Flight crews receive among the highest occupational doses of ionizing radiation in the U.S. While estimated annual doses generally remain below recommended limits, questions remain about what cumulative exposure over the course of a career may mean for long-term health.
Some studies have reported elevated rates of certain cancers among pilots and flight attendants, but the evidence is not conclusive enough to determine whether occupational radiation exposure is the cause. Other aspects of aviation work — including other types of exposures and circadian disruption — may also affect health outcomes.
Our new report examines radiation exposure among flight crewmembers and recommends more consistent radiation safety programs, education, and career-long exposure tracking.

A new congressionally mandated National Academies report is bringing renewed attention to those questions, recommending a more consistent approach to occupational radiation safety across the aviation industry.
