    A Nordic meeting sponsored by the Nordic Liaison Committee for Atomic Energy, was held at Risø 2-4 June 1980 with the aim of in ter comparing detector systems for background radiation monitoring.

    Several Nordic Laboratories participated in the intercalibration programme with different types of instruments and detectors. Ionization chambers appeared to yield the most reliable results but in general large variations of detector responses Were found when the instruments were exposed identically. This demonstrates the need for intercomparison programmes and for establishing
    standardized calibration procedures.

    The present paper gives a description of the programme and presents the results for the assessment of background radiation monitoring with different sensitive doserate meters and integrating Tl dosimeters.
