FIELD: physics; measurement.
SUBSTANCE: invention relates to method of measurement of cumulative dose or dose rate by means of solid-state detectors exposed to ionising radiation at high ambient temperatures. Method for measuring ionising radiation doze at high ambient temperature, including detector heat treatment at 900-950°C for 10-15 minutes and measurement of signal of optically stimulated luminescence excited at room temperature, implies additional exposure of heat-treated detector to 5-10 mGy fixed dose radiation at room temperature. Then optically stimulated luminescence signal is measured and its value is used to estimate high-temperature cumulative dose.
EFFECT: improved reliability, accuracy and validity of measurements, longer service-life of detectors.
