Monnin Ciencias de la Tierra Radon aquifer rainfall response Time variations of radon-222 concentrations in the water of the Lamalou, France, karst aquifer have been measured. Themeasurements have been performed at the spring outlet of the aquifer as well as in boreholes drilled from the surface. Radonconcentrations variations recorded in the main outlet and in a well located next to it are compared. The response to rainfalldepends strongly on the season when rainfall occurs. During summer, a rain episode is followed by a radon response in the wellbut not at the spring. Furthermore, the decay of the radon signal obeys strictly the radioactive decay law. Accordingly, duringsummer the water of the aquifer barely moves horizontaly. On the contrary, during the rainy season, every rainfall induces a signalboth in the well and at the spring reflecting a different mechanism and a mixing process of the water in the main outlet. 2002 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56841310 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.41 |
