Abstract:

Experiments were carried out to measure the shielding effectiveness of concrete slabs, both ribbed and equivalent smeared configurations, for broad parallel beams of essentially monoenergetic radiation. The broad-beam source configuration was simulated by means of a movable source of cobalt-60 radiation collimated to a thin beam, and by use of a line detector. Angles of incidence of 0 degrees normal, 45 degrees, and 60 degrees were investigated. Results were compared with previous Monte Carlo calculations and shown to be consistent with them, provided certain factors, such as the angular spread of the collimated beam, were taken into account.
