Abstract : This report describes the results of infinite homogeneous air-transport calculations of neutrons, and prompt and secondary gammas. The results are presented in tabular form. The one-dimensional discrete-ordinates computer code, ANISN, was used to calculate neutron, neutron-induced gamma (secondary gamma) and prompt-gamma scalar fluences. Detailed group-scalar fluences are presented for 58 energy bands at 18 range points from 50 to 7200 meters for neutrons and secondary gammas, and at 17 range points from 50 to 6000 meters for prompt gammas. Angular fluences are not included as part of the output, due to the amount of data that would be involved. An assessment of the accuracy of the calculations is also included in the report. The report consists of two volumes. Volume 1 describes the calculations and discusses the results.
