  Article:   DISSOLVED URANIUM IN THE STREAM WATERS AROUND CRUCEA URANIUM MINE (EASTERN CARPATHIANS, ROMANIA).

Authors:  LUCIAN PETRESCU, ESSAID BILAL.
 
       
         
  Abstract:  Natural actinides are omnipresent in our environment. Various anthropogenic activities involving the processing or use of materials rich in uranium may modify the natural abundance of uranium in water. The knowledge of uranium concentration in river waters and its distribution is essential for predicting natural actinide migration and for the strategies concerning the rehabilitation of contaminated sites. The greatest risk imposed to the environment in the uranium mining areas, is represented by contamination of river system with dissolved radioactive materials. In such cases, rivers have to be completely disregarded as a water source for humans and animals.

Keywords: impact of mine wastes, uranium ore, Eastern Carpathians, Romania.
