摘要
1991年,ICRP建议将空勤人员列入职业受照人群;2002年,我国颁布实施了《空勤人员宇宙辐射控制标准》。本文介绍航空飞行高度上的辐射环境及空勤人员辐射剂量的估算方法和常用的测量手段,并比较了不同方法的计算和测量结果。
In 1991, the International Commission on Radiological Protection, ICRP, enlisted air crew as a part of occupational exposure population. Chinese government, in 2002, promulgated and implemented the standards for controlling exposure to cosmic radiation of air crew GBZ 140-2002. This paper introduces the dose rate evaluation of cosmic radiation at the flight altitude and several common measurement methods and compares their calculations and results.
