Book excerpt: In addition to the gamma ray highintensity dosimetry systems discussed in Nucleonics in October, 1959, several special systems have been utilized by this laboratory in studying radiation effects on materials. A few of these systems are discussed below in the belief that they offer certain advantages in cost or performance and may be of interest to other workers in the field. Since almost any material that exhibits a measureable and reproducible change in physical or chemical properties can be used as a dosimeter, the usefulness of such systems depends on a thorough knowledge of these changes. The foremost requirement, that property changes be accurately measureable, limits their usefulness to limited regions of integrated dose. The requirements for approximating the energy sensitivity, volume, and density of the test materials must also be considered when the energy spectra of the source is unknown or when self-absorption characteristics of the material sample are believed significant. In addition to using dosimetry that approximates the test materials in effective atomic number and sample self-absorption characteristics, more standard techniques such as graphite ion chambers and ferrous-ferric chemical dosimeters are used for comparison with other facility results when possible. At high dose rates or high total dose applications only a few satisfactory systems are available. The use of more than one system is of value for reliability as well as for diagnosis of dose rate and energy sensitivity effects which may influence results obtained with the test material. Integrated dose systems generally involve measurement of some chemical change in a material and are most useful in performing two functions. The first is as a monitor of the total radiation received. This is particularly valuable in sources having a rapidly changing dose rate, especially when the dosimeter system is chosen to have a spectral response similar to the test specimen. The other function is as an absolute calibration of dose or dose rate.

Available in PDF, EPUB and Kindle. Book excerpt: Design, construction, and testing of an integrating gamma-ray dosimeter for high dose rates are discussed. The sensor is a silicon surface-barrier detector operating as a current device. The detector output current is integrated on a capacitor. When the voltage on the capacitor rises to a predetermined level corresponding to 10 rad-equivalent-air of gamma-ray dose, the capacitor is discharged and the instrument produces an output pulse to signal the event. The number of output pulses indicates integrated dose, and the pulse repetition rate indicates dose rate. The detector proper is cooled with a thermoelectric cooler to minimize and stabilize leakage current. The instrument is designed for operation in the dose-rate range of 10 to 100,000 rad-equivalent-air per second. The detector is constructed to make it function as a Bragg-Gray device over the gamma-ray energy range of 80 kev to 12 Mev. The detector is reasonably isotropic; cumulative errors due to all causes are less than plus or minus 30%. The electronics are insensitive to gamma-radiation transients for dose rates as high as 1,000,000 rad per second. Results of tests with radioactive sources, a fast-burst reactor, and bremsstrahlung pulses are given. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Dosimetry of Ionizing Radiation, Volume II, attempts to fill the need for updated reference material on the field of radiation dosimetry. This book presents some broad topics in dosimetry and a variety of radiation dosimetry instrumentation and its application. The book opens with a chapter that extends and applies the concepts of microdosimetry to biological systems. This is followed by separate chapters on the state-of-the-art equipment and techniques used to determine neutron spectra; studies to determine recombination effects in ionization chambers exposed to high-intensity pulsed radiation; advances in water and polystyrene calorimetry; and beta-photon dosimetry for radiation protection. This book is clearly a valuable collection of work by outstanding authorities in their individual fields. It has an international flavor, with authors from England, Canada, and the United States. The quality of the work is equal to the best of what has been published in the past.

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.
