Book Description
Neutron Activation Analysis (NAA) is the most common technique used in research reactors worldwide. The IAEA aims to enhance quality assurance in NAA laboratories by supporting annual proficiency testing, by developing and offering relevant e-learning as well as specialized publications. This publication, which is based on the most up to date relevant ISO guides and international practices, provides practical guidance on quality assurance (QA) and quality control (QC) in NAA laboratories. It is intended to be used in the day-to-day work of NAA at research reactors. Potential sources of errors and associated QA/QC actions are detailed for all main areas of NAA practice. Easy to use tables are provided, intended for direct reference in the laboratory.

Book Description
The IAEA supports its Member States to increase the utilization of their research reactors. Small and medium sized reactors are mostly used for neutron activation analysis (NAA). Although the markets for NAA laboratories have been identified, demonstration of valid analytical results and organizational quality of the work process are preconditions for expanding the stakeholder community, particularly in commercial routine application of this powerful technique. The IAEA has implemented a new mechanism for supporting NAA laboratories in demonstrating their analytical performance by participation in proficiency testing schemes by interlaboratory comparison. This activity makes possible the identification of deviations and non-conformities, their causes and the process to implement effective approaches to eliminate them. Over 30 laboratories participated between 2010 and 2015 in consecutive proficiency tests organized by the IAEA in conjunction with the Wageningen Evaluating Programmes for Analytical Laboratories (WEPAL) to assess their analytical performances. This publication reports the findings and includes lessons learned of this activity. An attached CD-ROM contains many individual participating laboratory papers sharing their individual results and experience gained through this participation.

Book Description
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.

Book Description
"Neutron activation analysis (NAA) is a powerful technique for determining bulk composition of major and trace elements. Automation may contribute significantly to keep NAA competitive for end-users. It provides opportunities for a larger analytical capacity and a shorter overall turnaround time if large series of samples have to be analysed. This publication documents and disseminates the expertise generated on automation in NAA during a coordinated research project (CRP). The CRP participants presented different cost-effective designs of sample changers for gamma-ray spectrometry as well as irradiation devices, and were able to construct and successfully test these systems. They also implemented, expanded and improved quality control and quality assurance as crossƯcutting topical area of their automated NAA procedures. The publication serves as a reference of interest to NAA practitioners, experts, and research reactor personnel, but also to various stakeholders and users interested in basic research and/or services provided by NAA. The individual country reports are available on the CD-ROM attached to this publication."--Publisher's description

Book Description
By presenting background information on the selection and application of biochemical tests in safety assessment studies, this text seeks to provide a basis for improving the knowledge required to interpret data from toxicological studies. In addition to chapters which discuss the assessment of specific organ toxicity (such as the liver, kidney and thyroid), the book also covers pre-analytical variables, regulatory requirements and statistical approaches, and highlights some of the major differences between man and different laboratory animals. The editor and contributor are all members of the Animal Clinical Chemistry Association, a group formed to advance the science of animal clinical chemistry in safety evaluation, toxicology and veterinary science.

Book Description
Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
