[en] Basic characteristics of phosphate radioluminescent dosimeters are described, which are used in personnel dosimetry in Czechoslovakia. The chemical composition (in wt.%) of glass is as follows: 82.9 P₂0₅ - 5.4 Al₂0₃ - 8.9 MgO - 2.65 SrO -0.15 MnO. The special apparatus designed for measuring parameters of the detectors and the mathematical technique developed for calculating gamma radiation doses allow to determine the doses ranging from 10^3- rad to 10³ rad with 20% accuracy. The data are presented on the dependences of the measured signals on time (up to 70 days), heating temperature (100-400 deg C) and gamma radiation (20-800 keV). The spent detectors restore their properties after special treatment. The possibility of repeated control measurements is stated as an important merit of the method developed
