α β surface contamination meter

       YD-0116 alpha beta surface contamination instrument is mainly used for radiation protection, environmental pollution, hospitals, nuclear power plants, isotope production, reactor plant where the surface, clothing, workbench, floor and other surface alpha beta radioactive pollution measurement.

Using scintillator and photomultiplier tube technology, it has the characteristics of low measurement background, high detection efficiency and long service life, and can measure αβ at the same time. It is a professional surface contamination meter with high cost performance.
