Radiation Dosimetry and Spectrometry written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-02 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation experiments flown by the University of San Francisco on the Cosmos 1887 spacecraft were designed to measure the depth dependence of both total dose and heavy particle flux, dose and dose equivalent, down to very thin shielding. Three experiments were flown and were located both inside and outside the Cosmos 1887 spacecraft. Tissue absorbed dose rates of 264 to 0.028 rad d(-1) under shielding of 0.013 to 3.4 g/sq cm of (7)LiF were found outside the spacecraft and 0.025 rad d(-1) inside. Heavy particle fluxes of 3.43 to 1.03 x 10 to the minus 3rd power cm -2 sub s -1 sub sr -1 under shielding of 0.195 to 1.33 g/sq cm plastic were found outside the spacecraft and 4.25 times 10 to the minus 4th power cm -2 sub s -1 sub sr -1 inside (LET infinity H2O greater than or equal to 4 keV/micron m). The corresponding heavy particle dose equivalent rates outside the spacecraft were 30.8 to 19.8 mrem d(-1) and 11.4 mrem d(-1) inside. The large dose and particle fluxes found at small shielding thicknesses emphasize the importance of these and future measurements at low shielding, for predicting radiation effects on space materials and experiments where shielding is minimal and on astronauts during EVA. The Cosmos 1887 mission contained a variety of international radiobiological investigations to which the measurements apply. The high inclination orbit (62 degrees) of this mission provided a radiation environment which is seldom available to U.S. investigators. The radiation measurements will be compared with those of other research groups and also with those performed on the Shuttle, and will be used to refine computer models employed to calculate radiation exposures on other spacecraft, including the Space Station.

Available in PDF, EPUB and Kindle. Book excerpt: A little-known yet critical part of NASA history Life in Space explores the many aspects and outcomes of NASA’s research in life sciences, a little-understood endeavor that has often been overlooked in histories of the space agency. Maura Mackowski details NASA’s work in this field from spectacular promises made during the Reagan era to the major new directions set by George W. Bush’s Vision for Space Exploration in the early twenty-first century. At the first flight of NASA’s space shuttle in 1981, hopes ran high for the shuttle program to achieve its potential of regularly transporting humans, cargo, and scientific experiments between Earth and the International Space Station. Mackowski describes different programs, projects, and policies initiated across NASA centers and headquarters in the following decades to advance research into human safety and habitation, plant and animal biology, and commercial biomaterials. Mackowski illuminates these ventures in fascinating detail by drawing on rare archival sources, oral histories, interviews, and site visits. While highlighting significant achievements and innovations such as space radiation research and the Neurolab Spacelab Mission, Mackowski reveals frustrations—lost opportunities, stagnation, and dead ends—stemming from frequent changes in presidential administrations and policies. For today’s dreams of lunar outposts or long-term spaceflight to become reality, Mackowski argues, a robust program in space life sciences is essential, and the history in this book offers lessons to help prevent leaving more expectations unfulfilled.

Book Synopsis Effects of A-bomb Radiation on the Human Body by : Itsuzō Shigematsu
Download or read book Effects of A-bomb Radiation on the Human Body written by Itsuzō Shigematsu and published by Routledge. This book was released on 1995 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, radiation exposure has become a major issue in various parts of the world as the result of nuclear testing and accidents at nuclear power plants such as Chernobyl. In order to help the victims of such events, the "International Council for the" "Health Care of the Radiation-Exposed" was established. This study by the council provides a comprehensive 47-year review of the known radiation-induced health effects on the survivors of the atomic bomb explosion in Hiroshima, Japan. Included are reports by 39 specialists in the field of radiation medicine encompassing studies on all diseases, cancers, growth and developmental effects associated with radiation exposure. This up-dated information on the medical problems of the A-bomb survivors contributes to a better understanding of radiation-induced disorders in humans.
