Abstract : A series of concentric annular zones on a steel slab were irradiated serially by a fixed, point gamma-ray source. Exposure rate measurements were made behind the barrier along the normal from the source. Next a steel cylindrical partition was placed behind the barrier with its axis normal to the slab. This partition was in contact with the slab and concentric with the source detector axis. Exposure rate measurements along the axis were repeated. The two sets of measurements are presented and compared zone by zone to see what changes were brought about by the insertion of the partition. (Author)
