According to the World Health Organization, radon gas is the cause of up to 14% of lung cancer. Radon expands through the air and enters a building affecting the quality of life of its habitants. Where does radon gas come from? Where is radon found?
Radon is a radioactive gas that emanates from rocks and soils and tends to concentrate in enclosed spaces like underground mines or houses. The infiltration of soil gas is recognized as the most important source of residential radon. Other sources, which include building materials and water drawn from wells, are less important in most cases.
Is radon gas dangerous?
In many countries, radon is the second leading cause of lung cancer after smoking. It's much more likely that radon causes lung cancer in people who smoke or have smoked than those who don't. Nevertheless, being exposed to the gas can be dangerous whatever the circumstances.
This fact proves the danger of radon gas, which affects people's health even when the concentration is considered low/moderate.
Can you measure radon gas?
It is possible to measure the amount of radon in an indoor space. However, the high temporal variation of indoor radon causes short-term measurements to be unreliable.
Can its impact be reduced?
To achieve a reduction in the overall risk which radon poses, prevention strategies (in new homes) and radon mitigation (existing homes) are needed.
The professionals of the building sector are key agents in the prevention and mitigation of radon. Thus, they must be trained in order to ensure that they are sufficiently skilled in this work field.
