Natural dissolved 222Rn concentration increases with distance as Lot River water infiltrates into an alluvial aquifer. At distances greater than 150 m from the river, z22Rn has a constant value of ca. 55 Bq L-l. This is in agreement with the theory that the increase of 222Rn along the infiltration path can be described by a radioactive law. In the aquifer investigated, the infiltrating river water mixes withgroundwater from the neighboring hills. Radon is used to trace the infiltration of river… CONTINUE READING
