This book was released on 1960 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The protection afforded against simulated fallout radiation has been evaluated for several typical homes in the Oak Ridge area. Nine houses were chosen to represent a variety of construction materials, topographical conditions, and sizes; they included three types of Oak Ridge Cemesto houses, one concrete-block house with a basement "fallout shelter," and two woodframe houses. The protection factor (ratio of open-field exposure dose rate to exposure dose rate in the house) in all these houses ranged from 2 to 5 on the main floor and from 5 to 30 in the basements, except in the fallout shelter, where the protection factor was greater than 100. The analysis showed that sloping lots, common to Oak Ridge, do not appreciably affect the protection factor for the main floor. Owing to the generally increased exposure of the basement walls on such lots, the protection factors in the basements were typically lower than in similar basements built on level lots.

This book was released on 1962 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was undertaken to determine the protection against fallout radiation provided by an earth-covered shelter. The study indicated that the shelter offered excellent protection from fallout radiation deposited on and around the shelter. This study also added additional data to the research in radiation shielding provided by various structures which is being conducted by the Civil Effects Test Operations, Division of Biology and Medicine, U.S. Atomic Energy Commission. A fallout radiation field was simulated by pumping, at constant speed, a sealed Co60 source through a long length of tubing which was evenly distributed over an area. Radiation measurements were made Inside the shelter by dose-integrating ionization chambers. In general, the results indicated that the protection factor (ratio of the open-field exposure dose rate to the exposure dose rate in the structure) was approximately 5000 in the center of the shelter, increasing to 10,000 to 15,000 along the sides, and decreasing to about 3000 near the ends. Directly below vents the protection factor was found to be approximately 2500 at the 3-ft level. The shelter was a half-round corrugated-steel structure covered by a minimum of approximately 2 ft of earth on the top and 5 to 7 ft of earth on the sides.

Download or read book Experimental Evaluation of the Fallout-radiation Protection Afforded by a Southwestern Residence written by Z. Burson and published by . This book was released on 1962 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study was conducted to determine the fallout-radiation protection afforded by a residence representative of a type of construction much in favor in the Southwest: a single-story stucco and frame house with a heavy shake roof and no basement. This study was one of many such studies sponsored by Civil Effects Test Operations, Division of Biology and Medicine, U. S. Atomic Energy Commission, for the purpose of evaluating the protection presently afforded by ordinary homes and structures against the dangers of fallout radiation. The protection afforded by the home was determined by simulating a fallout-radiation field above and immediately surrounding the house and measuring the radiation level within. The radiation field was simulated by pumping a sealed Co(60) source through a long length of tubing evenly distributed over the test area. Highly sensitive dose-integrating ionization chambers were used to measure the radiation level inside the structure. The test was performed rapidly, easily, and safely. Valid statistical data were obtained even though the radiation level was of such low magnitude that it was unnecessary to evacuate any of the neighboring homes. The protection factors within the house (ratio of exposure dose rate in the open field to exposure dose rate in the structure) ranged from 2.8 to 4.4, depending on the location. The results compare favorably with those found in previous exercises under similar conditions.

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.

This book was released on 1961 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study was made to determine the protection against fallout radiation provided by the Medical Research Center at Brookhaven National Laboratory. Shelter areas in the basement which could be used as emergency hospital wards were found to offer satisfactory shielding during a fallout situation. This study also added data to the nuclear energy civil effects research being conducted by the Civil Effects Test Operations, Division of Biology and Medicine, United States Atomic Energy Commission, on the radiation shielding provided by structures. A fallout radiation field was simulated by pumping a sealed Co60 source through a long length of evenly distributed tubing. Radiation measurements were made inside the Medical Center by dose-integrating ionization chambers. In general, the protection factors (ratio of open-field exposure dose rate to structure exposure dose rate) varied from 200 to 400 throughout the basement and from 12 to 20 on the first floor. Two isolated areas in the basement Indicated much higher protection factors (1400 and 4000). Since this was a large one-story structure with a flat roof, fallout on the roof would probably contribute more than 90 per cent of the total exposure dose rate at most points within the building during a fallout situation. Methods of significantly increasing the protection at most points of interest are limited to increasing the shielding material between the shelter areas and the roof or removing the contamination from the roof.
