The Effect of Indoor Radon on Human Health, Review

Radon-222 is a radioactive gas that generally occurs in the Uranium-238 decaying chain. The existence of it in the natural world is connected chiefly with trace levels of 238U and its parent, radium-226, within soil, rocks, and groundwater. Inhaling of the short-lived radon daughters is predicted to produce around half of the effective doses of the environment. As a result, radon is the most commonly studied subject concerning environmental radioactivity research. Elevated radon levels in the interior of buildings pose a significant health risk to humans. Radon products are well known as the cause of lung cancer along with various types of cancer. Radon has been utilized as a tracer in the research of atmospheric transport processes. Radon has also been used in several other fields, including meteorology, water science, and medicine. The article overviews indoor radon in the environment and illustrates the effect of radon and its progeny on human health.
