Radon is a naturally occurring radioactive gas, which comes from the radioactive decay of uranium, the source of radon and is an extremely abundant element found in over 2700 rock types in Australia alone. It is present in small amounts in rocks, water and soil. It can easily escape from the ground and into the air where it can be inhaled.
Although radon has no smell, is colourless and tasteless, exposure to radioactive gases like radon and boron and radon daughter products can cause serious long-term health issues for workers.
Humans can be at risk of inhaling radon in some homes, caves or poorly ventilated underground mines, in particular uranium or coal mines.
