Summary
In order to aid in the optimization of gamma-ray shielding, a method has been developed in which increments of lead shielding can be easily added to simulate a gamma shield. This is effected by enclosing an anthracene scintillation counter in a thick lead shield which has an aperture in one side that can be covered with 0- io 0.7-in.-thick lead discs. This instrument (the Revalet) has been experimentally operated in a known geometry with a source of known energy (Co/sup 60/) A comparison of the measured lead attenuation with Monte Carlo calculations indicated excellent agreement for 0 and 30 deg angles of incidence and good agreement at 60 deg . The cone angle of detection was 120 deg . (auth)
