Abstract
Modern people stay at indoor places about 90% of a day. Radon-222 is a gas produced radioactive decay of the element radium. And, radon is one of the major indoor air pollutants moves into the underground space through various routes and is considered to cause lung c hurting the lung tissues, In this study, we measured the subway radon level at 9 stations o According to test results, we can figure out the concentration of radon by lines, times, and m points. So, it was found that ventilation conditions are the most important factors in the su quality. Finally, we suggested effective and economic management methods of air pollution subway.
