Book excerpt: There is a need for fast, reliable methods for the determination of actinides and Sr-89/90 analysis on environmental and bioassay samples in response to an emergency radiological incident. The SRS (Savannah River Site) Environmental Bioassay Laboratory participated in the National Institute of Standards and Technology Radiochemistry Intercomparison Program (NRIP-06) and analyzed water and urine samples within 8 hours of receipt. The SRS Environmental Laboratory was the only lab that participated in the program that analyzed these samples for both actinides and Sr-89/90 within the requested 8 hour turnaround time. A new, rapid actinide and strontium 89/90 separation method was used for both urine and water samples. This method uses stacked TEVA Resin{reg_sign}, TRU Resin{reg_sign} and Sr-Resin{reg_sign} cartridges from Eichrom Technologies (Darien, IL, USA) that allows the rapid separation of plutonium (Pu), neptunium (Np), uranium (U), and americium (Am), curium (Cm) and thorium (Th) using a single multi-stage column combined with alpha spectrometry. By using vacuum box cartridge technology and stacked cartridges with rapid flow rates, sample preparation time was minimized. This paper discusses the technology and conditions employed for both water and urine samples and presents the SRS performance data on the NRIP-06 samples.

Available in PDF, EPUB and Kindle. Book excerpt: The Savannah River Site Environmental Bioassay Lab participated in the 2008 NRIP Emergency Response program administered by the National Institute for Standards and Technology (NIST) in May, 2008. A new rapid column separation method was used for analysis of actinides and 9°Sr the NRIP 2008 emergency water and urine samples. Significant method improvements were applied to reduce analytical times. As a result, much faster analysis times were achieved, less than 3 hours for determination of 9°Sr and 3-4 hours for actinides. This represents a 25%-33% improvement in analysis times from NRIP 2007 and a ≈100% improvement compared to NRIP 2006 report times. Column flow rates were increased by a factor of two, with no significant adverse impact on the method performance. Larger sample aliquots, shorter count times, faster cerium fluoride microprecipitation and streamlined calcium phosphate precipitation were also employed. Based on initial feedback from NIST, the SRS Environmental Bioassay Lab had the most rapid analysis times for actinides and 9°Sr analyses for NRIP 2008 emergency urine samples. High levels of potential matrix interferences may be present in emergency samples and rugged methods are essential. Extremely high levels of 21°Po were found to have an adverse effect on the uranium results for the NRIP-08 urine samples, while uranium results for NRIP-08 water samples were not affected. This problem, which was not observed for NRIP-06 or NRIP-07 urine samples, was resolved by using an enhanced 21°Po removal step, which will be described.

Book excerpt: The Savannah River Site Environmental Bioassay Lab participated in the 2007 NRIP Emergency Response program administered by the National Institute for Standards and Technology (NIST) in May, 2007. A new rapid column separation method was applied directly to the NRIP 2007 emergency urine samples, with only minimal sample preparation to reduce preparation time. Calcium phosphate precipitation, previously used to pre-concentrate actinides and Sr-90 in NRIP 2006 urine and water samples, was not used for the NRIP 2007 urine samples. Instead, the raw urine was acidified and passed directly through the stacked resin columns (TEVA+TRU+SR Resins) to separate the actinides and strontium from the NRIP urine samples more quickly. This improvement reduced sample preparation time for the NRIP 2007 emergency urine analyses significantly. This approach works well for small volume urine samples expected during an emergency response event. Based on initial feedback from NIST, the SRS Environmental Bioassay Lab had the most rapid analysis times for actinides and strontium-90 analyses for NRIP 2007 urine samples.

Download or read book Rapid Health Assessment Protocols for Emergencies written by World Health Organization and published by World Health Organization. This book was released on 1999 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a collection of ten protocols for conducting rapid health assessments in the immediate aftermath of different types of emergencies. Noting the vital importance of rapid and accurate information in the earliest stage of an emergency, the protocols respond to the urgent need for common standardized technical tools for assessing damage, gauging health risks, and gathering the information immediately needed by decision-makers at the national and international level. The protocols were prepared by WHO in collaboration with a large number of international agencies and experts with broad experience in the field of emergency management. Although all protocols follow a common format, each is specific to the circumstances, potential hazards, and immediate information needs that characterize a distinct type of emergency. Emphasis is placed on the exact information needed, the best sources of data and methods for rapid collection, and the specific questions that need to be answered in order to draw initial conclusions and direct immediate actions. Although the advantages of using experienced assessments teams are stressed, the book also explains how the protocols can be used to train general health workers as part of emergency preparedness. The book opens with an introductory protocol covering the aims and methods, responsibilities, complexities, and inherent difficulties of rapid health assessments. Addressed to health authorities as well as assessment teams, the chapter also includes abundant advice on preparedness for emergencies. Details range from the comparative need for speed in different types of emergencies, through a suggested format for presenting the results of assessments, to a list of common logistic, organizational, and technical errors. Advice on the best working practices, including ways to avoid being an "emergency tourist", is also provided. Against this background, the additional nine protocols are presented according to a common format which covers the purpose of the assessment, preparedness, the steps to follow during the assessment, assessing the impact on health, assessing local response capacity and immediate needs, and presenting results. A general protocol on epidemics of infectious origin is followed by protocols specific to meningitis outbreaks, outbreaks of viral haemorrhagic fever, including yellow fever, and outbreaks of acute diarrhoeal disease, with information specific to dysentery and cholera. Sudden-impact natural disasters are covered in the next protocol, which includes a day-by-day list of information priorities for different stages of the disaster. A protocol dealing with sudden population displacements offers guidelines for conducting rapid health assessments in all emergencies caused by sudden displacement of refugees or population groups within a country. Included are a sample checklist for rapid assessments and a sample form for weekly reports on morbidity and mortality. Subsequent protocols deal with the special situations of nutritional emergencies and chemical emergencies, including those caused by food contaminated with chemicals or toxins. The final protocol addresses the difficult task of conducting assessments in complex emergencies in which the cause of the emergency, as well as the assistance to the afflicted, is complicated by intense levels of political considerations. The protocol includes a form which has recently been used for rapid health assessment at local level in Bosnia and Herzegovnia. The book concludes with a brief summary of survey techniques, followed by a tabular presentation of reference values for assessing needs, hazards, and logistic requirements in developing countries.

This book was released on 2020-02-20 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
