Improvements for Measurement of ²²²Rn in Water

Abstract

A measurement of ²²²Rn in water, liquid scintillation counting of radon extracted with toluene, was improved: (1) Weight measurement was used instead of volume measurement, (2) solubility approximation equations were revised. These made the experimental operations easier and improved temperature dependence of the radon concentration in calculation, Several solubility data were evaluated by temperature dependence of the radon concentration.
