Radon Barriers

Radon is a radioactive gas which occurs naturally from the decay of uranium in rocks and soils. It is can only be detected by using special equipment as it has no colour or odour. In the open air it is dispersed to harmless concentrations, but in a confined space tiny radioactive particles can accumulate. These particles when inhaled can be damaging to cells in the lungs and contribute to the risk of lung cancer.

Radon enters a building through cracks in floors or any gaps around pipes or cables. In tends to be sucked into buildings because the internal warm air is lighter than the outdoor air.

Since July 1998, Irish Building regulations require every new house in Ireland to include some radon preventative measures. It is also advisable for older homes and buildings to check their radon levels and employ radon protection.

The Reference Level used by the Radiological Protection Institute of Ireland (RPII), above which the need for action to reduce internal radon exposure should be considered, is 200 Becquerel per metre cubed (Bq/m3).

High Radon Areas are areas where it is predicted that more than 10% of the houses have radon concentrations above the Reference Level. To the right is a map of Donegal showing the expected percentage of houses above the reference level in each area.
