The results of calibration of the dose rate from the beta source, incorporated in the RISO TL/OSL SYSTEM TL-DA-12, are presented. The quartz grains, separated from sediments by a typical procedure applied for thermoluminescence (TL) dating were used as a dosymetric material. The stability of thermoluminescence sensitivity of the material was achieved by the sequence of irradiating and the subsequent annealing of the grains. The calibrated 60Co and 137Cs sources were applied for irradiation with reference gamma doses. The calibration performed in January 1998 confirms the result obtained in 1996 with respect to the decay of activity of the beta source in the meantime.
