Introduction: Flight crew are exposed to elevated levels of cosmic ionizing radiation of galactic and solar origin and are among the more highly exposed occupational groups to ionizing radiation in the U.S., with annual doses ranging from approximately 0.2-5 mSv. Cosmic radiation dose depends primarily on altitude and geomagnetic latitude and to a lesser degree on solar activity and phase of the solar cycle. NIOSH is conducting several epidemiologic studies examining the relationship between cosmic radiation exposure, among other factors, and reproductive health of female flight attendants. Estimation of historical cosmic radiation dose is an essential component of these studies. One aim of this study was to measure cosmic radiation doses on a series of flights as a function of altitude, distance flown, latitude and longitude, and to compare dose-equivalent data collected on specific flights with doses estimated using the CARI computer program developed by the Federal Aviation Administration. CARI estimates will be used for dose reconstruction for the epidemiologic studies.
