This book was released on 1957 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Present chemical techniques for analyzing minute amounts of beryllium are involved and quite time consuming. A method has been developed, utilizing the yield of neutrons and gamma rays fromn Be/sup 9/ under alpha particle bombardment. Samples of air-borne beryllium dust collected on filter paper are exposed to Po/sup 210/ alpha particles and can be analyzed in a matter of minutes. A 3 x 3 inch NaI(Tl) crystal and low voltage discriminator are used to detect the gamma ray yield (4.45 Mev). This yield has been correlated with the beryllium content of filter paper down to ~0.2 mu g. This technique should greatiy facilitate the evaluation of industrial beryllium dust hazards. (auth).

This book was released on 2007-11-10 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beryllium is an important metal that is used in a number of industries-including the defense, aerospace, automotive, medical, and electronics industries-because of its exceptional strength, stability, and heat-absorbing capability. It is found in a variety of technologies, including nuclear devices, satellite systems, missile systems, radar systems, bushings and bearings in aircraft and heavy machinery, x-ray machines used for mammography, cellular telephone components, computer components, and connectors for fiber optics. To help determine the steps necessary to protect its workforce from the adverse effects of exposure to beryllium used in military aerospace applications, the U.S. Air Force requested that the National Research Council's Committee on Toxicology (COT) conduct an independent evaluation of the scientific literature on beryllium, provide risk estimates for cancer and noncancer health end points, and make recommendations about specific tests for surveillance and biomonitoring of workers. The request specified that two reports be produced to accomplish those tasks. The first is to provide a review of the scientific literature on beryllium, and the second will expand more critically on the review in considering the maximum chronic inhalation exposure levels that are unlikely to produce adverse health effects, in estimating carcinogenic risks, and in providing guidance on testing methods for surveillance and monitoring of worker populations and other specific issues detailed in the statement of task. In response to the U.S. Air Force request, COT convened the Committee on Beryllium Alloy Exposures, which prepared this first report. Health Effects of Beryllium Exposure : A Literature Review identifies the available toxicologic, epidemiologic, and other literature on beryllium that is most relevant for addressing the statement of task, focusing primarily on beryllium sensitization, CBD, and cancer.

Download or read book Beryllium Chemistry and Processing written by Kenneth A. Walsh and published by ASM International. This book was released on 2009-01-01 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces beryllium; its history, its chemical, mechanical, and physical properties including nuclear properties. The 29 chapters include the mineralogy of beryllium and the preferred global sources of ore bodies. The identification and specifics of the industrial metallurgical processes used to form oxide from the ore and then metal from the oxide are thoroughly described. The special features of beryllium chemistry are introduced, including analytical chemical practices. Beryllium compounds of industrial interest are identified and discussed. Alloying, casting, powder processing, forming, metal removal, joining and other manufacturing processes are covered. The effect of composition and process on the mechanical and physical properties of beryllium alloys assists the reader in material selection. The physical metallurgy chapter brings conformity between chemical and physical metallurgical processing of beryllium, metal, alloys, and compounds. The environmental degradation of beryllium and its alloys both in aqueous and high temperature condition are presented. The health and environmental issues are thoroughly presented the current requirements and established practices for handling beryllium in the workplace are available. A thorough list of references will assist the user of this book.

Available in PDF, EPUB and Kindle. Book excerpt: Elemental Analysis by Particle Accelerators describes the theory, methodology, and applications for a wide variety of sensitive, non-destructive methods of analysis capable of both high selectivity and multielemental determinations. Specific methods discussed include radioactive methods, particle backscatter analysis, recoil techniques, and nuclear reaction analysis. The use of multielemental PIXE and PIGME analyses of "real world" thick samples in environmental studies, trace element applications in biology, and provenance studies in archaeology are also covered. The book is a useful reference for practicing specialists and an essential text for students.

This book was released on 1995-05-12 with total page 988 pages. Available in PDF, EPUB and Kindle. Book excerpt: People are increasingly concerned about potential environmental health hazards and often ask their physicians questions such as: "Is the tap water safe to drink?" "Is it safe to live near power lines?" Unfortunately, physicians often lack the information and training related to environmental health risks needed to answer such questions. This book discusses six competency based learning objectives for all medical school students, discusses the relevance of environmental health to specific courses and clerkships, and demonstrates how to integrate environmental health into the curriculum through published case studies, some of which are included in one of the book's three appendices. Also included is a guide on where to obtain additional information for treatment, referral, and follow-up for diseases with possible environmental and/or occupational origins.
