Assessment of radon levels in soil and water
1Department of Physics and Materials Science, City University of Hong Kong, Kowloon, Hong Kong.
Abstract:
Radon gas and its progeny are radioactive and may induce lung cancer. A main source of indoor radon concentration is the radon gas which comes from the soil under a house or building. Therefore, accurate measurement of the radon concentrations in the soil are very helpful in identifying doubtful areas and in minimizing some radon hazards. A method of assessing the radon concentration in soil is described. The results were compared with the radon concentrations in associated water samples. It was found that the concentrations in soil and water were correlated, except for some anomalies and that the measurement of concentrations in soil were more direct and sensitive.
