| Abstract: | In this paper,we processed the data of 13 radon stations since Sept. 1992 in Yunnan.The period variations from 80 to 90 days are separated from the radon observation data. We found that there are regional difference. The radon observation stations around epicentral region appeared the medium-period anomaly to destroy period variation in more than several ten months. |
