“…The primary external factor causing this phenomenon is seasonal variation in outdoor temperature [48]. Jin et al [49] summarized the characteristics of underground indoor radon, its progeny, and the source to those of unequilibrium radon and its progeny. Underground indoor radon levels are influenced not only by building materials, but also by geological structure, air tightness of houses, indoor ventilation rate, people's living habits, and other factors.…”

Because of rapid urbanization, traffic problems, and other factors, underground spaces have been used more in the twenty-first century. Large underground spaces are required for underground city, metro, tunnel, mine, industrial and agricultural engineering, and civil air defense engineering. Underground spaces with varying thermal, ventilation, and lighting environments can face problems of comfort, health, and safety. High temperatures, high humidity, difficulty in flue gas emission, harmful microorganisms, radon, and physical and psychological problems are examples of issues. Air quality control technologies for underground spaces, such as ventilation, dehumidification, natural energy utilization, smoke extraction, and ventilation resistance reduction, are discussed. Ventilation for smoke-proofing/evacuation is also extensively addressed.
