为提高RCA成员国的个人剂量监测水平,中国辐射防护研究院于1990～1992年参加了IAEA/RCA组织的三个阶段的个人剂量计的比对工作。从参加比对的个人剂量计看,它从简单型提高到多功能型,从只能测量照射量到可以测出不同能量下的射线剂量、剂量当量。比对结果表明,比对工作所采用的几种剂量计是可靠的。比对中,还校对了刻度剂量计用的校准辐射源。同时还指出了在剂量计结构、刻度系数和刻度方法等方面需加以改进的地方。 To improve the level of individual dose monitoring in RCA member countries, China Radiation Protection Institute participated in the three-phase personal dosimeter calibration of the IAEA / RCA organization from 1990 to 1992. From participating in the comparison of personal dosimeter, it increased from simple to multi-functional type, from only measuring the amount of radiation can be measured under different doses of radiation dose, dose equivalent. The comparison shows that several dosimeters used in comparison work are reliable. The alignment also calibrated the calibration radiation source for the scale dosimeter. It also points out the areas to be improved in terms of dosimeter structure, scale factor, and scale methods.
