The possibility of using TLD in the same procedures for checking the quality of equipment for radiation therapy using ion beams, which are widely used for photon and electron beams, is considered. The method of the high-temperature ratio HTR is considered to obtain a correction for a decrease in the sensitivity of TLD when they are irradiated with radiation with large LET. The empirical dependence of the correction value for measuring the absorbed dose using TLD on the HTR parameter was obtained. A number of points in the technique of measuring the absorbed dose using TLD in ion beams are discussed, which allow reducing the value the magnitude of the uncertainty in measurements.
