What is Radon?
Radon is a radioactive gas, invisible, odorless and tasteless.
Radon is the dominant factor in human exposure to natural radioactive sources that exist in nature. Radiation of population in buildings is significantly greater than outdoor exposure because it penetrates freely through defects in the outer shell and small cracks at the base.
Main sources of radon: soil containing radium, water and building materials. The radon travels through the land gas over long distances and reaches the surface terrain layers and so invades the buildings.
Inhalation of air containing high levels of radon over a long period may increase the risk of developing lung cancer. The World Health Organization determines the radon for the second most important factor causing lung cancer after smoking and the number one factor for people who have never smoked.
The only way to understand what is the radon concantration in the building and whether you are at risk the is the measuring it with detectors.
How often should the radon building be tested? It is necessary to test the building before and after major structural repair work, for example after installing a new heating system or switching on central heating.
Radon concentrations may vary across borders, and if an elevated content is measured in a building, this does not mean that there is a potential for radon penetration in the adjacent neighborhood. The penetration of radon most often occurs in the underground floors and in the first overground floor of the buildings, where there are also the expected places for applying the technical measures.
Reducing high levels of radon: There are methods that reduce radon concentration in buildings to 90% or more:
1.Do not allow radon to enter the building.
2.Decreasing the pressure under the building.
3.Ventilation of underground spaces and rooms.
4.Sealing of floors and walls.
5.Additional measures: restriction of smoking in the premises; increasing the flow of fresh air.
