RIngle-crystal lithium fluoride detectors

The use of lithium fluoride as detectors for thermoluminescence dosimetry is discussed. The principal characteristics of detectors of diameters 3, 8, and 10 mm are discussed, including: lower limit of detectable dose, repeated use of detectors, dependence of the thermally stimulated luminescence yield on the radiation dose, and loss of accumulated light sum during storage of the detectors. The detector preserves its characteristics to within + or - 15% after irradiation with a dose of 5 . 104 cGy
