Soil Radon Intercomparison Measurements and Some Important Issues

Abstract

Abstract:

In order to ensure the accuracy and reliability of the key parameters of soil radon measurement results of radon mapping methods, our laboratory has the first time as China's organization to participate Radon Intercomparison Measurements, held at three radon reference sites of Cetyně, Bohostice and Buk in the Czech Republic in 2010. For the level of significance α=1%, testing results (orientation tests based on the comparison with the group) show that our measurements of cA (radon activity concentration) are in good agreement with that of the group of organizations participating in the comparison measurement. The decisive test based on the comparison with the databases of radon reference sites reveals that our resultant means of radon data are in accord with those of all successful organizations (N=180) which measured at radon reference sites since the year 2000. The results indicate that our soil radon measurement techniques have reached the international first-class level. After the radon international comparison, we found some important problems in soil radon measurement in China, such as instrument calibration, soil gas sampling technology. We proposed that the method for soil radon investigation should be improved and its technical specification should be carried out.
