“…In particular, a number of previous studies have evaluated radon exposure levels in subway stations and facilities in metropolitan cities in Korea. [31][32][33]43,44 Thus, aer excluding subway stations and facilities in this study, underground public-use facilities such as underground public areas, tunnels, parking lots, underground spaces in residential and commercial buildings, and offices were selected as study subjects. Due to ongoing repair and construction on sites, some facilities were also excluded from this study.…”

“…The gaseous nitrogen and sulfur oxides were abundant in the indoor subway environment. The airborne radon levels in the subway cabins were increased by 53% after PSD installation in the subway station [1]. Radon is a colorless, odorless and tasteless gas produced by radioactive decay of uranium and thorium and its progenies have health hazards for human.…”

A computational model of existing Seoul subway tunnelwas analyzed in this research. The computational model was comprised of one natural ventilationshaft, two mechanical ventilationshafts, one mechanical airsupply, a twin-track tunnel, and a train. Understanding the flow pattern of the train-induced airflow in the tunnel was necessary to improve ventilation performance. The research objective wasto improve the air quality in the tunnel by investigating train-induced airflow in the twin-track subway tunnel numerically. The numerical analysis characterized the aerodynamic behavior and performance of the ventilation system by solving three-dimensional turbulent Reynolds-averaged Navier-Stokes equations. ANSYS CFX software was used for the computations. The ventilation and aerodynamic characteristics in the tunnel were investigated by analyzing the mass flowrateat the exits of the ventilation mechanicalshafts. As the train passed the mechanical ventilation shafts, the amount of discharged-air in the ventilationshafts decreased rapidly. The air at the exits of the ventilation shafts was gradually recovered with time, after the train passed the ventilation shafts. The developed mechanical air-supply for discharging dusty air and supplying clean airwas investigated.The computational results showed that the developed mechanical air-supplycould improve the air quality in the tunnel.
