抄録
Self irradiation of the CaSO4: Tm-TLD (National UD-200S), a commercial thermoluminescense dosimeter (TLD) of high sensitivity, was measured by keeping 10 samples taken from each of 10 batches of the TLD in a lead brick enclosure located underground for 20 days.<BR>In one batch was observed a very high self-irradiation of 186±26 fA/kg (2.6±0.36μR/h), which was about 3 times as large as for the other 9 batches.<BR>The source of this high self irradiation was investigated by the analysis of variance and identified to be the cap of the holder of thermoluminescent detectors which incorporates the Sn-Pb alloy filter for the energy compensation.
