Radon is a radioactive element that occurs naturally as a byproduct of uranium decay in soil, rock, and water. It is colorless, odorless, and tasteless, which makes it difficult to detect without specialized equipment. This gas can accumulate in enclosed spaces like basements, potentially leading to health risks when inhaled over long periods. Prolonged exposure to radon can increase the likelihood of developing lung cancer, making awareness and testing crucial. Mitigation strategies, including proper ventilation and sealing of cracks in foundations, can help reduce radon levels in homes and buildings, ensuring a safer environment for occupants over time.
