Explanation
One of the radioactive indoor pollutants is:
(c) Radon.
Radon is a radioactive gas that can be found in indoor environments, particularly in buildings with poor ventilation and airtight construction. It is formed naturally from the decay of uranium and thorium present in soil, rock, and water. Radon gas can seep into homes and accumulate in enclosed spaces, such as basements and lower floors.
Exposure to high levels of radon gas over an extended period is a significant health concern. Radon is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC) and is the leading cause of lung cancer among non-smokers. Inhaling radon gas and its decay products increases the risk of developing lung cancer.
To mitigate radon exposure, it is recommended to test for radon levels in indoor environments, particularly in areas with high radon potential. If elevated levels are found, remediation measures such as improved ventilation, sealing cracks and openings, or installing radon mitigation systems can be implemented to reduce radon concentrations and minimize health risks.
