The inert gas radon after smoking is the second leading cause of lung cancer. Alone in Germany, according to the Federal Office for Radiation Protection approximately 1 900 deaths per year to the radioactive substance. Radon comes naturally in soil and can under certain circumstances from the underground into a residential building penetrate and for increased radiation exposure. It is therefore advisable, through the simple construction of the gas concentration in the houses to a minimum.
When construction of a building grant-plate concrete foundations and seals against the soil moisture an effective protection. Be lines posts in masonry, which contact with the surrounding soil, the area must be sealed well. The same is true for pipes, wall cracks and joints. Frequent and intense air, the concentration of radon in dwellings reduced. A tight fitting cellar door also prevents the spread of the gas in the higher floors, if it is through the masonry penetrate.
