2. Relevance of research Like other oil-producing territory of the Republic of Apsheron oil-producing contaminated natural radionuclides (uranium, thorium, radium, etc.) that are in formation water coming to the surface with oil. Produced water is pumped together with oil and is separated from it flows through channels in the artificial lake. As a result of deposition and accumulation of isotopes 235 U, 238 U, 226 Ra, 228 Ra и 224 Ra and 224Ra and their degradation products are detected in large quantities in water, sediment and soil in oil production.

4. This leads to increased levels of gamma radiation in the areas of accumulation, so cleaning the contaminated areas of the radioactive isotope is an urgent task. Analysis of the formation water and sediment showed that the bulk of them from the radionuclides uranium and radium. In nature, in contrast to the compounds of thorium, radium and uranium compounds are much more soluble in water. Particularly dangerous water soluble uranium, mainly because of its chemical toxicity and less radiotoxicity Therefore, the study of clean water basins soils from uranium and fission products of great interest.
