This book was released on 1988-02-01 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes hazards from radon progeny and other alpha-emitters that humans may inhale or ingest from their environment. In their analysis, the authors summarize in one document clinical and epidemiological evidence, the results of animal studies, research on alpha-particle damage at the cellular level, metabolic pathways for internal alpha-emitters, dosimetry and microdosimetry of radionuclides deposited in specific tissues, and the chemical toxicity of some low-specific-activity alpha-emitters. Techniques for estimating the risks to humans posed by radon and other internally deposited alpha-emitters are offered, along with a discussion of formulas, models, methods, and the level of uncertainty inherent in the risk estimates.

This book was released on 1995-07-17 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades, public concern over exposure to ionizing radiation has increased. This concern has manifested itself in different ways depending on the perception of risk to different individuals and different groups and the circumstances of their exposure. One such group are those U.S. servicemen (the "Atomic Veterans" who participated in the atmospheric testing of nuclear weapons at the Nevada Test Site or in the Pacific Proving Grounds, who served with occupation forces in or near Hiroshima and Nagasaki, or who were prisoners of war in or near those cities at the time of, or shortly after, the atomic bombings. This book addresses the feasibility of conducting an epidemiologic study to determine if there is an increased risk of adverse reproductive outcomes in the spouses, children, and grandchildren of the Atomic Veterans.

Available in PDF, EPUB and Kindle. Book excerpt: In this work the photographic emulsion technique has been applied to the study of the long range particles given off during neutron irradiation of uranium. Alvarez first observed these particles with an ion chamber and linear amplifier. Segre, et al (LA-87) studied these particles with an ion chamber which gave coincidences between these particles and fission. They found them to be coincident with fission within the time constant of their circuit (approx 5u sec). They were also able to identify these particles as alpha particles from the density of ionization near the end of the tracks. Hughes has observed a number of these alpha particles in the cloud chamber, but his setup did not permit him to observe the associated fission track. The cloud chamber or photographic emulsion technique permits information to be obtained about the alpha particles and their association with the fission process that cannot be got by the ion chamber method. The photographic emulsion technique has been used in this case because it lends itself very well to a study of rare events of this type.

Available in PDF, EPUB and Kindle. Book excerpt: Scientific Study from the year 2019 in the subject Physics - Nuclear Physics, Molecular Physics, Solid State Physics, grade: 0.82, University of Manchester (The University of Manchester), language: English, abstract: Alpha particles, or Helium nuclei, are projected by a radioactive isotope source into a vacuum chamber filled by varying thicknesses of either metallic foils (aluminium, nickel) or gases (helium, nitrogen, argon). A Silicon detector, placed at the opposite end of the chamber, detects the final energies of the alpha particles as they penetrate through the media. It is theorised by the Bethe-Bloch equation that the greater the thickness of the medium in the vacuum chamber, the lower the final energies. Through comparison between the Bethe-Bloch equation and experimental data, the ionisation values for the various elements used can be found. Our preliminary results for one such element, aluminium, demonstrate an ionisation value of I=141.2eV.

Download or read book Handbook of Radioactivity Analysis written by Michael F. L'Annunziata and published by Elsevier. This book was released on 2012-12-02 with total page 810 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Radioactivity Analysis is written by experts in the measurement of radioactivity. The book describes the broad scope of analytical methods available and instructs the reader on how to select the proper technique. It is intended as a practical manual for research which requires the accurate measurement of radioactivity at all levels, from the low levels encountered in the environment to the high levels measured in radioisotope research. This book contains sample preparation procedures, recommendations on steps to follow, necessary calculations, computer controlled analysis, and high sample throughput techniques. Each chapter includes practical techniques for application to nuclear safety, nuclear safeguards, environmental analysis, weapons disarmament, and assays required for research in biomedicine and agriculture. The fundamentals of radioactivity properties, radionuclide decay, and methods of detection are included to provide the basis for a thorough understanding of the analytical procedures described in the book. Therefore, the Handbook can also be used as a teaching text. Includes sample preparation techniques for matrices such as soil, air, plant, water, animal tissue, and surface swipes Provides procedures and guidelines for the analysis of commonly encountered na
