The paper highlights topical issues of the drill cuttings radioecological safety assessment in the process of waste management. Particular attention is paid to the necessity for continuous radioecological research and well-timed receipt of their results. The conducted research allows to solve the scientific and practical problem of radioecological studies optimization during management of drilling waste by development of the new methodical approach to their processing and interpretation. The most widespread natural radionuclides Th232, Ra226, K40 were selected as the focus group. An example of experimental determining the drill cuttings radiological properties depending on the depth of drilling is given. The results of these works were analyzed using the methods of regression and correlation analysis. The regression dependence of the specific effective radioactivity on the sampling depth for the investigated well is obtained. An approach using the obtained dependences as calibration graphs for a preliminary radiological assessment of drill cuttings of a similar genesis is proposed. The logical-informational model that implements this approach is described. It is shown that the use of the logical-informational model optimizes the decision-making process on the suitability of drill cuttings for their utilization to a useful product – soil-like reclamation mixtures.
