International InterComparison of Radon 222 Activity Concentration Calibration Facilities

The Coalition of International Radon Associations (COIRA) organized an inter-comparison of Rn-222 (radon) activity concentrations reported by calibration laboratories. A set of three AlphaGUARDs were used as transfer reference instruments against which to compare reported Rn-222 activity concentrations. Rn-222 activity concentration calibration facilities (sometimes termed chambers) from seven countries (Australia, US, Czech, Spain, England, Sweden, […]

Design and Development of a Canadian Radon Calibration Chamber

The Radiation Safety Institute of Canada has operated a radon chamber for more than 30 years at its National Laboratories, in Saskatoon, Saskatchewan, Canada. The chamber has and continues to be used for quality control, performance testing, and research and development for the Institute’s personal alpha dosimeters under its federally licensed Personal Alpha Dosimetry Service […]
