Cancer Incidence Associated with Cosmic Radiation Exposure in Aircraft Crew: Systematic Review and Meta-analysis

This systematic review aims to assess the incidence of cancer among aircraft crew members, including both pilots and cabin crew, as a result of occupational exposure to cosmic radiation. Due to the altitude and frequency of flights, aircrews are exposed to elevated levels of ionizing radiation, which includes both galactic cosmic radiation and solar particle events. These types of radiation may increase the risk of developing specific types of cancer. This review will synthesize data from observational and epidemiological studies to evaluate the strength of the association between ionizing radiation exposure and cancer incidence in this occupational group. The expected outcome is to generate evidence-based insights that contribute to the scientific understanding of aviation occupational risks and support the development of preventive strategies, health surveillance, and regulatory policies to protect flight personnel.
