Background: Rapid measurement of radon exhalation rate is influenced strongly by external environmental factors. Purpose: This study aims to scientifically evaluate the accuracy of the measured result of radon exhalation rate according to the concept of uncertainty. Methods: A theoretical analytical model was estimated to study the measurement method of radon exhalation rate. The origin of the uncertainty was analyzed and employed to evaluate the accuracy of the result. Results: The result of the relative synthesis standard uncertainty diverges...
