| dc.description | Throughout their working life, pilots and their cabin crew are exposed to natural background radiation levels, mainly caused by solar and galactic cosmic radiation. For this reason, since 1990, the International Commission of Radiological Protection ICRP recommended that air crews follow certain radiation exposure limits. There is research on this issue, mainly in the polar areas, where there are greater health effects. However, due to the lack of analysis in the equatorial region, the objective of this study was to evaluate the natural ionizing radiation in the cockpit on national and international flights of short and medium duration in South America, and determine if it exceeds the annual limits established by the ICRP. The Geiger Müller detector was used to perform the measurements in situ in July 2019, during the solar minimum, on the flights of Baltra Quito national and Bogotá Quito international of medium duration 1.5-3h, and Quito Guayaquil national of duration short less than 1.5 h. Additionally, through the CARI-6 software, the annual effective dose was estimated using parameters of origin and destination of each flight, duration, altitudes reached, and date. The results in situ indicated that, in the medium duration routes, the radiation dose was similar and directly proportional to the altitude, reaching a maximum rate of 3.5 pSv/h at 11.27 km high. However, when comparing the dose rate between a measured route and a calculated one, under equal conditions 0 latitude and solar minimum, the measured dose rate was higher. Through the simulations carried out with the CARI-6 software, 1.4 mSv/year of effective dose received by the crew was estimated, exceeding the permissible limits for the general public, but not the ones determined for the occupational exposed workers. Consequently, the occupational risk is minimal. | en |
