Models of Photon Radiation in Air.
Abstract
A data base of photon transport in air for energies extending from 10 keV to 10 MeV was generated for parametric modeling for the ATR code. The data base was generated in two separate units; one for gamma-ray problems which has 18 energy groups from .02 MeV to 10 MeV, and the other, for x-ray problems which has 18 energy groups from 10 keV to 300 keV. The gamma-ray energy group structure is identical to the group structure for the secondary photons of the neutron ATR data base; thus allowing one to use ATR to obtain results for a complete neutron and gamma-ray radiation source problem. The x-ray data base was geared toward the special problems of obtaining accurate transport calculations for sources in the x-ray energy region.
