The Air Transport of Radiation (ATR) Code: Development and Testing of ATR5

Abstract

The Air Transport of Radiation (ATR) code is the standard model for initial radiation dose (kerma free-in-air) from nuclear weapons in uniform air and air-over ground geometries. ATR predicts free field dose from neutron, gamma rays, from a parameterized data base. This report describes modifications made to the code to provide for improved uniform air and air-over-ground dose distributions. Effects of atmospheric moisture are now accounted for. The fission product radiation model has been modified to include contributions from individual fissile isotopes and has been provided with empirical corrections to allow it to better replicate observed dose values. The resulting version of the code is ATR5. Keywords: Radiation transport; Nuclear weapons; Dose; Kerma; Neutrons; Gamma rays; Fission products.
