Barrier Attenuation of Air-Scattered Gamma Radiation

Abstract

An experimental study 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. A sealed radioactive source was pumped at a uniform speed through a long length of flexible tubing to simulate a ring source. Point-source measurements were made by stopping the source at a given location. Dose measurements were made with ionization chamber detectors.
