This book discusses space radiation hazards as well as the importance of natural radiations in the processes of biogenesis. Organized into 12 chapters, this book begins with an overview of the fundamental aspects of radiobiology. This text then discusses the theoretical treatments of the chronic radiation response and the applicability of some of its features in extended manned space missions. Other chapters review the literature on models for recovery from radiation damage to some cellular systems. This book discusses as well the effects of radiations on mammals, with emphasis on those effects pertinent to the space-flight situation. The final chapter deals with the safety of nuclear power in space and explains the three types of nuclear devices designed for power production in space. This book is a valuable resource for radiologists, radiobiologists, and radiotherapists.

This book was released on 2012-12-06 with total page 845 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on the proceedings of an Advanced Study Institute (ASI) sponsored by the North Atlantic Treaty Organization (NATO) held October 1987 in Corfu, Greece. The Institute received financial support from the National Aeronautics and Space Administration, U.S.A. Armed Forces Radiobiology Research Institute, U.S.A. Department of Energy, U.S.A. Deutsche Forschungs-und Versuchanstalt fur Luft und Raumfahrt e.v., Kaln, Germany The advent of the shuttle era is providing fresh impetus for large space ventures such as communication centers, solar power stations, astronomical observatories, orbiting factories, and space based radar. Such ventures will rely heavily on an extensive and prolonged human presence in space doing in-orbit construction, maintenance, and opera tion. Among the advantages of location in space are the near zero gravity environment, commanding location, and the reception of solar energy and astronomical signals unattenuated by the atmosphere. Central to long-term manned space missions are the problems associated with the effects of exposure to ionizing radiations on humans. Manned space mis sions in the past have encountered relatively benign radiation environ ments because of their very short duration and orbit configuration. However, crew stay time of up to a year has been recently achieved by the Soviet space program; and Mars missions lasting several years are under serious consideration.

This book was released on 1997-02-27 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA's long-range plans include possible human exploratory missions to the moon and Mars within the next quarter century. Such missions beyond low Earth orbit will expose crews to transient radiation from solar particle events as well as continuous high-energy galactic cosmic rays ranging from energetic protons with low mean linear energy transfer (LET) to nuclei with high atomic numbers, high energies, and high LET. Because the radiation levels in space are high and the missions long, adequate shielding is needed to minimize the deleterious health effects of exposure to radiation. The knowledge base needed to design shielding involves two sets of factors, each with quantitative uncertaintyâ€"the radiation spectra and doses present behind different types of shielding, and the effects of the doses on relevant biological systems. It is only prudent to design shielding that will protect the crew of spacecraft exposed to predicted high, but uncertain, levels of radiation and biological effects. Because of the uncertainties regarding the degree and type of radiation protection needed, a requirement for shielding to protect against large deleterious, but uncertain, biological effects may be imposed, which in turn could result in an unacceptable cost to a mission. It therefore is of interest to reduce these uncertainties in biological effects and shielding requirements for reasons of mission feasibility, safety, and cost.

This book was released on 2012-01-30 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.
Download or read book Advances in Radiation Biology written by John T. Lett and published by Academic Press. This book was released on 2013-10-22 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Radiation Biology, Volume 12, provides an overview of the state of knowledge in the field of radiation biology. Environmental matters are continuing to produce surprises and remain sources of concern. The safe disposal of radioactive waste still is a major problem facing the nuclear power industry. A possible solution is discussed here. New information about the survivors from radiation exposure at Hiroshima and Nagasaki has emphasized the consequences of brain damage in the developing embryo, the importance of late radiation carcinogenesis, and the roles played by age and sex in human radiation responses. It also is prompting an increasing number of scientists involved in radiation protection to question the use of small animal models to quantify late radiation effects in humans. Contributions to this volume deal with experimental and other aspects of those problems. Finally, increasing confirmation of the dose rate response for densely ionizing radiations has highlighted the hazard they pose to humans in the terrestrial and extraterrestrial environments. Therefore, the intention of agencies in the United States and elsewhere to generate better funded and more scientifically perspicacious programs of space radiation biology is welcome. Possible interests of the military in that regard are also considered.
