The Effect of Radionuclide Fractionation on the Normalization Factor for Fallout Fields
Author: G. R. CrockerPublisher:
ISBN:
Category : Radioactive fallout
Languages : en
Pages : 52
Book Description
This report compares the normalization factor, r/hr per kt/mi]2, calculated for unfractionated fission products with the normalization factors calculated from field data for a near-surface silicate soil burst and a silicate soil cratering burst. The large discrepancies between predicted and observed values appear to be caused by a combination of radionuclide fractionation, ground roughness and instrument self-shielding, and gradient effects. Fractionation effects can cause a difference of a factor of five in the normalization factors for surface and cratering bursts, allowing about 50% reduction in radiation due to ground roughness and instrument self-shielding. Ionization-chamber measurements on field-collected samples are correlated with their degree of fractionation in this report, and a reasonable correspondence between the ionization-chamber readings and the exposure rates measured in the field is established.

Book Description
Radiation Dosimetry, Second Edition, VOLUME III: Sources, Fields, Measurements, and Applications covers the significant aspects of radiation dosimetry. The book discusses dosimetry relating to x rays and teleisotope gamma rays, discrete and distributed alpha-, beta-, and gamma-ray sources, electron beams, and heavy charged particle beams. The text also describes dosimetry relating to reactors, neutron and mixed n-gamma fields, neutrons from accelerators and radioactive sources, initial and residual ionizing radiation from nuclear weapons, natural and man-made background radiation, radiation in space, ultra-high energy radiation, and uncommon types of particles. Dosimetry relating to health physics, diobiology, radiotherapy, implant and intracavitary therapy, ""transition-zones"" (especially at bone-tissue interfaces), and radiation processing is also considered. Physicists, biophysicists, and people involved in radiological science will find the book invaluable.

Book Description
Progress in Nuclear Energy, Volume 5 covers the significant advances in several aspects of nuclear energy field. This book is composed six chapters that describe the progress in nuclear and gas-cooled reactors. The introductory chapter deals with the development and evolution of decay heat estimates and decay heat Standards, and illustrates the use of these estimates through comparison of both the actinide and fission product decay heat levels from typical fuel samples in a variety of reactor systems. The succeeding chapters present different practical methods for handling resonance absorption problem in the case of thermal reactor lattices and review the physics of the different noise phenomena. These topics are followed by discussions of the developed methodology for the description of breeding, conversion, long-term fuel logistics, and related subjects derived from the detailed mathematical description of the fuel cycle. The concluding chapters consider the historical development of heat transfer surfaces for gas-cooled reactors. These chapters also provide a complete set of differential nuclear data on the three technologically important americium isotopes, 241Am, 242Am, and 243Am, suitable for incorporation into the computer-based U.K. Nuclear Data Library. This book will prove useful to nuclear physicists and nuclear energy scientists and researchers.
