B. Wells and published by . This book was released on 1979 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents calculated time dependent energy deposition data for point isotropic gamma-ray sources emitting radiation in the source energy intervals. The radial intervals used in storing the energy deposition data are given. The delay time intervals used to store the energy deposition data are also given. The delay time is the time of energy deposition minus the time of arrival of the uncollided radiation. All source photons were emitted instantaneously by the source. The calculational methods used to compute the energy deposition data are described in Vol. I of this report.

Book excerpt: This report describes the RENDER calculational procedure that was developed for use in evaluating the spatial- and time-dependent energy deposition in air produced by anisotropic nuclear sources. The RENDER procedure utilizes nuclear energy deposition data generated for conical sources that were originally computed for line-beam sources through use of the ZAP, ZAPN, ZAPGAM and DEPO codes. The energy deposition data for air that are input to RENDER were generated for neutron and gamma-ray sources and for secondary gamma rays resulting from neutron capture and inelastic scattering in air. The energy deposition data for line-beam sources and for point isotropic sources were found to compare favorably with similar data reported in the literature. The RENDER procedure was run utilizing energy deposition data from the conical source-data base for a 9-to-10-MeV gamma-ray source and the results of the convolution over source emission direction and time were found to be in good agreement with the input data, indicating that the RENDER procedure performs the time-and-angle convolution correctly.

Wells and published by . This book was released on 1979 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents calculated time integrated energy deposition data for line beam gamma-ray and neutron sources emitting radiation in the source energy intervals The radial and polar angle intervals used in storing the energy deposition data are given. The geometry used in the energy deposition calculation is shown. The source radiation (neutron or gamma ray) is emitted from the source point in the direction Theta = 0 deg. The energy deposition was determined for regions formed by the intersection of the conical surfaces generated by the revolution of the radii R sub (i-1) and R sub i inclined at polar angles Theta sub (j-1) and Theta sub j, respectively about the source axis and the spherical surfaces formed by the revolution of the radii R sub (i-1) and R sub i about the source point. The calculational methods used to compute energy deposition data in air for line beam nuclear sources are described in Vol. I of this report.

This book was released on 1961 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: A program is considered which computes, as functions of time, altitude, and range, the electron concentration and resulting electromagnetic absorption for specified detonation and debris histories. The computation includes initial ionization due to x rays, gamma rays, neutrons, and debris, as well as delayed ionization due to the continuing beta and gamma radiation from the debris. It computes the transient recombination and quasi-equilibrium solutions for electron concentrations and the incremental electromagnetic wave absorption (decibels/kilometer) at the required altitudes for up to three specified frequencies. From these, the altitudes of specific electron concentration contours are interpolated and the one-way vertical absorption is obtained by trapezoidal integration. The computation is carried out for an atmosphere which approximates the 1959 ARDC atmosphere and includes the curvature of the earth. Atmospheric reaction rates are assumed to be those of the ambient air, except in the close-in, very disturbed regions, where approximate corrections appropriate to early times have been included.

Available in PDF, EPUB and Kindle. Book excerpt: This newly published book is intended for dual use as a textbook for students in radiation shielding courses and a reference work for shielding practitioners. It emphasizes the principles behind techniques used in various aspects of shield analysis and presents these principles in many different contexts. This approach is intended to provide a strong base of understanding in order to facilitate use of the large shielding codes that have come to dominate shielding design and analysis. An assumption is made that the reader has an understanding of mathematics through basic calculus and vector analysis as well as a knowledge of the nuclear physics of radioactive decay. For most chapters, problem sets are provided.
