Flight crews face the highest occupational radiation exposure in the U.S. workforce, yet lack regulatory protections comparable to other radiation-exposed workers. Current FAA monitoring and communication approaches are inconsistent and insufficient, failing to address cumulative lifetime risks that vary by altitude, latitude, duration, and solar activity. The National Academies report, mandated by Congress under the FAA Reauthorization Act of 2024, urges the FAA to treat in-flight cosmic radiation as an occupational hazard and require airlines to implement comprehensive radiation safety programs. Tools for dose modeling and exposure tracking exist but are not uniformly deployed. Operators must now establish standardized dose-tracking systems and improve access to estimation tools to mitigate long-term cancer risks. The sector faces operational changes affecting scheduling, training, and occupational health compliance.
