Analysis of Scintillation Spectrometer Observations of the Penetration of Cs137 Gamma Radiation through Water

Abstract

Spectral modifications of Cs137gamma radiations produced by penetration and diffusion through water have been observed. A single crystal of NaI(Tl) was used to observe the pulse‐height distributions produced by radiation from both plane parallel and point isotropic sources. Inversion of the pulse‐height distribution was carried out by use of an analog computer to obtain the spectral distribution of radiation.
