Book Synopsis Energy and Angular Distribution of Neutrons and Gamma Rays by : J. H. Thorngate
Download or read book Energy and Angular Distribution of Neutrons and Gamma Rays written by J. H. Thorngate and published by . This book was released on 1969 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where possible, these data have been compared with data from previous field experiments. In every case, they were compared with calculations which approximated the experiment. Agreement in both cases is generally good, and this strengthens confidence in calculated results.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Energy and Angular Distribution of Neutrons and Gamma Rays - Operation HENRE. by :
Download or read book Energy and Angular Distribution of Neutrons and Gamma Rays - Operation HENRE. written by and published by . This book was released on 1969 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The HENRE experiment, conducted at the Nevada Test Site in the winter and summer of 1967, was an extension of the experimental programs related to the Ichiban program to determine the doses received by the survivors at Hiroshima and Nagasaki. This report presents the data obtained on the neutron and gamma-ray dose as a function of polar angle, the fast neutron spectrum as a function of distance, and the high energy gamma-ray spectrum as a function of polar angle. It was found that the neutron spectrum did not reach equilibrium within the distances at which measurements were made. This has an effect on the dose as a function of polar angle measured with different air densities. In addition, the measurements show the gamma-ray dose received from angles below the air-ground interface is affected by the diffuse source of gamma rays. Where possible, these data have been compared with data from previous field experiments. In every case, they were compared with calculations which approximated the experiment. Agreement in both cases is generally good, and this strengthens confidence in calculated results.

Book Synopsis General Correlative Studies, Operation Bren by : John A. Auxier
Download or read book General Correlative Studies, Operation Bren written by John A. Auxier and published by . This book was released on 1963 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A summary of the utilization of the Health Physics Research Reactor and a Co Co60 source during Operation BREN has been prepared, and the pertinent meteorological data have been tabulated. Normalization factors for air dose, as it depends on air density and reactor power level, are obtained as a function of source height; typical dose vs. distance curves are presented. For a source height of 1125 ft and with the detector at the surface of the ground, the relaxation length in air is 230 yards for neutrons from the reactor, 311 yards for gamma radiation from the reactor (including gamma rays from inelastic interactions by neutrons in air), and 256 yards for the gamma rays from Co60. These reduce to 181, 245, and 200 yards, respectively, at 760 mm Hg pressure and 0 deg. C. This is the third of a series of Operation BREN reports and the first concerning experimental results.

Overall agreement was found to be good.
