THE 1ST NATIONAL INTERCOMPARISON OF RADON INTEGRATING DETECTORS IN RADON CHAMBER

A nation-wide intercomparison of radon integrating detectors (activate d charcoal, track etch and thermoluminescence, et al.) which 12 partic ipants were involved was conducted at Research Institute of Uranium Mi ning ( RIUM ) in China in 1989. The participants intercompared their d etectors under 6 exposure conditions ( low and high radon concentratio n, humidity and temperature ) provided by RIUM radon chamber . Most of detectors showed a quite good reproducibility. Exposure conditions se em to have influence on some detectors. which application conditions c ould not be considered thoroughly. Calibration of some detectors appea red to pose problems.
