Fallout radiation protection provided by transportation vehicles

Description: Fallout radiation protection factors (PF's) were estimated for a variety of civilian transportation vehicles using measurements of the natural terrain radiation as a source. The PF values are below 2 in light vehicles, truck beds, or trailers; from 2.5 to 3 in the cabs of heavy trucks and in a railway guard car; and from 3.0 to 3.5 in the engineer's seat of heavy locomotives. This information can be useful in planning the possible movement of personnel from or through areas contaminated either by a wartime incident or a peacetime accident. The information may also be useful for studying the reduction of exposure to the natural terrestrial radiation environment provided by vehicles.

COMPARISON OF MEASUREMENTS IN ABOVE-GROUND AND BELOW-GROUND STRUCTURES FROM SIMULATED AND ACTUAL FALLOUT RADIATION

Description: An experimental study designed to provide a basis for estimating protection against fallout radiation was made on two types of structures at the Nevada Test Site. The two buildings studied were a lightly constructed building with a basement, and an underground group shelter. An idealized fallout radiation field was simulated by the use of a sealed radioactive Co/sup 60/ source that was pumped at a uniform speed through a long length of flexible tubing evenly distributed over the area of interest. Radiation levels at selected points inside the structures were measured with sensitive ionization- chamber detectors. These measurements were compared with measurements taken under actual fallout conditions at an earlier time and were also compared with the theoretical calculations. Protection factors from fallout data and mobile radiological measurements (MRMU) at the basement structure compared roughly within a factor of 2. This was good, considering the limitations of the two sets of data and other factors affecting the differences. Comparisons between protection factors from fallout data and MRMU data at the underground group shelter were excellent. MRMU data and theoretical calculations also compared satisfactorily. (auth)

EXPERIMENTAL EVALUATION OF THE FALLOUT RADIATION PROTECTION PROVIDED BY SELECTED STRUCTURES IN THE LOS ANGELES AREA

Description: A study designed to provide a basis for estimating protection against fallout radiation was conducted on four diversified structures in the Los Angeles, Calif., area. A fallout radiation field was simulated by a single radioactive Co/sup 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 a laboratory building, up to 10,000 in a family fallout shelter, from 50 to 150 in a police building, and from less than 10 to approximately 20 in a high school classroom.

Experimental Evaluation of the Fallout-Radiation Protection Provided by Selected Structures in the Los Angeles Area

Description: Report regarding experiments made to determine the fallout-radiation protection offered by four types of buildings in Los Angeles, California. The first structure was the Laboratory of Nuclear Medicine and Radiation Biology and the University of California at Los Angeles, the second was a fallout shelter, the third was the communications area of the Los Angeles Police Department building, and the fourth was a classroom.

Barrier Attenuation of Air-Scattered Gamma Radiation

Description: Report of a study that "was conducted to determine the attenuation provided by vertical and horizontal barriers exposed only to skyshine radiation from cobalt-60 and cesium-137 sources. Materials of steel, aluminum, concrete, and wood were used as barriers" (p. 5).
