Environmental Monitoring

Our environmental monitoring system features a wide RPL glass surface to cover an extensive dose range of gamma rays, X-rays, and synchrotron radiation.


  • To monitor Gamma-ray around nuclear power plants
  • To measure X-ray in the hospitals
  • Air-absorbed dose monitoring on the border of controlled areas
