How to reduce radon concentration in room? This might be a quite useful information. Ventilation of unoccupied spaces between the soil and the occupied space (e.g. vented crawlspaces) can reduce indoor radon concentrations by separating the indoors from the soil and reducing the concentration of radon below the occupied space. The effectiveness of this strategy depends upon a number of factors. These include the air-tightness of the floor system above the vented unoccupied space, and, with passive ventilation, the distribution of vents around the perimeter of unoccupied space.

VOC is the abbreviation of Volatile Organic Compound, which is emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. Studies have found that levels of several organics average 2 to 5 times higher indoors than outdoors. During and for several hours immediately after certain activities, such as paint stripping, levels may be 1,000 times background outdoor levels.
