Book Description
The fast neutron spectrum of the Coupled Fast Reactivity Measurements Facility (CFRMF) at the Idaho National Engineering Laboratory (INEL) is being used to study and standardize fast reactor neutron dosimetry materials and methods. The CFRMF has been designated a ''benchmark experiment'' to test the cross section data of dosimetry materials as well as other materials used and produced in fast reactors. Information about the neutron energy spectrum of the CFRMF is presented. (auth).

Book Description
The Coupled Fast Reactivity Measurements Facility (CFRMF) has been used for several years in fast neutron dosimetry studies. These studies have included the neutron energy spectrum, dosimetry cross-sections, fission product yields, dosimeter calibration and testing, fission rate measurements, detector calibrations, helium production cross-sections, flux distributions and various other integral cross-sections. The CFRMF neutron field has been established as a dosimetry benchmark neutron field and has been involved extensively in inter-laboratory reaction rate measurements testing programs. The available and reproducible neutron flux densities of up to 8.6 x 1011 n/cm2/sec make it useful for dosimetry testing more closely related to power and test reactor fluences. Methods and equipment have been developed to provide the testing of dosimeters and for producing irradiated dosimeter standards. The production of these standards and the testing of dosimeters are vital to the dosimetry of test and power reactors to assure that radiation measurements are producing the correct results.

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.

Book Description
Dosimetry measurements and calibrations have been made at the University of Washington's Fast Neutron Medical Research Facility. The facility is designed to deliver localized neutron doses of a few rads to the testes of volunteer subjects at 2.5 MeV and 14 MeV. Dose measurements were based on the use of tissue equivalent ion chambers. Dosimetry and shielding measurements show that doses accurate to +-10% can be delivered to the volume of interest while maintaining safe dose levels outside the shield and to other portions of the subject. 10 references, 9 figures, 3 tables.
