前言 用飞行剖面图和前人测定的不同海拔高度的宇宙辐射的强度,为航线机组全勤成员计算了连续12个月所受宇宙射线的年剂量。方法 就用一次飞行总时间和飞机飞行剖面图分析了每一机组成员每一次飞行。首先计算在不同高度上的飞行时间,然后计算每一飞行阶段和高度全身所受累计辐射剂量。结果 机舱机组人员平均年飞行总时间为673h(从906h
INTRODUCTION Annual doses of cosmic rays sustained by 12 consecutive months have been calculated for all members of the flight crew by using flight profiles and the intensity of cosmic radiation of different altitudes measured by predecessors. The method analyzes each flight crew member flight with a total flight time and aircraft flight profile. First calculate the flight time at different altitudes and then calculate the accumulated radiation dose to the whole body for each flight phase and altitude. Results The average annual total flight time for cabin crew was 673h (from 906h
