A recent study has revealed that flight attendants and pilots face a higher risk of radiation-related cancers compared to individuals working with radioactive materials. The study, published in JAMA Internal Medicine, examined more than 12 million death certificates and found that flight crews had the highest percentage of deaths from radiation-related cancers among over 500 different occupations.
Cosmic radiation, originating from space, poses a risk to individuals at high altitudes, such as those working in aviation. The study focused on cancers associated with radiation exposure, including leukemia, lymphoma, multiple myeloma, and various other types. Flight attendants were found to have the highest odds of dying from radiation-related cancers, followed by pilots.
The research challenges the belief that flight crews’ increased risk of skin cancer is solely due to sun exposure during layovers. Instead, the study suggests that the cockpit environment itself may be a significant contributing factor. The study also highlighted the potential impact of disrupted circadian rhythms on cancer risk, stemming from factors like jet lag and irregular work schedules.
Despite certain limitations in the study, such as the inability to quantify individual exposure levels, the findings underscore the need for increased awareness and monitoring of radiation exposure among flight crews. The Federal Aviation Administration’s acknowledgment of ionizing radiation exposure to aircrews raises concerns about the lack of federal dose limits or monitoring requirements.
The report emphasizes the importance of educating and informing aircrews about the risks associated with radiation exposure. Recommendations include considering annual skin examinations for individuals working on high-altitude flights, as well as earlier or more frequent mammograms for female crew members. Healthcare providers caring for pilots and flight attendants are advised to maintain a heightened awareness for cancer when evaluating these individuals.
