This work reports a novel method for determining Rn-222 (radon) in air using a radon-Po-218 calibration curve constructed by an absorbable non-volatile liquid scintillator (NVLS). The ability of this method to detect low natural concentrations of radon was confirmed from linear extrapolation of the curve between 500 and 8000 Bq/m(3). The calibration curve was created from data obtained from measurements performed in a radon calibration chamber at the National Institute of Radiological Science (NIRS) by using the least-squares method. The line had high precision and stability, and the required detection time was less than that of Po-214. An absorptive NVLS was used to collect radon and was found to be highly advantageous for alpha-spectrometry liquid scintillation measurements. Variations of the Ostwald coefficient due to changes in temperature and humidity, which affect radon absorption, were investigated and discussed. (C) 2016 Elsevier Ltd. All rights reserved.
