Radiation-induced biological effects on crew members: a combined analysis on atmospheric flight personnel

Human data on low dose rate radiation exposure and its effects are not readily available. A huge amount of such data may be obtained through flight personnel cohorts, in the form of epidemiological studies on delayed health effects induced by the cosmic-ray generated atmospheric ionizing radiation, to which flight personnel are exposed all throughout their work activity. All the available results from different studies on flight personnel exposure have been combined in various ways to evaluate the association between atmospheric ionizing radiation environment and health risks and to assess directions for future investigations.
