Lagrangian Stochastic Model for the Dispersion of Solid-State Radionuclides Released from Uranium Mine Ventilation Shafts

Abstract:

Radionuclides released from uranium mine ventilation shafts would pose radiation exposure to the public and environment. A three-dimensional lagrangian stochastic model has been presented to study the atmospheric dispersion of solid-state radionuclides released from the uranium-bearing mine ventilation shafts. Meteorological conditions and geographical conditions including four downwind velocities (0.5, 1.0, 2.0, 4.0 m/s) and two underlying surface roughness characteristics (0.1 m, 1.0 m) were chose in the study. The radionuclides concentration distributions at various wind speeds and surface roughness were attained to evaluate the pollution in the vicinity of uranium mine ventilation shaft.
