Cosmic radiation from space poses a significant threat to certain individuals. People who work at high altitudes, such as pilots and flight attendants, are more exposed to this radiation. A recent study examined the impact of this exposure on cancer death rates.

Researchers analyzed national data from a large group of people, over 12 million. The study's findings are published in a medical journal. Further details about the study and its conclusions are available, including commentary from experts in the field of radiation.
