The National Academies wants the FAA to move flight crew radiation exposure from advisory guidance into formal oversight. The report says current monitoring, tracking and risk communication are uneven, while cumulative cosmic radiation on long-haul and high-altitude flying can add material occupational risk over a career.
It also presses the agency to use its existing authority, expand access to the CARI dose model and require airline radiation safety programmes. For operators, that points toward tighter crew dose management and a more explicit compliance burden ahead.
