The aim of paper was development of an adequate mathematical model for predicting the level of environmental pollution by radionuclides emitted as a result of oil wells drilling. This problem was solved using Gaussian Plume Model which allowed to determine the concentration of radionuclides at a given point in space. Impurity flux density in Bq/(m2 s) was been simulated.
