Radongáz

Radongáz is a naturally occurring radioactive gas that is colorless, odorless, and tasteless. It is produced from the radioactive decay of uranium, thorium, and radium, which are present in small amounts in rocks, soil, and water. Radongáz can seep into buildings from the ground through cracks in foundations, walls, and floors. It can also be released from building materials that contain radium.

Exposure to high levels of radongáz has been linked to an increased risk of lung cancer. The World Health Organization estimates that radongáz is the second leading cause of lung cancer after smoking. The risk is higher for smokers who are also exposed to radongáz.

Radongáz can be present in both indoor and outdoor air, but indoor concentrations are typically much higher because the gas can accumulate in enclosed spaces. Homes, schools, and workplaces can all have elevated levels. Testing for radongáz is the only way to determine if it is present and at what concentration. Short-term and long-term testing devices are available.

If high levels of radongáz are detected, mitigation strategies can be employed to reduce the concentration. These methods often involve improving ventilation to allow the gas to escape the building. Sealing cracks and openings in the foundation can also help prevent radon from entering. Professional radon mitigation services can assess the situation and implement the most effective solutions. Regular testing is recommended, especially after any structural changes to a building or in areas known for higher radon levels.
