Abstract
A scanning device for examining an object with gamma rays with shielding for protection from radiation and protection of the mechanism from heat by a cooling jacket formed by spaced plates around the object. The shielding is formed by a pair of shutter-halves forming a lead shutter with mechanism to move the shutter-halves toward and away from each other and one of the shutter-halves mounted on a rotating drum which also carries three gamma ray sources. Gamma ray detectors are mounted in a circle concentric and outside the circle of the sources.
