Download or read book Preparation and Validation of Gross Alpha written by and published by . This book was released on 1997 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: A set of water and filter samples have been incorporated into the existing Environmental Measurements Laboratory's (EML) Quality Assessment Program (QAP) for gross alpha/beta determinations by participating DOE laboratories. The participating laboratories are evaluated by comparing their results with the EML value. The preferred EML method for measuring water and filter samples, described in this report, uses gas flow proportional counters with 2 in. detectors. Procedures for sample preparation, quality control and instrument calibration are presented. Liquid scintillation (LS) counting is an alternative technique that is suitable for quantifying both the alpha (241Am, 23°Th and 238Pu) and beta (9°Sr/9°Y) activity concentrations in the solutions used to prepare the QAP water and air filter samples. Three LS counting techniques (Cerenkov, dual dpm and full spectrum analysis) are compared. These techniques may be used to validate the activity concentrations of each component in the alpha/beta solution before the QAP samples are actually prepared.

Book excerpt: A set of water and filter samples have been incorporated into the existing Environmental Measurements Laboratory's (EML) Quality Assessment Program (QAP) for gross alpha/beta determinations by participating DOE laboratories. The participating laboratories are evaluated by comparing their results with the "EML value". The preferred EML method for measuring water and filter samples, described in this report, uses gas flow proportional counters with 2 in. detectors. Procedures for sample preparation, quality control and instrument calibration are presented. Liquid scintillation (LS) counting is an alternative technique that is suitable for quantifying both the alpha (241Am, 230Th and 238Pu) and beta (90Sr/90Y) activity concentrations in the solutions used to prepare the QAP water and air filter samples. Three LS counting techniques (Cerenkov, dual dpm and full spectrum analysis) are compared. These techniques may be used to validate the activity concentrations of each component in the alpha/beta solution before the QAP samples are actually prepared.

This book was released on 2012-12-06 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: NATO Advanced Research Workshop "Environmental Protection Against Radioactive Pollution" was held in Almaty on September 16-19, 2002. Experts from Azerbaijan, Denmark, Hungary, Kazakhstan, Kyrgyzstan, Norway, Russia, Tajikistan, Turkey, Ukraine, USA, Uzbekistan and the IAEA have participated and made presentations. The Workshop was organized parallel to the “2nd Eurasia Conference on Nuclear Science and its Application” held in Almaty on September 16-19, 2002 that was organized by Institute of Nuclear Physics of Kazakhstan with Turkish Atomic Energy Authority and National Academy of Science of Azerbaijan, National Academy of Science of Kyrgyzstan, Institute of Nuclear Physics of Uzbekistan. So, the number of participants for the Workshop was rather high. The NATO Advanced Research Workshop generated important interactions and provided a mechanism for scientists of different nations and of varied disciplines to discuss challenges that confront many countries around the world. The reports presented at the Workshop were published in this NATO Science Series. The main directions of the presented reports were as follows; General estimation of the radioactive contamination of the territories and radiation hazardous objects, including former military test sites, areas influenced due to Chernobly and Mayak accidents, and territories of oil fields; Techniques and procedures of radioecological monitoring; Techniques of determination of radionuclide concentrations and its species in the environment.

Download or read book Strategy and Methodology for Radioactive Waste Characterization written by International Atomic Energy Agency and published by IAEA. 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.
