Spatial and temporal distribution of the radioisotopes concentrations were determined in sediments near the surface and core samples extracted from two reservoirs located in an arid region close to Chihuahua City, Mexico. At San Marcos reservoir one core was studied, while from Luis L. Leon reservoir one core from the entrance and another one...

The main interest of this study is to assess whether uranium deposits located in the San Marcos outcrops (NW of Chihuahua City,Mexico) could be considered as a source of U-isotopes in its surrounding environment. Uranium activity concentrations weredetermined in biota, ground, and surface water by either alpha or liquid scintillation...
