GEOMETRY AND BARRIER ATTENUATION GENERATED BY A VERTICAL SLAB EXPOSED TO A PLANE CO60 SOURCE,
Abstract
A solution to the problem of how one may determine the dose redeived by a detector that has a vertical barrier interposed between it and a horizontal infinite radiation field was attempted. Steel barriers of effective mass thickness 0 to 73 lb/sq ft were employed. The detector was collimated so that regardless of its distance from the barrier it always saw a constant circular area on the barrier. The infinite radiation field was simulated by a traveling Co60 source that was pumped through an array of plastic tubing that covered a 100-ft semicircular area. An extrapolation to the infinite field case was attempted. The final results are expressed as ratios of dose received by an unprotected detector 3 ft above the plane. The experimental points are compared to a family of theoretical curves. (Author)
