Specific activity of drilled cuttings produced during oil production in the Rebublic of Tatarstan
According to the results of gamma-spectromet-ric analysis of drilled cuttings samples taken in the region of PJSC “Tatneft” activity, effective specific activity of natural radionuclides (potassium-40, thorium-232 and radium-226), which does not exceed the most stringent standard at 370 Bq/kg, regulated by norms of Radiation Safety Standard-99/2009 is calculated. Under the document, there are no restrictions on the use of such materials in the economic activity.
