222Rn is a colorless, and smell-less, inert gas with radioactivity. Although in rare amounts, this gas can be commonly found in the soil and water as a decay product of 226Ra. It is generally agreed that the crust break-up is one of the major factors that can cause 222Rn spike anomalies. Therefore, the 222Rn monitoring survey can be applied to correlate displacement of faults and, even earthquake activities. In this study, we set up 222Rn monitoring stations in Yanchau and Jungpu regions, respectively, for the purpose of measuring the soil radon level and, if possible, seeking for the relationship between the variations of 222Rn concentration and earthquake activities. |
