Summary of annual records of chemical quality of water of the Arkansas River in Oklahoma and Arkansas; 1945-52, a progress report

On the air-scattering of gamma rays from thick uranium sources
Arthur Y. Sakakura
1955, Trace Elements Investigations 595
Semiquantative interpretation of data from airborne radioactivity surveying requires detailed knowledge of air-scattered gamma-ray intensity at considerable air distances from natural, thick uranium sources. Based on the concept of an elementary source of infinite thickness rather than on the classical point source, semi-empirical expressions, are developed for measured gamma-radiation intensities from . the...
