摘要

Human exposure to radiation from the confines of aircraft can be estimated using models built in radiation transport codes to produce dose-lookup tables, and inputting the particle spectrum of interest. In this work, we report dose-lookup tables for energy depositions as a function of depth in water, a tissue surrogate, as a function of incoming particle species and energy as well as the aircraft altitude. These results are part of the Earth-Moon-Mars Radiation Exposure Module (EMMREM) project. The calculations of the energy depositions are carried out using the HETC-HEDS Monte Carlo radiation transport code developed at Oak Ridge National Laboratory and the University of Tennessee. The calculations transport the incident particles through various representative atmosphere densities, corresponding to balloon, private aircraft and commercial aircraft altitudes; then through an assumed aluminum fuselage of 1g/cm~2 thickness before entering the human tissue surrogate.
