Available in PDF, EPUB and Kindle. Book excerpt: The fallout hazard and protection factors in current use for large groups of buildings, i.e., urban residential areas, business districts, industrial complexes, government centers, Atomic Energy Commission facilities, and academic and medical institutions, are largely unsubstantiated by experimental evidence. These data are important for personnel protection on a national basis in the event of war and on a local basis in the event of certain types of nuclear accidents. The need for such information is discussed and methods for obtaining it are suggested. The methods suggested should provide a cross check of the data obtained on isolated structures under actual fallout conditions with the data from studies that made use of methods such as distributed point sources and a moving single-point source (as used in the Mobile Radiological Measurement Unit, Civil Effects Test Operations) to simulate actual fallout fields and with data from other studies in which predicted values of fallout protection were calculated from strictiy theoretical considerations.

Download or read book Behind the Fog written by Lisa Martino-Taylor and published by Routledge. This book was released on 2017-07-28 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behind the Fog is the first in-depth, comprehensive examination of the United States’ Cold War radiological weapons program. The book examines controversial military-sponsored studies and field trials using radioactive "simulants" that exposed American civilians to radiation and other hazardous substances without their knowledge or consent during the Cold War. Although Western biological and chemical weapons programs have been analyzed by a number of scholars, Behind the Fog is a strong departure from the rest in that the United States radiological weapons program has been generally unknown to the public. Martino-Taylor documents the coordinated efforts of a small group of military scientists who advanced a four-pronged secret program of human-subject radiation studies that targeted unsuspecting Americans for Cold War military purposes. Officials enabled such projects to advance through the layering of secrecy, by embedding classified studies in other studies, and through outright deception. Agency and academic partnerships advanced, supported, and concealed the studies from the public at large who ultimately served as unwitting test subjects. Martino-Taylor’s comprehensive research illuminates a dark chapter of government secrecy, the military-industrial-academic complex, and large-scale organizational deviance in American history. In its critical approach, Behind the Fog effectively examines the mechanisms that allow large-scale elite deviance to take place in modern society.

Book Synopsis Extended- and Point-source Radiometric Program by : Francis John Davis
Download or read book Extended- and Point-source Radiometric Program written by Francis John Davis and published by . This book was released on 1962 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: An extended-source calibration area was set up in the Nevada Test Site area to encourage a standardization of airborne radiometric instrumentation among several government agencies. and private companies. A simulated plane-source array was laid out with positions at 100-ft intervals in the form of a square 2000 ft on a side. For ground measurements a smaller square array of 100 positions at 10-ft intervals was placed in the center of the large array. Two sets of sources were used in the array. Cobalt-60 and cesium-137 sources of 4.5 and 15 mc, respectively, were available for the large array and sources one hundredth of these values in the smaller array. Point sources of Co(exp 60), Cs(exp 137), and I(exp 131) of the order of 2 curies each were available for comparison with the area sources. Measurements 3 ft above the area sources indicated 200 micronr/hr for Co(exp 60) and 225 micronr/hr for Cs(exp 137). Four government agencies and one private company participated in an intercalibration exercise during November 1960. Various types and sizes of aircraft from a Cessna 172 to a Douglas Dc-3 were used. Various instrumentation devices, mostly scintillation type detectors, were tested. Flights ranging from 100- to 1000-ft altitude included background measurements, instrument calibration, intercalibration, proof-testing equipment, comparison of point- and area-source measurements, measurements of air attenuation and buildup of gamma radiation, and gamma-ray spectral measurements.

Download or read book Biological Tolerance to Air Blast and Related Biomedical Criteria written by Clayton S. White and published by . This book was released on 1965 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experience with animals exposed in a variety of above and below ground structures during full-scale field operations at the Nevada Test Site in 1953, 1955 and 1957 were reviewed. The data were assembled and summarized to illustrate the nature of the blast-induced problems of significance in protective shelters, "open" as well as "closed". Potential hazards were related to the following: various patterns of variation in environmental pressure; translational events associated with transient, high-velocity winds, ground shock and gravity involving the impact of energized inanimate objects on the one hand the the consequences of whole-body displacement on the other; non-line-of-site thermal phenomena including hot objects and rapidly moving hot, dust- laden air and debris; and dust, in the respirable size range, sufficiently high in concentration even in "closed" shelters as to warrant design measures to minimize or eliminate the occurrence of small particulates whether arising from wall spalling or otherwise. Tentative biological criteria, conceived to help assess human hazards from blast-related phenomena, were presented. Relevant data from the literature and on- going research in environmental medicine were set forth to aid the reader in appreciating how the criteria were formulated, what information was extrapolated from animal data, and wherein "best estimates" were employed. "State-of-the-art" concepts were noted to emphasize areas in which more thinking and research must continue if more refined, complete and adequate criteria are to be forthcoming for assessing man's response to blast-induced variation in his immediate environment.

Book Synopsis Feasibility Study by : T. G. Provenzano
Download or read book Feasibility Study written by T. G. Provenzano and published by . This book was released on 1965 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and fabrication of a high-intensity, 14-Mev neutron source which can be operated on a hoist platform on the 1500-ft BREN tower at the Nevada Test Site (NTS) has been determined to be feasible. Utilizing the T(d, n)-4He reaction, the source should be capable of producing, as a minimum, an average intensity of 10-13 neutrons/sec for periods up to 4 hr. The type and placement of power supplies, ion sources, targets, and vacuum equipment have been examined and a preliminary conceptual design completed. Control systems, testing procedures, and construction operations were studied and are presented. It is estimated that the neutron source will cost from 260,000 to 300,000, occupy approximately 400 ft-3, weigh approximately 7.5 tons and require about 10 months to complete.
Book Synopsis Technical Concept by : F. F. Haywood
Download or read book Technical Concept written by F. F. Haywood and published by . This book was released on 1965 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A small but intense source of 14 Mev neutrons is to be mounted in the hoisting mechanism of the 1500-ft BREN tower at the Nevada Test Site. The experimental program, designated Operation HENRE, will be conducted during the spring and summer of 1965 and will be sufficiently comprehensive to characterize the radiation fields. In addition, a series of applied shielding experiments will include configurations of interest to both military and civilian laboratories. It is important that data be accumulated which will assist in understanding the apparent uncertainties in existing transport calculations, especially data which will give approximate values for effective neutron cross sections for air-over-ground transport. The neutron source will be operated at heights from about 25 ft to 1500 ft above the air-ground interface. The average neutron yield during operational periods of about 4 hours is expected to be equal to or greater than 10 13 n/sec.

Available in PDF, EPUB and Kindle. Book excerpt: Additional measurements at this same location were made to determine: (1) the skyshine dose rate as a function of distance from a cobalt-60 source placed on an air-ground interface: (2) the geometry factor describing a detector response to scattered gamma rays at the air-ground interface from a point isotropic cobalt-60 source on the ground 100 ft away; and (3) lip scatter and wall backscatter corrections for a detector in an open hole exposed to skyshine radiation from cobalt-60. The results apply to a variation of shielding problems. One practical application is the shielding provided by basement roofs and exposed basement walls from skyshine radiation originating from fallout.
