This book was released on 1964 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The angular distribution of dose albedo was measured for "semi-infinite" concrete, aluminum and steel slabs irradiated by plane-parallel beams of Co-60 and Cs-137 gamma photons. The photons were incident on the slabs at angles, measured from a normal to the slab, of arccos 1.00, 0.75 and 0.50. For the necessary sensitivity, the reflected dose rate was measured by a digital dosimetry system using a plastic scintillator as the detector. An empirical formula for angular dose albedo was derived from the experimental data. Comparisons are made with the Monte Carlo calculations of D. J. Raso and the experimental results of C. E. Clifford (DRCL).

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Nuclear Science and Technology, Volume 5 presents the underlying principles and theory, as well as the practical applications of the advances in the nuclear field. This book reviews the specialized applications to such fields as space propulsion. Organized into six chapters, this volume begins with an overview of the design and objective of the Fast Flux Test Facility to provide fast flux irradiation testing facilities. This text then examines the problem in the design of nuclear reactors, which is the analysis of the spatial and temporal behavior of the neutron and temperature distributions within the system. Other chapters consider the three major ways of estimating shield effectiveness. This book discusses as well the purpose of variational principle, which is a characterization of a function as the stationary point of an appropriate functional. The final chapter deals with the solution of the Boltzmann transport equation. This book is a valuable resource for engineers.

This book was released on 1962 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The angular distribution of dose rate resulting from gamma rays of Co-60 and Cs-137 transmitted through various thicknesses of iron (0.737 in. and 1.6 in.) and aluminum (2 in., 4 in., and 9 in.) was measured. These experimental results are compared with Monte Carlo calculations. Comparisons over a limited range of these angular variables are also made with dose-rate distributions calculated from gamma-ray spectrometric data.

Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.

Download or read book A Mathematical Approach to Economy of Experiment in Determinations of the Differential Dose Albedo of Gamma Rays written by C. M. Huddleston and published by . This book was released on 1962 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treatments of the differential dose albedo of gamma rays on concrete have supposed that the albedo value is a function of: the energy of the incident gamma radiation, the polar angle of incidence, the polar angle of reflection (or scatter), and the azimuthal angle of reflection. It is demonstrated here that, if certain reasonable assumptions are made regarding the mechanism of reflection, it is not necessary to investigate variations in albedo with azimuthal angle or reflection. Once differential dose albedo has been determined for a complete set of incident and reflected polar angles with zero azimuth, albedo at any azimuth can be derived by a suitable transformation.

Download or read book Differential Dose Albedos for Calculation of Gamma ray Reflection from Concrete written by M. B. Wells and published by . This book was released on 1964 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differential dose albedos for gamma ray reflection from concrete were derived from Monte Carlo calculations of gamma ray scattering in air and concrete for source energies of 0.6, 1, 2, 4, and 7 Mev. Curves showing the albedo for reflection in the plane of incidence are presented for angles of incidence of *c = 0DG, 30DG, 45DG, 60DG, and 75DG. At incident energies greater than 2 Mev the computed dose albedos are smaller than those reported by Raso (also based on Monte Carlo) and those given by the Chilton-Huddleston formula. However, comparisons with experimental data for Cs-137 and Co-60 gamma rays reported by Jones, Schofield, Haggmark, and Gurney of USNRDL, C. E. Clifford of DRCL, and Barrett and Waldman of Technical Operations, Inc., indicate that the calculated albedos for these sources agree as well with the experimental data as do calculations based either on the Chilton-Huddleston formula or Raso's Monte Carlo calculations.
