Study Ties Higher Radiation-Linked Cancer Deaths To U.S. Aircrew Jobs

A study published Monday, August 17, 2026, in JAMA Internal Medicine found U.S. flight attendants and pilots had the highest rates of death from radiation-linked cancers among more than 500 occupations examined.[1]

Researchers analyzed more than 12 million U.S. death certificates that included occupational information.[1] Flight attendants had about 50% higher odds and pilots about 36% higher odds of dying from radiation-linked cancers compared with the general working population.[1] About 6.9% of flight attendant deaths and 6.7% of pilot deaths were from radiation-linked cancers, versus 5% among the general workforce.[1]

The study covered more than 500 occupations and ranked flight attendants first and pilots second for deaths tied to radiation.[1] The Federal Aviation Administration recognizes ionizing radiation exposure in aircrews but sets no federal dose limits and does not require routine radiation monitoring.[1]

The findings underscore a regulatory gap that some say could warrant routine monitoring or exposure limits for U.S. aircrews to better protect worker health.
