| 中文摘要: |
| 初级宇宙射线是来自于太阳和太阳系外的高能粒子，其进入地球大气层后与大气中的原子或分子相互作用产生次级宇宙射线，次级宇宙射线是航空机组人员职业活动中受照剂量的主要辐射来源。航空机组人员是电离辐射暴露水平最高的职业人群之一，开展常规个人剂量监测或估算是非常必要的，但由于宇宙射线辐射场成分复杂，航空机组人员受照剂量监测并不简单。寻找合适的剂量监测方法和了解航空机组人员剂量水平对于保护其职业健康具有重要意义。本文就航空机组人员所接触的次级宇宙射线的监测方法、剂量计算方法和受照剂量水平作一综述，旨在为今后加强我国航空机组人员剂量监测和健康管理提供思路。 |
| 英文摘要: |
| The high-energy particles from the sun and from outside the solar system and then enter the Earth's atmosphere and interact with the nuclei of atmospheric constituents, leading to secondary cosmic rays, which are the main radiation source to aircrew. Routine individual monitoring or dose estimation for aircrew is necessary because of the high level exposure to radiation. However, dose monitoring for aircrew is not a simple task due to the complex components of cosmic ray radiation field. To protect occupational health of aircrew, it is important to seek appropriate dose monitoring method and to be aware of cosmic radiation level. This review gives an overview of dose monitoring method, dose calculation method, and dose levels of occupational exposure of aicrew from cosmic rays, in order to provide new input for strengthening dose monitoring and health management of aircrew in China. |
