Description

The dosimetric properties of RTL materials made in Poland and the U.S.A. (Harshaw) used for natural background measurements were investigated. The method of measurement was developed which enables to trace the changes of fading and RTL sensitivity of dosimeters during their long-term exposures in field conditions. It was stated that for materials not sensitizing when heated (CaSO4:Dy, CaF2:Dy, CaF2:Mn) a simplification of standard annealing process can be applied. For that reason CaSO4:Cy as the best of investigated materials was chosen for natural background measurements in the form of tablets made of CaSO4:Dy powder in the mixture with teflon. (author)
