This document is intended to serve as a guide to Version 3 of Air Transport of Radiation ATR as it is different from Version 2. The ATR code contains a parameterization of a comprehensive transport data base for neutrons, secondary gamma rays, prompt gamma rays and x-rays and provides a detailed description of weapon radiation environments. Previous ATR reports dealt with the basic parameterization aspects. Specifically, Version 3 contains the parameterization of the new neutron and secondary gamma ray data base that was calculated using the latest DNA approved cross sections for air. Other improvements to the ATR code that are described in this report include parameterization and inclusion into ATR of new air-over-ground correction factors, low energy x-ray calculations, new fission source, and new convenience options.
