Research progress on occupational hazards of cosmic radiation for aircrew

Abstract

According to the data released by the Civil Aviation Administration of China in 2020, there are more than 60000 pilots and more than 100000 flight attendants in China working with certificates in various airlines. The health of these aircrew is the basis for maintaining and continuing the smooth development of civil aviation. Aircrew are exposed to cosmic radiation at high altitudes. However, because the types of cosmic radiation are complex, changeable, and difficult to measure accurately, there is no definite conclusion as to whether it has any effect on the health of aircrew. This paper introduced the impacts of cosmic radiation on aircrew, reviewed the estimation of cosmic radiation dose at home and abroad, and summarized the cosmic radiation dose measurement methods and their limitations. It also pointed out the shortcomings of existing occupational health management of aircrew and put forward new suggestions on strengthening the health management of radiation hazards for aircrew.
