摘要

As a result of the recent recommendations of the ICRP-60, and in anticipation of possible regulation on occupational exposure of Canadian-based aircrew, an extensive study was carried out by the Royal Military College of Canada over a one-year period to measure the cosmic radiation at commercial jet altitudes. A tissue equivalent proportional counter was used to measure the ambient total dose equivalent rate on 62 flight routes at various altitudes and geomagnetic latitudes. These data were successfully compared to other experimental work at the Physikalisch Technische Bundesanstalt and to predictions with the LUIN computer code. A model was derived from these data to allow for the interpolation of the dose rate for any global position, altitude and date. Through integration of the dose-rate function over a great circle flight path, a computer code was further developed to provide an estimate of the total dose equivalent on any route worldwide at any period in the solar cycle.
