We are pleased to inform you that the scope of accreditation of our radon calibration laboratory has been extended by the DAkkS by a third calibration point. This allows us to offer calibrations at 30 kBq/m³ (30000 Bq/m³) in addition to the previous radon activity concentrations of 300 and 3000 Bq/m³. This calibration point takes into account instruments that are to be used at higher concentrations, such as for soil gas measurements, water analysis, mining and many more.
