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 235U, 238U, 226Ra, 228Ra и 224Raand 224Ra and their degradation products are detected in large quantities in water, sediment and soil in oil production.

4. Relevance of research • 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.
