Multifunctional Radiation Detector
Product Introduction
This product utilizes a ZnS-coated scintillation detection method and can be used in either a fixed or portable configuration to directly or indirectly detect surface contamination. It is primarily designed to measure the level of alpha-radioactive contamination on surfaces—such as workbenches, floors, walls, hands, clothing, and footwear—within radioactive work environments and laboratories. The device is widely used across various sectors, including environmental protection, public security, the military, customs, border crossings, public health, the nuclear industry, and nuclear power plants.
