本文介绍了第二机械工业部所属的12个单位首次个人剂量计照射量比对情况。参加这次比对的个人剂量计种类有:热释光剂量计(TLD)、辐射光致荧光玻璃剂量计(RPL-D)和胶片剂量计(Film-D),共计26组,731个。这次比对所选取的辐射能量为52keV、216keV 和~(226)Raγ谱,并且选取了9个参考照射量。比对结果表明,TLD、RPL-D 和 Film-D 所测得的值与参考照射量之比值落在0.70—1.30范围内的百分数分别为93.7%、75.9%和71.4%。此外,还分析了产生误差的原因,提出了外照射个人剂量监测中值得注意的一些问题。
This article describes the first personal dose of 12 units belonging to the Ministry of Machinery Industry to compare the amount of exposure. The personal dosimeters included in the comparison were TLD, RPL-D and Film-D, a total of 26 groups and 731. The selected radiation energies for this comparison were 52 keV, 216 keV and 226 Raγ spectra, and 9 reference irradiances were selected. The results of comparison showed that the percentages of TLD, RPL-D and Film-D measured values to the reference exposure fall within the range of 0.70-1.30, respectively, to 93.7%, 75.9% and 71.4%. In addition, the reasons for the errors were also analyzed, and some notable problems in the monitoring of personal exposure to external radiation were put forward.
