Monitoring of exposures of aircrew members of airline operators registered in the Czech Republic has been performed since 1998. The individual effective doses are calculated using the computer code CARI annually. The calculations are based on information about participation of aircrew members on the specific flights and on the parameters describing the typical flight profiles of the flights; the latter is regularly verified with control measurements performed onboard aircraft. The results show that (1) the average annual effective doses in the period from 1998 to 2017 range from 1.3 to 2.1 mSv, (2) the maximum effective dose of a crew member is 5.7 mSv and (3) the annual collective effective doses range from 1.3 to 4.1 manSv. Combined relative uncertainty of the results is ~25%.
自1998年以来，一直在对捷克共和国注册的航空公司机组人员的辐射暴露情况进行监测。每年使用计算机代码CARI计算个人有效剂量。计算基于机组人员参与特定航班的信息以及描述航班典型飞行剖面的参数；后者通过在飞机上进行的对照测量定期进行验证。结果表明：（1）1998年至2017年期间的年平均有效剂量在1.3至2.1毫希沃特之间；（2）一名机组人员的最大有效剂量为5.7毫希沃特；（3）年集体有效剂量在1.3至4.1人·希沃特之间。结果的综合相对不确定度约为25%。
