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.

Book Synopsis Experimental Evaluation of the Radiation Protection Provided by an Earth-covered Shelter by : Zolin G. Burson
Download or read book Experimental Evaluation of the Radiation Protection Provided by an Earth-covered Shelter written by Zolin G. Burson and published by . 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.

This book was released on 1962 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study designed to provide a basis for estimating protection against fallout radiation was conducted on four diversified structures in the Los Angeles, Calif., area. This study was sponsored by the Civil Effects Test Operations (CETO), Division of Biology and Medicine, U.S. Atomic Energy Commission. The four buildings studied were (1) the Laboratory of Nuclear Medicine and Radiation Biology at the University of California at Los Angeles (UCLA); (2) a family fallout shelter; (3) the communications section of the Los Angeles Police Department building; and (4) a typical classroom located at North Hollywood High School. A fallout radiation field was simulated by the Mobile Radiological Measuring Unit. The unit employed a single radioactive Co(exp 60) source, which was pumped at a uniform speed through a long length of tubing evenly distributed over the area of interest. Measurements of the radiation levels at selected points inside the structures were made with highly sensitive ionization- chamber detectors. Protection factors ranged from 10 to 2000 in the UCLA building, up to 10,000 in the family fallout shelter, from 50 to 150 in the communications section of the police building, and from less than 10 to approximately 20 in the high school classroom.

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.

Book Synopsis Methods and Techniques of Fallout Studies Using a Particulate Simulant by : William Lee
Download or read book Methods and Techniques of Fallout Studies Using a Particulate Simulant written by William Lee and published by . This book was released on 1962 with total page 24 pages. 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. This report discusses the need for such information and suggests methods for obtaining it. 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 Qperations) to simulate actual fallout fields and with data from other studies in which predicted values of fallout protection were calculated from strictly theoretical considerations.
