Radon is a natural radioactive gas, originating from uranium which occurs in many types of rock. All water and air contains some radon, though levels are normally much too low to be of concern. For many years it has been recommended that, if the concentration of radon in indoor air exceeds the Action Level of 200 becquerels per cubic metre, steps should be taken to reduce it.
It is now recognised that some private water supplies contain levels of radon which should also be controlled. However, it is important to recognise that radon in water almost certainly presents a smaller public health hazard than radon in air, both in term of the numbers of people exposed to high levels, and in terms of the risks to the most exposed individuals. People living all their lives at the Action Level run the risk of a few percent of developing lung cancer. On average, about one in thirty people exposed for a lifetime at the Action Level would be expected to develop lung cancer.
New research suggests that around 1000 people may die each year as a result of radon, with smokers at a greatly increased risk.Measuring Radon in the Home
