Lindberg and published by . This book was released on 1954 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: A radio-ecological survey of the area adjacent to Nevada Proving Grounds has been in progress intermittently from September 1951 to July 1953. Samples have been taken periodically of native soils, plants, and animals before, during, and after various test series at distances up to 30 miles from respective Ground Zeros. Data suggest that microcurie levels of radioactive fall-out are potentially available for absorption and/or metabolism by grazing animals at distances at least 15 miles from Ground Zero during the 24 hr following a detonation. The persistence of absorbed radioactive materials in rodent populations, as compared to the radioactive content of their isolated tissues, suggests that absorption is primarily a result of physical diffusion of available ions rather than actual metabolic selection and retention of the mixed fission products ingested or inhaled. Absorbed radioactive materials, therefore, appear to be in equilibrium with certain components of residual environmental contamination during the 90 days following a detonation.

Book excerpt: Underground earth-covered shelters were exposed G to a 16.4-kt, 300-ft tower shot at ranges of 1230 ft (one), 1450 ft (one), 1860 ft (five), and 3506 ft (one). Two types of basement shelters were constructed in each of the test houses at 3500 and 7500 ft. Instrumentation was by gammaradiation badges, paraffin cubes, and nylon swatches. Attempts were made to measure permanent deflections of concrete roof slabs. Mannequins were placed in several shelters for purposes of demonstration and observation of blast-caused movement. A weighted mannequin in the underground shelter at 1230 it was broken in half; an unweighted one (child size) was thrown to the floor. All other mannequins remained in place, undamaged. Paraffin cubes and nylon swntches showed no evidence of thermal damage. Fallout conditions made it impossible to determine initial gamma-radiation quantities. There was no cracking or permanent deflection of the concrete roof slabs. Except for a wood-covered, trench type shelter, which partially failed because of faulty construction, the shelters showed no blast damage. Thermal energy entering the shelters probably would not have caused skin burns to human occupants. Adequacy of the shelters under full design loads could not be determined because pressures were lower than expected, but the shelter designs were structurally acceptable under test pressures received.

Available in PDF, EPUB and Kindle. Book excerpt: Data was obtained on various blast phenomena near and within two communal shelters. An instrumentation system was designed and constructed for measuring five basic physical quantities: overpressure, acceleration, internal displacement, strain, and air temperaturc. Good pressure records were obtained which show not only the maximum pressures at various locations within the shelters but also a clear picture of the pressure differences resulting from the two shelter designs and the mode by which the pressure waves were amplified or attenuated. Although many of the temperature measurements did not produce significant results, many valuable data on this effect were obtained. Also presented are records of strain, displacement, and acceleration for one test. These records serve to define the secondardy effects of the blast. (auth).

Available in PDF, EPUB and Kindle. Book excerpt: Relative biological hazards of blast were studied in two types of communal air-raid shelters during Shots 1 and 8 (Nevada Proving Grounds, 1953). Dogs, restrained within the shelters during detonation, were studied pathologically and clinically for blast injuries. Two anthropometric dummies were test objects for displacement studies utilizing high-speed photography. Physical data included pressure vs time and air-drag determinations. During Shot 1 animals sustained marked blast damages (hemorrhages in lungs and abdominal organs), three dogs were ataxic, and the dummies were rather violently displaced. In Shot 8, however, no significant injuries were found in the animals, and the dummies were minimally displaced. Analysis of the physical data indicated that blast injuries and violent displacements may occur at much lower static overpressures than previously assumed form conventional explosion data. Furthermore, biological damage appeared to be related to the rate of rise of the overpressure and air drag, as well as the maximum overpressure values. These phases of the problem should be defined by further investigation.
