Abstract

Empirical parameters for two differential gamma-ray albedo formulas, originally proposed by Chilton and Huddleston, are presented for water, concrete, iron and lead, for 12 photon energies ranging from 0.1 to 10 MeV, and for reflected doses based on the ambient dose equivalent, the effective dose equivalent, and the exposure. The parameters were obtained by fitting the albedo formulas to MCNP calculated albedo values over the complete ranges of incident and reflected directions.
