Available in PDF, EPUB and Kindle. Book excerpt: The angular flux spectrum was measured in a 43 cm sphere filled with the mixture ZrH1.9O0.3Fe0.1A10.05B0.01' representing the approximate homogenized TRIGA reactor core composition (without uranium, and with boron added for thermal neutron absorption). The sphere was reflected with 5.08 cm of water. A 7.6 cm diameter depleted uranium target embedded at the center, excited by a 20 nsec pulsed electron beam for a Linac, was the neutron source for the time-of-flight experiment (50 meter flight distance). Detectors were a 5 by 5 cm liquid scintillator for spectra from 0.4-14 MeV, and a boron capture gamma ray detector for 0.1-0.5 MeV. Measurements were made at 7.6 cm penetration (0 and 51 degrees to the radius vector), at the core-reflector interface, and at the surface of the reflector (0 and 46 degrees). Calculations of the spectrum in the experimental assembly were made with the GAPLSN S sub n code in S8, with 20-group P3 cross sections from the GAM-II code. Comparisons between calculations and experiment were made to decide on the angular mesh, order of anisotropic scattering approximation, energy grouping, and cross sections for a similar calculation of the critical TRIGA reactor spectrum. Results of the calculated cylindrical geometry, P3, S8 angular flux spectrum and total leakage spectrum at the surface of the reflector are tabulated. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The TRIGA Mark II research reactor has a flux spectrum with a predominance of thermal neutrons. While most research can be conducted using this thermal neutron flux, an exclusively fast neutron flux is preferred for some experiments, such as radiation damage studies. Although fast neutron flux spectrums are available using fast reactors or neutron generators, only a few fast reactors are currently in operation and neutron generators tend to have low fluxes. As a result, this report evaluated the possibility of generating a fast neutron flux spectrum in a thermal reactor through the use of an irradiator consisting of layers of uranium, boron, and cadmium. Simulations using Monte Carlo N-Particle Code (MCNP) determined that thin layers of these materials in an irradiator inserted into the 3-Element Facility of the UT-Austin TRIGA reactor will generate a fast neutron flux spectrum with negligible thermal flux and where over 91% of the total flux consists of neutrons with energy greater than 10 keV. Further research is recommended to calculate heat dissipation and to determine the reactivity worth of the irradiator

This book was released on 1966 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was made of a series of pulse exposures of the monkey using a pulsing TRIGA reactor. The reported doses are based on the kerma calculated from threshold foil data for fast neutrons and the gamma exposure determined by silver activated glass rods. These values were compared with extrapolated (by monitoring sulfur) values determined using tissue equivalent ionization chambers for total dose, a Hurst proportional counter for fast neutron dose, and a graphite - CO2 ionization chamber and a tetrachloroethylene chemical dosimeter for gamma dose.

Available in PDF, EPUB and Kindle. Book excerpt: Radiation Research, A Twentieth-Century Perspective, Volume I: Congress Abstracts is a collection of abstracts presented at the Ninth International Congress of Radiation Research convened in Toronto, Canada, organized by the Radiation Research Society and the North American Hyperthermia Group at the invitation of the International Association of Radiation Research. The Toronto venue for this congress recognizes a major role by Canadian scientists in the field of radiation research and also the strong participation of Canadian scientists in the North American Radiation Research Society. Original science is shared at these Congresses through Congress lectures, symposia presentations, and proffered papers. The Congress Board of Directors adopted a proposal that all abstracts of scientific presentations should become a permanent record of the official proceedings of the Congress. In a manner somewhat analogous to the Canadian postal code system, each abstract in this volume is identified at the top left hand corner by a code consisting of both letters and numbers printed on three lines. Line one consists of one letter and two numbers that uniquely identify each scientific event. The second line consists of a double digit number that designates the sequence of presentation within the specific scientific event. The third line consists of a double letter code in which the first letter indicates the day of the week on which abstract material is presented and/or discussed, and the second letter indicates a morning or afternoon session.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
