Dust Monitor is one of the equipments that measure the concentration of air-borne radioactive materials. This monitor generally collects the dusts in the air by the air pumps, but this system has several problems. Therefore we made the prototypes of Dust Monitor and Dust Sampler that adopted static electrical collecting system, and examined these prototypes. As the result of examination, we confirmed that the static electrical collecting system has the same collection efficiency with air suction system and it is possible to use these prototypes in controlled area.
