Cosmic Radiation Exposure of Flight Attendants: A Comprehensive Analysis

Flight attendants and pilots are occupationally exposed to cosmic radiation at aircraft altitudes, with mean annual effective doses estimated at 2.5 ± 1.0 mSv. This places aircrew among the most highly exposed occupational groups, often exceeding doses received by nuclear industry workers. This comprehensive analysis examines the sources, dosimetry, and health implications of cosmic radiation exposure for flight attendants. It reviews the regulatory framework, including ICRP and NCRP limits for occupational exposure and fetal protection during pregnancy. The study highlights the importance of individual monitoring, route-specific dose variation (polar vs. non-polar routes), and the potential health risks, including cancer and heritable effects. A landmark 2023 ruling establishing liability for an airline due to cosmic radiation-related cancer underscores the growing legal and occupational significance of this issue. The analysis concludes with recommendations for airlines and crew members to minimize exposure and protect health.https://www.academia.edu/170492885/Cosmic_Radiation_Exposure_of_Flight_Attendants_A_Comprehensive_Analysis  https://medium.com/@jorbenadze65/cosmic-radiation-exposure-of-flight-attendants-a-comprehensive-analysis-cfc1af16b310
