Kerry radon week March 2012

Why is radon a problem in Kerry?

In the map of Kerry below, High Radon Areas are depicted as the brown and dark brown coloured grid squares.

A 'High Radon Area' is one in which more than 10% of homes are predicted to have radon levels in excess of the Reference Level (or acceptable level) of 200 becquerel per cubic metre (Bq/m3).

Many parts of north Kerry are designated High Radon Areas.  Tralee is predicted to have more than 20% of the homes above the Reference Level (or acceptable level).

You can search for your home address on our interactive radon map.

Even if you do not live in a High Radon Area, you still may have high levels in your home. The only way to know is to have your home tested.

We have also compiled results by county from all the measurements we have undertaken that show Kerry has amongst the highest incidence of radon in homes in the country. Of the 3660 homes tested in the county, 15 per cent (562) or one in seven are above the acceptable level including 3 per cent (117) which were measured at more than four times the acceptable level.  However, when a high level is found in Kerry it tends to be very high. The table below shows the top twenty highest radon results found in homes throughout Ireland up to March 2012. Eleven of the top twenty occur in Kerry.
