Laboratory Model for Diffusion of Radionuclide Radon Ejection from Uranic Ventilation in Atmosphere

摘要

Water tank experiments are carried out to investigate radionuclide radon diffusion mechanism and airflow pattern on uranic ventilation outlet over complex terrains. Various water flow velocities are used to represent the different wind speeds. The velocity vector graph and streamline graph are got to explain the diffusion of radionuclide radon with PIV technique in water tank.
