Download or read book Fabrication of Intense Neutron Sources for Medical Applications written by and published by . This book was released on 1975 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Simulated sources containing $sup 252$Cf equivalents of 0.1 to 1.0 milligrams were prepared. Samarium was used as the simulant in a modified chemical plating technique similar to that used to prepare palladium-californium oxide cermet for industrial applications. The length of the platinum-10 percent iridium doubly encapsulated source with its protective sheath is 0.545 in. (14.1 mm). Outside dia of the source, including its sheath, is 0.109 in. (2.8 mm). Existing ''Brachytrons'' can accommodate this source form. This capsule system will withstand internal gas pressures from helium due to alpha decay and fission gases from a 1 mg $sup 252$Cf source after ten years if the source is subjected to a maximum temperature of 800$sup 0$C, the theoretical temperature of an accidental fire. Under these conditions the safety factor is 3. The capsule system is being tested with tracer amounts of $sup 252$Cf to ensure that it will withstand adverse service conditions as well as tests specified for Special Form Materials. (auth).

Book excerpt: The design and fabrication of a high-intensity, 14-Mev neutron source which can be operated on a hoist platform on the 1500-ft BREN tower at the Nevada Test Site (NTS) has been determined to be feasible. Utilizing the T(d, n)-4He reaction, the source should be capable of producing, as a minimum, an average intensity of 10-13 neutrons/sec for periods up to 4 hr. The type and placement of power supplies, ion sources, targets, and vacuum equipment have been examined and a preliminary conceptual design completed. Control systems, testing procedures, and construction operations were studied and are presented. It is estimated that the neutron source will cost from 260,000 to 300,000, occupy approximately 400 ft-3, weigh approximately 7.5 tons and require about 10 months to complete.

Download or read book Conceptual Development of Steady State Compact Fusion Neutron Sources written by International Atomic Energy Agency and published by International Atomic Energy Agency. This book was released on 2019-09-24 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusion neutron sources have many important practical uses, including triggering fission reactions, manufacturing medical isotopes, testing materials and components for use in future fusion power reactors, and facilitating the production of various isotopes like tritium. All these applications can be potentially improved by achieving high energy compact fusion neutron sources (CFNSs). The present publication is a compilation of the main results and findings of an IAEA coordinated research project (CRP) on the development of concepts and conceptual designs for both low and high power CFNSs. Through the collaboration of experts in the participating Member States, the results achieved under the project laid the foundation for practical applications of intense fusion neutron sources.

Download or read book Neutron Generators for Analytical Purposes written by International Atomic Energy Agency and published by IAEA Radiation Technology Repo. This book was released on 2012 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication addresses recent developments in neutron generator (NG) technology. It presents information on compact instruments with high neutron yield to be used for neutron activation analysis (NAA) and prompt gamma neutron activation analysis in combination with high count rate spectrometers. Traditional NGs have been shown to be effective for applications including borehole logging, homeland security, nuclear medicine and the on-line analysis of aluminium, coal and cement. Pulsed fast thermal neutron analysis, as well as tagged and timed neutron analysis, are additional techniques which can be applied using NG. Furthermore, NG can effectively be used for elemental analysis and is also effective for analysis of hidden materials by neutron radiography. Useful guidelines for developing NG based research laboratories are also provided in this publication.

Download or read book Californium 252 Isotope for 21st Century Radiotherapy written by J.G. Wierzbicki and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Californium-252 is a neutron emitter with a high specific activity, making it useful in a variety of applications, the most spectacular of which is in brachytherapy for cancer patients. Radiation oncology has exhausted nearly every option for treating radioresistant tumors by photon brachytherapy, and therefore new types of radiation need to be studied to improve the curability of cancer. Audience: Californium brachytherapy is used in only a few radiation therapy centers in the world, so the book will be highly instructive for radiation oncologists, medical physicists and radiobiologists. The nuclear techniques used in clinical applications may also interest nuclear physicists and engineers.

Book excerpt: Californium-252 neutron sources are being prepared to investigate the value of this radionuclide in diagnosing and treating diseases. A source resembling a cell-loaded radium needle was developed for neutron therapy. Since therapy needles are normally implanted in the body, very conservative design criteria were established to prevent leakage of radioactive. Methods are being developed to prepare very intense californium sources that could be used eventually for neutron radiography and for diagnosis by neutron activation analysis. This paper discusses these methods.
