Radon is a naturally occurring radioactive gas that can seep into houses through cracks and openings in the foundation. It is dangerous because it can accumulate to high levels in indoor air, increasing the risk of lung cancer when inhaled over a long period of time.
Radon can enter houses through any openings or cracks in the foundation, including gaps between the walls and floors, sump pumps, and utility penetrations. It can also enter through well water and building materials.
Exposure to high levels of radon can increase the risk of lung cancer, as it is the second leading cause of lung cancer after smoking. The risk is higher for smokers, but non-smokers can also develop lung cancer from radon exposure.
You can purchase a radon testing kit from a hardware store or contact a professional to conduct the test for you. The most common type of test is a short-term test that takes 2-7 days to complete. Long-term tests are also available, which take 90 days or more to get accurate results.
If high levels of radon are detected in a house, there are several measures that can be taken to reduce the levels. These include sealing cracks and openings in the foundation, installing a radon mitigation system, and improving ventilation in the house. It is important to consult a professional for the most effective solution for your specific situation.
