Sentinel Gamma Ray Projectors 680B Projector with OPL

The SENTINELTM Model 680B source projector combines the penetrating radiation of Cobalt-60 with the mobility provided by the use of depleted uranium shielding. It is designed for the radiography of steel from 1 in to 7 in (25 mm to 175 mm) thick and light alloys 3 in to 15 in (75 mm to 375 mm) thick. All components have been developed to provide safe, reliable service and long life under the harsh conditions of industrial use. The durable case is designed to ease rigging operations. A lock is incorporated to prevent use by unauthorized personnel. The source cannot be projected until the control cable is correctly connected. The projector can not be locked or the control cable disconnected until the source is safely stored. Projectors with codes that include the letter A or B are fitted with the unique Posilock device which automatically secures the source assembly in the stored position on retraction. Remote controls allow the operator to control the source at a distances of 35 ft (10.7 m) or 50 ft (15.2 m). When the source is in the exposure position the control can be a total distance of 46 ft (14 m) using 25 ft controls, 63 ft (19.2 m) using 35 ft controls, or 99 ft (30 m) using 50 ft controls.
