Flight Attendants Cosmic Ionizing Radiation Exposure

Advertisement Cosmic Radiation Is a Significant Health Hazard in Large Doses According to the authors, the results suggest several environmental exposures — including ionizing radiation, circadian rhythm disruption, past exposure to secondhand smoke during flights (for those who worked during years prior to the in-flight smoking ban) and a variety of chemical agents with known carcinogenic potential — contribute to flight crews' elevated cancer risk, although ionizing radiation may be one of the most significant factors.
