In the past thirty years, the long-lived 137Cs was accumulated and eventually trapped in the mud of the discharge pond right in front of the waste storage and the reactor facility. The distribution of 137cs in mud was measured and contour-mapped to reveal the migration of trace levels of 137Cs in a period of three decades.7enjournal article
