Having pointed at radiation-hazardous radon that is present in underground water in non-uranium rocks and emanates as natural radioactive nuclides through natural and mining-induced faults in underground excavations, the author describes studies and laboratory tests aimed at maintenance of mine radiation safety through proper recording of individual radiation exposure of mine personnel, forecasting of radon migration intensity depending on equivalent equilibrium volumetric activity of radon in mine water, and elaboration of method and rate of work area ventilation. The research used the methods of laboratory mathematical modeling of desired parameters and relationships. The obtained results and the in situ measurements taken in non-uranium mines show good correspondence, which implies applicability of the mathematical modeling for forecasting of radiation safety of personnel in underground non-uranium mines.
