OECD/NEA and CEC intercalibration and intercomparison programme for Radon

Technical Report:

Abstract

Intercomparison of measurements of radon daughter activity concentration, unattached fraction and aerosol size distribution of radon daughters, was carried out by three of the reference laboratories: Australian Radiation Laboratory (ARL), US Department of Energy, Environmental Measurements Laboratory (EML) and US Department of Industry, Bureau of Mines (USBM), over the period March 17 to 21 1986, using the radon test chamber at the Australian Radiation Laboratory in Melbourne. The methodology, protocols and results for these measurements are described in detail. Results showed no systematic differences between the three laboratories, within the limits set by the counting statistics. In intercomparing methods for unattached fraction measurement, two of the reference laboratories (ARL and EML) used the single screen method. Good agreement was obtained between the two laboratories. EML and USBM also used graded screen devices for sizing these so-called unattached radon daughters. At the time of these measurements, the graded screen analysis methods available were of a preliminary nature. The ultrafine aerosol size distributions derived by EML and USBM show reasonable agreement in the position and magnitude of the derived peaks. Results of the measurements of the radon daughter aerosol size distributions between ARL, EML and USBM showed good agreement within the regions  More>>
