Book Description
A proposed neutron monitoring instruments consists of a Li6I crystal centered in 3-in.-, 10-in.-, and 18-in.- diameter polyethylene spheres. The polyethylene moderates neutrons so that they may be counted as the result of the (n, [alpha]) reaction in the crystal. Transport theory calculations of sphere counting efficiencies made use of 21 group corss sections from thermal energies to 192 MeV. Results show that the monitoring system is effective for particle accelerators where neutrons up to 100 MeV in energy would be found.

Book Description
A continuation of the treatise The Dosimetry of Ionizing Radiation, Volume III builds upon the foundations of Volumes I and II and the tradition of the preceeding treatise Radiation Dosimetry. Volume III contains three comprehensive chapters on the applications of radiation dosimetry in particular research and medical settings, a chapter on unique and useful detectors, and two chapters on Monte Carlo techniques and their applications.

Book Description
Measurements of neutron spectra with nuclear emulsion at various distances from a 14 MeV neutron source were made at the Nevada Test Site during Operation HENRE. These measurements and supplementary ones made using the neutron flux integrator developed at the Lawrence Radiation Laboratory, and a version of Bonner's spectrometer, are compared with theoretical calculations. Overall agreement was found to be good.

Book Description
Radiation Dosimetry, Supplement 1: Topics in Radiation Dosimetry covers instruments and techniques in dealing with special dosimetry problems. The book discusses thermoluminescence dosimetry in archeological dating; dosimetric applications of track etching; vacuum chambers of radiation measurement. The text also describes wall-less detectors in microdosimetry; dosimetry of low-energy X-rays; and the theory and general applicability of the gamma-ray theory of track effects to various systems. Dose equivalent determinations in neutron fields by means of moderator techniques; as well as developments in radiophotoluminescence dosimetry are also considered. Physicists, mathematicians, and archeologists will find the book useful.

Book Description
The Committee on Dosimetry for the Radiation Effects Research Foundation (RERF) was set up more than a decade ago at the request of the U.S. Department of Energy. It was charged with monitoring work and experimental results related to the Dosimetry System 1986 (DS86) used by RERF to reconstruct the radiation doses to the survivors in Hiroshima and Nagasaki. At the time it was established, DS86 was believed to be the best available dosimetric system for RERF, but questions have persisted about some features, especially the estimates of neutrons resulting from the Hiroshima bomb. This book describes the current situation, the gamma-ray dosimetry, and such dosimetry issues as thermal-neutron discrepancies between measurement and calculation at various distances in Hiroshima and Nagasaki. It recommends approaches to bring those issues to closure and sets the stage for the recently convened U.S. and Japan Working Groups that will develop a new dosimetry for RERF. The book outlines the changes relating to DS86 in the past 15 years, such as improved numbers that go into, and are part of, more sophisticated calculations for determining the radiations from bombs that reach certain distances in air, and encourages incorporation of the changes into a revised dosimetry system.
