Effects of Building Eccentricity upon the Basement Ceiling Attenuation Factor, (B sub c)(X sub c, omega),
Abstract
As a result of the extensive measurements of in-and- down scattered radiation in the basement of a 20ft x 10ft building, an empirical basement ceiling attenuation factor, (B sub c)((X sub c), omega), was developed by Eisenhauer. Because of differences noted between this Laboratory's experimental data and that of other investigators who used scale model cylinders, it was thought that there may be some shape dependency in the basement ceiling attenuation factor. To test this theory, basement ceiling attenuation factor measurements were made in buildings with 4:1 and 1:1 eccentricity ratios and aboveground wall heights of 2 ft, 4 ft and 8 ft. The results of these measurements were compared to existing 2:1 length-to-width measurements and with Eisenhauer's empirical formulation. (Modified author abstract)
