A brand new research has discovered that flight attendants and pilots face the best threat of dying from radiation-related cancers amongst greater than 500 occupations studied in the USA, surpassing even staff who deal with radioactive supplies instantly.
The findings had been revealed August 17, 2026, in JAMA Inside Drugs.
The analysis, led by Dr. Vishal Patel of Harvard Medical Faculty, analyzed greater than 12 million US demise certificates from 2020 to 2024 utilizing the Nationwide Very important Statistics System, drawing on information from almost 13 million decedents throughout 503 occupations, together with roughly 14,000 pilots and seven,000 flight attendants.
Researchers examined deaths from cancers linked to radiation publicity, together with leukemia, lymphoma, a number of myeloma, and cancers of the pores and skin, breast, thyroid, prostate, and central nervous system, whereas excluding lung most cancers to keep away from confounding the outcomes with smoking-related threat.

Odds of dying from radiation-linked most cancers far larger for crew
The research discovered that flight attendants had about 50% larger odds of dying from a radiation-related most cancers than the final working inhabitants, whereas pilots confronted roughly 36% larger odds.
In absolute phrases, radiation-related cancers accounted for about 6.9% of flight attendant deaths and 6.7% of pilot deaths, in contrast with 5% among the many normal working inhabitants, roughly one in 14 flight attendant deaths tied to those cancers.
Neither group confirmed elevated demise charges from cancers unrelated to radiation, a sample researchers say factors to office publicity, somewhat than life-style or socioeconomic elements, because the extra doubtless clarification.
Aircrew are estimated to accrue between three and 6 millisieverts of cosmic radiation per yr relying on flight paths, an order of magnitude larger than the roughly 0.4 millisieverts a median air traveler receives yearly from about 10 cross-country round-trip flights, in line with the Facilities for Illness Management and Prevention (CDC).
Whereas the FAA formally acknowledges pilots and flight attendants as occupationally uncovered to ionizing radiation, US aircrew, in contrast to radiation-exposed staff in different industries or aircrew in another international locations, are usually not topic to federal dose limits or monitoring necessities.
In a commentary accompanying the research, Australian radiation well being researchers Catherine Olsen and Ken Karipidis famous that fashionable scheduling has largely eradicated the lengthy, sun-drenched layovers as soon as thought to elucidate elevated pores and skin most cancers charges amongst aircrew, pointing as an alternative to cockpit and cabin radiation publicity because the extra doubtless driver.
The researchers really helpful annual pores and skin exams for aircrew on high-altitude routes, together with earlier or extra frequent mammograms for girls in these roles.
Union response
Following the research’s launch, Sara Nelson, President of the Affiliation of Flight Attendants-CWA (AFA-CWA), which represents 55,000 flight attendants at 20 airways, issued a press release calling for radiation-related most cancers deaths to be formally acknowledged as occupational deaths.
“The danger is thought, however crew are usually not knowledgeable or skilled. And, nobody is taking duty. Not like requirements in Europe, the FAA nonetheless doesn’t require airways to watch crew publicity to radiation,” Nelson stated.
She added that the findings reinforce what the union has argued for years, and known as on the business and regulators to take steps to mitigate the chance and supply care and advantages related to occupational mortality.
Radiation threat amongst aircrew has drawn scrutiny for years
This isn’t the primary time regulators and researchers have flagged aircrew radiation publicity as an space needing stronger oversight.
In June 2026, a Nationwide Academies report, requested by Congress below the FAA Reauthorization Act of 2024 and sponsored by the FAA, concluded that the company’s present strategy to monitoring and speaking cosmic radiation threat was “inconsistent and inadequate.”
That report really helpful treating in-flight cosmic radiation as an occupational hazard, with improved publicity monitoring, clearer crew training, and sensible methods to handle cumulative radiation dose over a profession, significantly for pregnant crew members.
The difficulty has additionally surfaced in particular person instances. In November 2023, South Korea’s Korea Employees’ Compensation and Welfare Service dominated that the most cancers demise of a 53-year-old Korean Air flight attendant was instantly linked to cosmic radiation publicity sustained over his 25-year profession, a lot of it on long-haul routes to North America and Europe that handed by the Arctic, a area with comparatively larger cosmic radiation ranges.
Knowledge cited from South Korea’s Nuclear Security and Safety Fee discovered that flight attendants there have been uncovered to common most radiation ranges of 5.42 millisieverts per yr between 2017 and 2021, greater than 5 instances the usual permissible restrict of 1 millisievert for most people.
Korean Air stated on the time that it strictly manages particular person radiation publicity information and permits crew members to examine their collected publicity on a month-to-month foundation.
