Distribution of Long-Lived Radionuclides of the 238U Series in the Sediments of a Small River in a Uranium Mineralized Region of Spain

Author(s): Lozano JCP, Blanco R, Vera TF

Abstract

A study is presented on the distribution and mobilization of the natural U isotopes (238U and 234U), 230Th, and 226Ra in the sediments of a small river crossing an uranium mineralized zone where a disused uranium mine is located. Due to the preferential directions for surface run-off waters and to the mine’s situation, one sampling point along the river bed was identified as a point of accumulation of radionuclides.
