Measurements of Beta and Gamma Ray Characteristics of Shot Debris and Fall-Out of Nuclear Weapons written by H. D. LeVine and published by . This book was released on 1955 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of fall-out debris and radiation intensities over wide areas may be rapidly surveyed from the air. The development of instruments and techniques must be based on consideration of the beta and gamma characteristics of the radioisotopic constituents of the fall-out material. Radiation measurements in an aircraft may be related to surface conditions by an altitude correction factor, which has been determined by field measurements. Development and field testing, during the Teapot series, has resulted in a group of instruments useful for study of the radiation characteristics of fall-out debris. An aerial survey detector with automatic altitude compensator and a telemetering unit was also completed and tested.

Book excerpt: Unattended, automatic, continuously recording gamma-ray monitors were placed in 28 towns in populated areas adjacent to the Nevada Test Site throughout Operation Teapot. Readings no higher than 10 mr/hr were detected at these locations. No large quantities of fall-out were encountered. However, the continuous recording of the gamma radiation was compiled at each station. The equipment was reliable and operated unattended over relatively long periods. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Project 39.3 was to measure the thermal flux per unit area at a series of specified distances from a nuclear detonation. The instrumentation chosen was an Eppley thermopile indicating on a strip-chart paper recorder. Two stations failed to yield results because of power failures and blast damage. Results were obtained at 5500, 6800, 10,500 ft. These results follow the inverse-square-law fall-off, within the limits of reasonable experimental error.

Download or read book Operation TEAPOT Nevada Test Site, February - May 1955. Project 38.3. Evaluation of Civil Defense Radiological Defense Instruments. Report to the Test Director written by John H. Tolan and published by . This book was released on 1957 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were performed during Operation Teapot: (1) to investigate the beta-gamma exposure-rate ratio from fall-out to establish design criteria for high-range survey instruments, (2) to evaluate commercial radiological defense instruments, and (3) to investigate the feasibility of the use of commercial and amateur roll film and dental X-ray film as indicators of prompt gamma radiation. The results of the beta-gamma exposure-rate ratio measurements indicate that, for an instrument having a beta window of the order of 50 mg/sq cm thickness, the quantity of hazardous radiation not indicated by the instrument will not exceed a factor of 2. An analysis of the absorption data of fission-product radiation indicates the presence of high-energy beta radiation, low-energy gamma radiation, and secondary X-radiation in large quantities immediately postshot. The soft component tends to diminish rapidly, and the high-energy gamma radiation of the longer-lived fission products becomes predominant after approximately 2 days. The evaluation of commercial radiological defense instruments indicated that: (1) satisfactory calibration facilities must be developed, (2) ionization-chamber survey meters must have sealed chambers to avoid change in sensitivity with altitude, (3) an operational check rather than a simple battery check must be provided for all survey meters, and (4) dosimeters intended for monitoring applications must not demonstrate leakage resulting from high initial exposure and must be relatively insensitive to beta contamination.

Taplin and published by . This book was released on 1957 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: An evaluation of the acute inhalation hazard from radioactive fall-out materials has been made by analysis of results from animal exposures during field operations and from controlled inhalation studies in the laboratory. The results from exposing several groups of rabbits to fall-out material (by inhalation only) at stations located along two arcs, 7 and 106 miles from a tower detonation, are almost entirely negative. Urine specimens obtained during the first day following detonation contained minute but measurable amounts of soluble radioactive material which had a relatively short half life (1 to 2 days). Lung specimens had no detectable radioactivity when measured 6 to 21 day later; however, samples of intestine from the same animals still had measurable levels of beta activity. From careful consideration of numerous pertinent physical and physiological factors and from analysis of field and laboratory investigations, it is evident that there is no apparent situation in nuclear warfare where, during the first few days after the detoantion, one could inhale sufficient radioactive material to induce a serious radiation injury to lungs or intestines without simultaneously being subjected to supralethal doses of external beta-gamma radiation.

Download or read book Operation Teapot, Nevada Test Site, February-May 1955 written by R. F. Johnson and published by . This book was released on 1958 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is concerned with the activities induced in the surface of the earth near ground zero by neutrons released from a nuclear detonation. Gamma-ray spectral measurements of Nevada Test Site soil obtained from the vicinity of ground zero following Shots 1, 4, and 7 have been studied. From these it is concluded that the relative quantities of observed neutron-induced activity to fission-fallout activity are functions of height, yield, and type of detonation. Ten different soil samples were exposed to the neutrons from Shot 5. While only Na24 and Mn56 activities could be definitely found in sifnificant quantities in all soils, the relative amounts of these two radio-isotopes varied over a considerable range and, within reasonable accuracy, can be said to have been activated in proportion to the amount of sodium and manganese atoms present in the soil at the time of irradiation.

This book was released on 1956 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: To determine the durability of heavy-duty machine tools, 11 such tools of various types and sizes were exposed to the open shot of Operation Teapot. Two engine lathes and two knee type milling machines were installed on a concrete base simulating industrial installations at 2750 ft from Ground Zero. One 200-ton hydraulic press was installed immediately behind a two-story brick dwelling at 4700 ft from Ground Zero. Two vertical milling machines, two pressure vessels, and two drying ovens were placed in typical industrial buildings (Butler and Armco) at 6800 ft from Ground Zero. Positioning and anchoring of machines were varied to induce damage from breakage and flying debris. Also exposed to the blast were basic lubricating oils for machine tools. Damage was understandably the most severe at the 2750-ft station and was minor at the 4700- and 6800-ft stations. Only one machine was completely demolished, and it was discovered in a postshot inspection that the machine's subbase had been broken prior to the blast. Flying debris, not blast, created the major damage to the machines. Vulnerability of machines to damage appears to exist in the failure of fragile external parts; and even though none of the 11 pieces used in the test was large enough to be rated as a heavy-duty machine tool, the major castings and forgings were not damaged. The lubricants appeared to suffer no damage under the conditions of the test.

Williamson and published by . This book was released on 1955 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic-blast exposure tests on commercial communications equipment were conducted during Operation Teapot, Apple II shot. These tests were made to provide civil defense planners with data for qualitative predictions of the probable survival range, the extent of damage, and nature of repairs required to restore communication service after a blast. Approximately 150 widely diversified units of commuications equipment (mainly electronic, but including sirens) were exposed. Exposed items were in or near groups of structures located at approximately 4700 and 10,500 feet from ground zero. Where possible, identical products were exposed at these two locations, so that one set of items would be subjected to moderately severe damage and the other set to light damage. Tests showed that commercial communications equipment was generally more resistant to nuclear explosion damage than the structures in and near which the products were exposed.

Johnston and published by . This book was released on 1956 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: One equipment control building designed to be blast resistant and two each of three standardized types of metal warehouse or utility buildings were exposed to the effects of a nuclear device detonation. One of the utility buildings was frameless, with deeply corrugated wall and roof sections; a second was very largely frameless, using interlocking channel sections; and the third the aluminum-panel wall and roof covering was supported by girts and purlins, which in turn were supported by steel frames. Because of atmospheric conditions at the time of an earlier detonation in the test series, one of each of the three types ot utility buildings was exposed to approximately 0.7 psi overpressure before the planned test. In the planned test, held during the open shot (Apple II), one of each of the three types was exposed to approximately 3.0 psi overpressure and one to 1.3 psi, with the intention of bracketing their overpressure survival range and obtaining data for possible economic redesign for improved blast resistance. The equipment control building used continuous-welded steel frames and reinforced-gypsum curtain-wall construction. The control building was exposed to apporximately 4.1 psi, in the anticipated fringe zone of major structural damage, to determine its protective capabilities. The blast-resistant equipment control building was not structurally damaged by the blast, thus exceeding the expectations of the design. Each of the three utility buildings received severe damage at the near range, one being completely destroyed, whereas at the far range the damage in every case was repairable.
