Energy and Angular Distribution of Neutrons and Gamma Rays - Operation BREN

Abstract

In order to understand better the transmission and scattering of radiation in air, a series of measurements were made to determine the energy and angular distributions at large distances from the Oak Ridge National Laboratory Health Physics Research Reactor and an 800-curie Co(60) source. Both sources were positioned at various elevations on a 1527-ft tower while data were acquired by detectors located in collimators at either 750 or 1000 yd from the base of the tower. Good measurements were obtained of neutron and gamma-ray doses from the HPRR and gamma doses from the Co(60) source as a function of angle of incidence. Scintillation spectra of the gamma rays from the Co(60) source were also obtained. No useful spectrum information was obtained from the HPRR.
