Description
Overview
GAOTek electromagnetic radiation detector portable radiation survey meter uses a ZnS coated scintillation detector that can be fixed or moved and detects surface contamination directly or indirectly. Mainly used for the detection of radioactive workplace and laboratory worktable, floor, wall, hands, clothes, shoes and other surface by alpha or beta radioactive pollution, widely used in environmental protection, public security, military, customs, ports, health, nuclear industry, nuclear power plant system. This instrument is a liquid crystal display small portable instrument, using the pulse shape discrimination circuit with intelligent analysis algorithm, can automatically distinguish alpha and beta particles, realize the simultaneous measurement of alpha and beta, which influence each other, to the lowest inhibition.
