Experimental Investigation on Diffusion of Radionuclide Radon Ejection from Uranic Well Ventilation in Atmosphere

摘要

Based on PIV technique and the digital image processing technique (DIPT), the water tank experiments are carried out to investigate radionuclide radon diffusion mechanism and airflow pattern on uranic well 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. The experiment result is compared with the survey on the spot, which proves that it is much reliable and believable for water tank experiment system to investigate contamination diffusion.
