本文给出核工业部组织的、有厂、矿、院、所和高等院校等19个单位参加的第二次个人剂量计照射量比对结果。参加本次比对的有热释光剂量计(TLD)、辐射光致荧光玻璃剂量计(RPL-D)和胶片剂量计(Film-D)三种类型,共72组、222个剂量计。比对所选取的辐射是有效能量为47keV 的重过滤 X 射线和~(226)Ra 的γ射线。选取的参考照射量值,对于 TLD 是62—66mR;对于 RPL-D 和 Film-D 是110—160mR。由三种剂量计测得的306个数据表明,实测值(X_1)与参考照射量(X)比值的平均值为1.06±0.23,中位值为1.03,落在0.74—1.38范围内的约占总数的85%。
This article gives the results of the comparison of the exposure dose of the second personal dosimeter with 19 units organized by the Ministry of Nuclear Industry, including factories, mines, institutes, institutes and institutions of higher learning. A total of 72 groups and 222 dosimeters were included in this comparison. There were three types of TLD, RPL-D and Film-D. The filtered X-ray and the (226) Ra gamma-ray with an effective energy of 47 keV were selected for the selected radiation. The selected reference exposure was 62-66 mR for the TLD and 110-160 mR for the RPL-D and Film-D. The 306 data measured by the three dosimeters showed that the average of the ratio of the measured value (X_1) to the reference dose (X) was 1.06 ± 0.23 and the median was 1.03, accounting for about 0.74-1.38 85% of the total.
