Radioactive contamination monitor

At nuclear power plants, in order to prevent radioactive materials from spreading contamination outside the radiation control area, the surface contamination of all material transferred outside the control area is monitored. This paper presents an overview and describes features of: (1) personnel surface contamination monitoring assemblies for measuring the surface contamination on workers, (2) articles surface contamination monitoring assemblies for measuring the surface contamination on articles of all sizes, (3) laundry monitors for measuring the surface contamination on worker clothes worn inside the control area, (4) whole-body counters for measuring the worker's internal exposure, and (5) hand-foot-clothing contamination monitors for measuring the surface contamination on hands, feet and clothing.
