Radon is classified as what type of carcinogen?

Radon is classified as a Group A Carcinogen, which means that there is sufficient evidence to conclude that it is a known human carcinogen. The classification is based on extensive research, particularly studies that have shown a clear link between radon exposure and lung cancer. This connection is especially pronounced among miners and individuals who have been exposed to elevated radon levels in homes.

Group A carcinogens are those for which there is strong evidence of carcinogenicity in humans, derived from epidemiological studies. In the case of radon, both environmental and occupational studies have consistently demonstrated that prolonged exposure increases the risk of developing lung cancer, establishing it as a serious health risk. Therefore, understanding radon as a Group A Carcinogen emphasizes the importance of radon testing and mitigation in homes and buildings to protect public health.
