Abstract:
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.
