A method for estimating the gamma-ray exposure received by non-occupational persons was devised. The method is based on the idea of using bearing quartz oscillator from the wrist watch, as monitor sample for tests on their thermoluminescence (TL). An average coefficient of variation in 15 samples was about 13% of the mean yield. The TL intensity from the quartz oscillator per 100R was from about 0.05 to 3 times of the background noise from the TLD reader.
