This book was released on 2010-02-23 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prompt gamma activation analysis (PGAA) is a unique, non-destructive nuclear analytical method with multi-element capabilities. It is most effective if intense neutron beams (especially cold beams) of nuclear reactors are used to induce the prompt gamma radiation. Based largely on the authors' pioneering research in cold neutron PGAA, the handbook describes the methodology in self-contained manner and reviews recent applications. The library of prompt gamma ray data and spectra for all natural elements is a unique aid to the practitioner. The level is understandable by a broad audience, which facilitates teaching and training. The Handbook of Prompt Gamma Activation Analysis is a comprehensive handbook written for those practising the method, wanting to implement it at a reactor facility, or just looking for a powerful non-destructive method of element analysis. The book is also useful for nuclear physics, chemistry and engineering scientists, scholars and graduate students interested in neutron-induced gamma ray spectroscopy and nuclear analytical methods.

Available in PDF, EPUB and Kindle. Book excerpt: Prompt Gamma Neutron Activation Analysis introduces the fundamental principals and the unique characteristics of the gamma-ray activation method together with its applications and limitations. Sample preparation, instruments, shielding and irradiation using prompt gamma-ray activation analysis techniques with various neutron sources are described in detail. The neutron damage to PGAA instruments, particularly the radiation detector, is investigated. The book compares unique features and limitations of PGAA versus conventional NAA methods. Approximately 50 tables help to illustrate and describe these exciting new methods.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A prompt-gamma, neutron-activation analysis facility earlier developed at the Nuclear Science Center of Texas A & M University could not be used successfully to analyze geologic samples due to high detection background, low neutron fluence rate and poor detection equipment . A systematic investigation into the performance capability of a prompt-gamma, neutron activation analysis facility was undertaken in this research project. The facility was reconstructed and used to obtain prompt-gamma spectra of chlorine and cadmium and from the spectra, the net peak area counts for the most intense prompt-gamma-ray energies were obtained. A theoretical model was developed which can predict the net peak area counts expected on these prompt-gamma-ray energies using the thermal neutron fluence rate at the sample position, the absolute efficiency of the detector, and the mass and partial gamma-ray production cross section data for the samples. The experimental and predicted results were compared to establish the performance capability of the reconstructed facility. Good agreements between experimental and predicted results were obtained for chlorine, but results from cadmium showed larger discrepancies due to self-shielding effects. Corrections for self-shielding effects were applied to results from cadmium and the experimental and predicted results were also in good agreement. The satisfactory results indicate that it is possible to implement the prompt-gamma, neutron-activation analysis technique at Beam Port #1 of the Nuclear Science Center Reactor. To be able to obtain excellent results from other samples, improvements in shielding materials to attain a lower detection background and a highly efficient detection system should be incorporated.

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.

Available in PDF, EPUB and Kindle. Book excerpt: After configuring the proper electronic system to be used, the initial observations of the gamma-gamma coincidence approach were presented. These observations included hydrogen peak elimination, background and sum peak elimination, pulse pile up reduction, and two dimensional spectra. Three practical applications of the coincidence counting approach were presented in this work. The first application was performing elemental analysis for a mixture of radioisotopes using Library Least Squares (LLS). The LLS was applied to the coincidence data as well as the normal single detector data. The coincidence results showed to be much closer to the original activity values of the radioisotopes than the singles. In addition, the coincidence approach greatly reduced the background, summing, and pulse pile up effects. The second application was the two dimensional diagonal summing. The main advantages from this application were improving the peak resolution and greatly reducing the background (Compton Continuum). In addition, it was shown that different diagonal sums can be examined by use of the same set of data from the current electronic system (and software). The two dimensional diagonal summing was used for identifying coincidence schemes and for elemental analysis. The obtained spectra showed to be very promising and could be effectively used for these purposes. The third practical application was using a new NaI detector arrangement. The arrangement was designed to deal with the problem of the low detection probability of the high energy gamma rays of interest in the oil well logging industry. This arrangement consisted of two NaI detectors, one of which was a well type. The detectors were designed to fit in each other. Coincidence data were collected using this new arrangement. The results show that this new arrangement enhances the count rate in the coincidence data, thus increasing the Signal to Noise Ratio, as opposed to two separate detector setups. Finally, a Monte.
