Radon is a naturally occurring radioactive gas formed in the ground by the radioactive decay of uranium,

Which is present in varying quantities in all rocks and soils. Radon has no colour, taste or smell. It is measured with radon detectors. Outdoors it is not a problem but, being a gas, radon can seep into buildings from the ground and can sometimes accumulate to very high concentrations.

Of the 37,500 homes measured by the RPII up to December 2009, 4900 were found to be above the Reference Level. This is just over 5% of the 91,000 homes predicted to have high radon concentrations.
