Available in PDF, EPUB and Kindle. Book excerpt: In order to support the many on-going research and programmatic activities at Los Alamos Plutonium and Chemistry and Metallurgy Research (CMR) Facilities in as accurate, efficient, and cost-effective manner possible, every reasonable effort is made to equip the nondestructive assay (NDA) laboratories with the most modern and technologically advanced instrumentation available. Recently, new state-of-the-art tomographic gamma scanner (TGS) instruments were installed to replace aging and outmoded segmented gamma scanner (SGS) instruments. Through the implementation of a translation axis, in addition to the vertical and rotation axes of the SGS, the TGS technique is able to employ axial tomography to determine the spatial distribution and quantity of nuclear material using high-resolution gamma-ray spectroscopy. Because the attenuation matrix and source distributions are known more accurately than with the SGS technology, biases due to matrix and source distributions should be reduced. In principle, a single calibration should suffice for the determination of isotopic mass for a wide range of material and matrix types. A number of questions naturally arise concerning these purported advantages of the TGS. Perhaps the most fundamental of these is to understand how the TGS measurement results compare with those of a typical SGS on the same well-characterized standards differing in matrix and material type. To that end, the TGS operating parameters were optimized to assay 55-gallon drum waste identical to that measured by our SGS. The calibration and measurement results on these standards, placed in typical low-density waste matrices, are presented and discussed. These results should enable more confident use of the TGS as well as point the way toward even more studies to enable more effective employment of the new TGS technology.

Download or read book Bias Investigation of a 55 gallon Drum sized Segmented Gamma Scanner written by and published by . This book was released on 1993 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper addresses a series of studies undertaken while fulfilling the measurement requirements for certification of a 55-gallon drum-sized segmented gamma scanner to be used at the plutonium facility (TA-55) at Los Alamos. These studies were initiated to investigate anomalies seen in the data as well as gain a quantifiable understanding of effects caused by using standards of considerably different geometric proportions than the assay items, oftentimes necessitated due to lack of adequate standards. The first investigation concerned effects caused by items not being exactly centered on the measurement table. The remaining studies involved establishing the magnitude of the bias induced by so-called ''end effects'' as well as by size differences between calibration standards and assay items. In order to unravel the above effects, can and drum parameter files were interchangeably employed in conjunction with comparisons of the instrument calibrations obtained with can-sized standards and 55-gallon drum standards. The paper will discuss the results and the magnitude of the observed effects.
Download or read book Recent Advances in Segmented Gamma Scanner Analysis written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The segmented gamma scanner (SGS) is used in many facilities to assay low-density scrap and waste generated in the facilities. The procedures for using the SGS can cause a negative bias if the sample does not satisfy the assumptions made in the method. Some process samples do not comply with the assumptions. This paper discusses the effect of the presence of lumps on the SGS assay results, describes a method to detect the presence of lumps, and describes an approach to correct for the lumps. Other recent advances in SGS analysis are also discussed.

This book was released on 2013-10-01 with total page 1978 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general theme of MEDICON 2013 is "Research and Development of Technology for Sustainable Healthcare". This decade is being characterized by the appearance and use of emergent technologies under development. This situation has produced a tremendous impact on Medicine and Biology from which it is expected an unparalleled evolution in these disciplines towards novel concept and practices. The consequence will be a significant improvement in health care and well-fare, i.e. the shift from a reactive medicine to a preventive medicine. This shift implies that the citizen will play an important role in the healthcare delivery process, what requires a comprehensive and personalized assistance. In this context, society will meet emerging media, incorporated to all objects, capable of providing a seamless, adaptive, anticipatory, unobtrusive and pervasive assistance. The challenge will be to remove current barriers related to the lack of knowledge required to produce new opportunities for all the society, while new paradigms are created for this inclusive society to be socially and economically sustainable, and respectful with the environment. In this way, these proceedings focus on the convergence of biomedical engineering topics ranging from formalized theory through experimental science and technological development to practical clinical applications.

This book was released on 2007 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade significant progress has been achieved in the development of waste characterization and control procedures and equipment as a direct response to ever-increasing requirements for quality and reliability of information on waste characteristics. Failure in control procedures at any step can have important, adverse consequences and may result in producing waste packages which are not compliant with the waste acceptance criteria for disposal, thereby adversely impacting the repository. The information and guidance included in this publication corresponds to recent achievements and reflects the optimum approaches, thereby reducing the potential for error and enhancing the quality of the end product. -- Publisher's description.
Download or read book Nuclear Cardiac Imaging written by Ami E. Iskandrian and published by Oxford University Press. This book was released on 2008-09-25 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear cardiac imaging is the diagnostic technique of using radiology and chemical markers to track cardiac performance. These imaging studies provide a wide range of information about the heart, including how much the heart contracts, the amount of blood supply to the heart and whether parts of the heart muscle are alive or dead. This is essential information for cardiologists, and nuclear imaging has become an increasingly important part of the cardiologist's armoury of diagnostic techniques. Iskandrian's text has become a leading book in the field and the fourth edition will continue the tradition. The text is updated throughout to reflect the many advances in the field, and, as a new feature, each chapter concludes with a question and answer session on important and difficult clinical issues.
