What is radon

Radon and buildings. What is radon gas?

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 inhabitants. 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 usually less frequent.

Is radon gas dangerous?

In many countries, radon is the second leading cause of lung cancer after smoking. It’s much more probable that radon causes lung cancer in people who smoke or have smoked, but being exposed to this gas might pose a risk either way.

Besides, this gas can have an impact on people’s health even if its concentration is considered low or moderate.

Can radon gas be measured?

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.

How can its impact be reduced?

To mitigate the overall risk that radon poses for our health, prevention strategies (in new homes) and radon reduction strategies (in existing homes) are needed.

The professionals of the building sector are key agents in the prevention and mitigation of radon.
