Flight attendants and pilots face a higher risk of dying from radiation-related cancers, according to a new study. This risk is greater than that of people who work with radioactive materials. Cosmic radiation from space is the source, with exposure increasing at high altitudes.

The study provides new evidence on the link between frequent flying and higher cancer death rates among pilots and flight attendants. Further details on the study's findings are available.

The research was published by JAMA Internal Medicine, with accompanying commentary from Australian radiation experts who were not involved in the study.
