rádon

Rádon is a chemical element with the symbol Rn and atomic number 86. It is a noble gas and is the only naturally occurring element that is radioactive. Rádon is colorless, odorless, and tasteless. It is formed from the radioactive decay of uranium, thorium, and actinium. These elements are found in small amounts in soil, rock, and water.

Rádon is a significant health concern because it can accumulate in buildings. When rádon decays, it produces radioactive particles that can be inhaled. These particles can damage lung tissue and increase the risk of lung cancer. The risk is higher for smokers, but rádon can also cause lung cancer in non-smokers. The concentration of rádon in a building depends on the amount of rádon-producing materials in the ground beneath it, as well as how well the building is sealed.

Testing for rádon is recommended for all homes, especially those in areas known to have higher rádon levels. If high levels of rádon are detected, mitigation techniques can be employed to reduce the concentration. These methods often involve ventilation systems that draw rádon from beneath the building and vent it outdoors. Understanding rádon and its potential health effects is crucial for indoor air quality and public health.
