Device Speeds Industrial Gamma Radiography.—The combination of a new carrier for sources of radiation and an automatic time clock mechanism allows the simultaneous examination of a number of objects without risk to the operator. Designed to give protection from radium sources up to 500 mgm. or radioactive isotopes of equivalent penetrating power, the carrier and the clock both work unattended, so ensuring that an operator is at no time subject to harmful radiation. There is a gate for single exposures when these are needed. The carrier is the bright container in the centre of the circle; the clock gear is attached. Castings to be inspected are ranged around inside the ring of plates.
