What is radon, and why should it be tested?

Radon is a colorless and odorless gas that originates from the natural breakdown of uranium in soil, rock, and water. It is important to test for radon in homes because exposure to high levels of radon over prolonged periods can lead to serious health issues, particularly lung cancer. The gas can seep into buildings through cracks in floors and walls, construction joints, and gaps around service pipes.

Testing for radon is especially critical in certain regions where geological conditions may lead to higher concentrations of the gas. Since it is tasteless and invisible, residents cannot detect radon without proper testing. Implementing radon mitigation measures is necessary when a test indicates elevated levels, significantly reducing potential health risks.
