Abstract

With the increase of the modern aircraft operating ceiling and autonomy, radioprotection and flight safety organizations began to show concern about the control of ionizing radiation dose level received by aircraft pilots, crew and electronic equipment. The study of the effects of atmospheric cosmic radiation on avionics, crews and in-flight detector systems requires a detailed description of the incident radiation field in the aircraft. In this context, the objective of this work is to develop a computational platform capable of performing calculations of the cosmic radiation transport through the atmosphere and of determining the radiation field from ground up to 100 km altitude at any geographical point in a more realistic way, with unprecedented detail of the angular and energy distribution of 15 different particles. Other differentials of the proposed platform are: the possibility of choosing physical models and inclusion of scattering effects in the soil. The radiation intensity will be modulated by neutron counting in a ground based monitoring station. An interface application will allow one to calculate the energy deposition by different particles at any geographical coordinate, altitude (from 0 to 100 km) and date, and aims to cater to both the general public and crews as well as researchers. The proposed platform presents a more advanced modelling of physical effects than those currently available in the world and is the first developed in South America, serving as a tool for studies involving atmospheric physics, space weather and cosmic radiation effects, and has already aroused the interest of companies of the Brazilian aeronautical sector.
