Abstract

Abstract Gamma-ray self-attenuation factors were calculated for sand samples collected in January 2011 at 11 selected locations covering the 6km extension of Camburi Beach, ES, Brazil. Samples apparent densities ranged from 1.36g/cm3 to 1.81g/cm3. The self-attenuation factors varied from 1.04 for the 152Eu 1408keV gamma transition of the lower density sample to 1.62 for the 152Eu 122keV gamma transition of the higher density sample.
