A. Radon is a radioactive gas that is formed naturally by the breakdown of uranium in soil, rock and water. As a gas, radon is slowly released from the ground, water, and some building materials that contain very small amounts of uranium, such as concrete, bricks, tiles and gyproc.
Of all the elements and isotopes in the decay chain, radon is the only gas. Because radon is a gas, it can easily move through small spaces between particles of soil and thus enter a building. Radon can enter a building as a component of the soil gas and reach levels many times higher than outdoor levels.
