Repeated evaluation of TL-dosimeter (CaF$sub 2$) values through uv- photostimulation

By means of uv-stimulated thermoluminescence in natural CaF/sub 2/, repeated readouts on TL-dosimeters are possible in the range of 50 to 3000 rad. The uv-sensitivity of luminophor appears as an unwanted signal, which is suitable for creation of an uv-dosimeter. (auth)
