Commercial pilots and flight attendants may face greater odds of dying from cancers linked to radiation exposure than many other professions, a new study suggests. Researchers say high-altitude cosmic rays could be the culprit behind the elevated risk seen in those who routinely fly long distances and spend substantial time above sea level.
The study points to radiation exposure encountered at cruising altitudes where the atmosphere provides less shielding from cosmic radiation. It highlights flight crews, including pilots and attendants, as having higher mortality from certain cancers compared to hundreds of other occupations examined.
Officials behind the research are advocating for increased awareness among airlines, health professionals, and workers who spend significant time flying. They also call for health screenings that consider this potential risk, to help detect cancers earlier in affected individuals.
Details on the study’s scope, methodology, and exact numerical risk estimates are not provided in the available summary. Researchers emphasize the need for further investigation to confirm findings and to determine practical steps for monitoring and prevention within the aviation industry.
As airlines continue to balance safety, efficiency, and worker wellness, the study underscores a possible dimension of occupational health that could influence future policies, training, and health services offered to flight crews.
