Book excerpt: A solution to the problem of how one may determine the dose received by a detector that has a vertical barrier interposed between it and a horizontal infinite radiation field has been attempted. Steel barriers of effective mass thickness 0 to 73 lb/ft]2 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 Co]60 source that was pumped through an array of plastic tubing that covered a 100-ft semicircular area. An extrapolation to the infinite field case 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.
