DEVELOPMENT OF FILMLESS TECHNIQUE FOR RECORDING DEFECTS IN SHIP WELDS

Abstract

An investigation was made of the feasibility of a direct-reading (or filmless) technique in radiography using a 300 mc cobalt-60 source and a Geiger counter scintillator, and CdS or SeS crystals as detectors on a 1-in. thick steel welded test plate. A sketch and radiography of the welded test plate are shown. At present, the scintillator is the most useful detector of gamma radiation.
