The surface contamination monitoring instrument for hands and feet is mainly used in radioactive control channels of nuclear power plants or related nuclear facilities to monitor surface contamination of the hands and feet of workers from the control area. By analyzing the data, potential accidents can be discovered in a timely manner, in order to detect pollution and prevent pollution transfer. It is one of the means to ensure safe production in nuclear power plants or related nuclear facilities and other radioactive isotope application departments, and can also be used in other radioactive isotope application departments.
