Industry: any industry

Decontaminates radioactive materials and equipment, using chemical solutions, and sandblasting machine: Reads contamination level, using radiation meter, and sorts contaminated items by size and radiation level, following specifications. Weighs out and mixes chemical solutions in tank according to prescribed formula, and heats solution, using steam hose. Immerses objects, such as pipes, motors, valves, hose, and containers, in solution for specified time, using hoist. Places smaller objects in sandblasting machine, using manipulators or protective gloves, and starts machine to remove greater proportion of contamination and reduce immersion time. Places hot (radioactive) waste, such as sweepings and broken sample bottles, into disposal containers to be processed for land or sea burial. Cleans objects having radiation count under specified amount, using cloth, soap, solvents, wire brush, and buffing wheel. Records type of material and equipment decontaminated and method used. May accompany coffins of waste to disposal area. May monitor radiation-exposed equipment, plant and hospital areas, and materials, using radiation-detector measuring instruments, such as portable gamma survey meter, Geiger counter, and alpha-beta-gamma survey meter. May determine method of decontamination according to size and nature of equipment, and degree of contamination.
