Influence analysis of standby sampling points on water Radon observation at Hanzhong seismic station

In this paper, two water Radon sampling points at Hanzhong seismic station are taken as experimental objects. Through comparative observation, the Radon value and water temperature on the same day at the main and standby sampling points are obtained, and the reasons for the difference are analyzed. It is shown that the observation results at the standby sampling points will have a direct impact on the water Radon observation at this station, and increase the uncertainty of data analysis and affect the continuity of observation results.
