Cosmic radiation exposure calculation for domestic flights departs from Fez

Abstract

This study aims to estimate the risks associated with the cosmic radiation dose received by crews and passengers on internal flights departing from Fez. The methods used are SIEVERT and the mathematical model which provides an estimate of the effective doses based on flight parameters are the flight duration, the atitude, the laltitude. The total cancer risk and genetic effects were estimated according to the ICRP. The effective doses determined by the SIEVERT and the mathematical model for the departure airport of Fez to the different national destinations are as follows: The measured dose values ranged from 0.40 µSv to 0.90 µSv and the calculated effective dose values ranged from 1.44 µSv to 2.21 µSv. The risk of cancer with aircrew members and passengers computed ranged from 17×10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−5</sup> to 28×10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−5</sup> and 30×10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−6</sup> to 53×10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−6</sup>. And also, the risk of effects genetic with flight crews and travelers computed ranged from 3×10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−5</sup> to 5×10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−5</sup> and 7×10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−6</sup> to 12×10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−6</sup>. The results of the calculation differ with the measurements for internal flights from Fez. To mitigate the risk of potential health effects, safety measures must be taken to lower the dose.
