| Abstract:: |
| High-energy particles from primary cosmic rays interact with the earth's atmosphere to form secondary cosmic rays, collectively composing cosmic radiation. Due to long-term working at high altitude, the aircrew have become one of the most highly exposed occupational groups, with in-negiliable health status. This study presents a narrative review of the research findings relevant to the genotoxicity and cellular damage induced by cosmic radiation exposure, the radiation doses received by aircrew, and the cancerous and non-cancerous health effects. The aim of the present study is to provide new inputs and scientific basis for health risk assessment and radiation protection strategies for aircrew as one of exposed occupational groups. Most studies available have shown that the risks of breast cancer and skin cancer to aircrew are significantly higher than in the general population, of which the research findings on other cancer effects are still inconformity each other. The discrepancies between different research result are mainly attributed to such factors as sample size, control of confounding factors, and impact on healthy workers. |
