Book Description
Americium is precipitated with bismuth phosphate from a nitric acid- digested urine sample. The bismuth phosphate is wet-ashed, dissolved in 6N--HCl, and the americium is precipitated with lamthanum fluoride. The lanthanum fluoride is metathesized to the hydroxide, and the precipitate is dissolved in 2N- nitric acid. Removal of concurrently metabolized plutonium is accomplished by liquid-liquid extraction of the nitric acid soiution with 0.1-M di(2- ethylhexyl)phosphoric acid (D2EIIPA) in chloroform. The purified americium is carried on lanthanum fluoride. The precipitate is slurried onto a stainless steel plamchet and counted in a low-background proportional alpha counter. The method is effective for quantitative separation from plutonium and uranium. Quantities of the order of 0.5 dpm of americium cam be detected in a urine sample. (auth).

Book Description
The updated and much expanded 3e of the Handbook of Radioactivity Analysis is an authoritative reference providing the principles, practical techniques, and procedures for the accurate measurement of radioactivity from the very low levels encountered in the environment to higher levels measured in radioisotope research, clinical laboratories, biological sciences, radionuclide standardization, nuclear medicine, nuclear power, and fuel cycle facilities and in the implementation of nuclear forensic analysis and nuclear safeguards. The book describes the basic principles of radiation detection and measurement and the preparation of samples from a wide variety of matrices, assists the investigator or technician in the selection and use of appropriate radiation detectors, and presents state-of-the-art methods of analysis. Fundamentals of radiation properties, radionuclide decay, the calculations involved, and methods of detection provide the basis for a thorough understanding of the analytical procedures. The Handbook of Radioactivity Analysis, 3e, is suitable as a teaching text for university and professional training courses. The only comprehensive reference that describes the principles of detection and practical applications of every type of radioactivity detector currently used. The new 3e is broader in scope, with revised and expanded chapters, new authors, and seven new chapters on Alpha Spectrometry, Radionuclide Standardization, Radioactive Aerosol Measurements, Environmental Radioactivity Monitoring, Marine Radioactivity Analysis, Nuclear Forensic Analysis and Analytical Techniques in Nuclear Safeguards Discusses in detail the principles, theory and practice applied to all types of radiation detection and measurement, making it useful for both teaching and research

Book Description
The current methods used by the tissue analysis program at LASL for the determination of americium and plutonium in autopsy tissue are described. Problems affecting radiochemical yield are discussed. Included are problems associated with sample preparation, separation of plutonium from large amounts of bone ash, and reagent contamination. The average 242Pu tracer yield for 1800 Pu determinations is 78 +- 12%. The average 242Am tracer yield is 85 +- 7% for 40 determinations.
