Gamma Radiation at the Air-Ground Interface

Abstract

Measurements were made at the Nevada Test Site of dose rates produced by two large gamma-ray sources positioned in a level, clear area. The distance between each source in turn and the detectors was varied from about 10 m to almost I km, and the height of the detectors was increased from 0 to 148 m, or roughly one mean free path. The data obtained with several ionization chambers are presented and discussed. These data are to be used in determining the effect of the air-ground interface on gamma-ray dose rates produced by point and distributed sources on the ground.
