Mitigation technique

Radon is one of the common contaminants inside buildings, with maximum presence in high potential areas classified as radon prone areas. This radioactive gas, which comes from the spontaneous disintegration of radium present in the earth's crust, can penetrate buildings and accumulate inside them. The spaces closest to the ground (basement and first floors) are the most affected. Its inhalation in high doses is associated with an increased risk of lung cancer. Several techniques are commonly used to mitigate its presence.

In approach to alleviating the problems causing ‘sick building syndrome’, many types of indoor air pollution removal products have been developed. In the various performance evaluation methods for these removal products, the pollutant constant-emission te
