Abstract: Radon is an international problem. With few exceptions, most countries have regions where homes have elevated levels of radon gas in indoor air. Radon is a naturally occurring colourless, odourless, tasteless and invisible gas, released as a by-product of the radioactive decay of radium, a highly radioactive metal found in most soils and rocks. Some of the gas seeps from the ground and diffuses into the air while some enters the ground water. No radon level is safe. The health risk is greatest, however, when the radon is abundant in the air. Its concentration depends largely on regional geological conditions. Tests in the US showed that nearly one in 15 homes has elevated radon levels. The World Health Organization and the health departments of most countries have declared radon a known human cancer-causing substance (carcinogen).
