Industrial waste containing radioactive isotopes (from U-decay series) was released into Ebro river basin due to the activity of a dicalcium phosphate (DCP) plant for a period of more than two decades. Gross alpha, gross beta, (40)K, (226)Ra and (210)Pb activities were determined in several sludge samples taken at different depths from different points in the area of influence of the DCP plant located in Flix. Samples were collected from two different zones: one in front of the DCP plant and the second in front of a wastewater treatment plant installed several years after the DCP plant. The data obtained verify the influence of industrial DCP production on radioactivity levels present in the area.
由于二水磷酸氢钙 (DCP) 工厂的活动，含有放射性同位素（铀衰变系列）的工业废物被排放到埃布罗河流域，持续了二十多年。在位于菲利克斯的 DCP 工厂影响范围内的不同地点，从不同深度采集了几个污泥样品，测定了总阿尔法、总贝塔、（40）钾、（226）镭和（210）铅的活度。样品取自两个不同的区域：一个在 DCP 工厂前面，另一个在 DCP 工厂几年后安装的废水处理厂前面。所获得的数据证实了工业 DCP 生产对该地区放射性水平的影响。
