Abstract

Three different types of diffusion batteries for the measurement of radon progeny particle size distribution were intercompared as part of the International Intercalibration and Intercomparison Programme for Radon, Thoron and Daughters Measuring Equipment (IIIP). The IIIP is a joint project of the Nuclear Energy Agency of the Organisation for Economic Cooperation and Development and the Radiation Protection Research Programme of the Commission of European Communities. The intercomparisons were carried out at both the Australian Radiation Laboratory and the Environmental Measurements Laboratory. Eleven intercomparison tests were completed, covering both low and high concentrations of test aerosol. The test measurements of the three batteries were found to agree through the main part of the size spectrum, 50 to 500 nm. Disagreement was found if the test aerosol had substantial activity on particles larger than 500 nm; this was not surprising in view of the known limitations of diffusion batteries. There was some disagreement also for particles smaller than 20 nm, but we consider measurements in this area to be at the forefront of aerosol research.
