A large-scale study published in JAMA Internal Medicine, led by researchers from Harvard Medical School, School and Brigham and Women’s Hospital, has linked flight crews to an increased risk of death from radiation-related cancers. By analyzing approximately 12.7 13 million US U.S. death certificates records between 2020 and 2024 across 503 different occupations, researchers found that radiation-related cancers accounted for roughly 6.9% of deaths among flight attendants face nearly 50 percent higher odds of dying from these cancers, while pilots face roughly 36 percent higher odds and 6.7% among pilots, compared to approximately 5% in the general working population. The elevated risks specifically involve cancers associated with radiation exposure, such as leukemia, lymphoma, and various skin, breast, and thyroid cancers. The study notes that rates for cancers unrelated to radiation remained similar to other occupations, suggesting suggests that occupational exposure to cosmic radiation at high altitudes is a likely cause rather than lifestyle factors. While researchers acknowledge potential confounding factors like irregular working hours aircrew members may absorb between 3 and jet lag, the findings highlight a significant occupational health concern. Further data indicates that long-haul commercial pilots accumulate significantly higher levels 6 millisieverts of ionizing radiation annually annually, significantly more than nuclear power plant technicians. While nuclear operators typically receive between 0.2 and 0.8 mSv per year due to heavy shielding, pilots on long-distance routes accumulate between 1.5 and 3.5 mSv, with exposure reaching 4 or 5 mSv on polar routes. the average passenger. This disparity exposure is attributed to the lack of heavy shielding in aircraft and the reduced atmospheric protection cosmic radiation at high altitudes. altitudes, where the thinner atmosphere provides less protection. While the US Federal Aviation Administration recognizes ionizing radiation exposure, the research highlights that the agency does not currently establish federal dose limits or require mandatory monitoring. In response, labor Labor representatives have called noted that while these risks are known, crews often lack sufficient training or information regarding radiation exposure, leading to calls for increased accountability and better education regarding these occupational health risks.
