Abstract : The angular distribution of Co to the 60th power gamma radiation backscattered from water, concrete, iron, and lead targets was measured. A collimated beam of radiation was incident at angles of 0 deg, 30 deg, and 60 deg to the target normal. The targets were all of sufficient thickness to simulate an infinate thickness for backscattering. Comparison of the results with the semi-empirical formula of Chilton and Huddleston for differential dose albedo from concrete showed good agreement. (Author)
