge in health physics applications. The dosimeter consists of a coating of the phosphor bonded to a small metal supporting disk by conventional enameling techniques. It is read by inserting it into a small preheated oven, which causes the dosimeter to luminesce with an intensity proportional to the radiation dose. The thermoluminescence is measured by a phototube and recorded. (auth)
