Grid squares in which the predicted percentage of homes is 10% or greater are called High Radon Areas. This map is used to predict the percentage of homes in each 10 km grid square with radon concentrations in excess of the national Reference Level of 200 bequerel per cubic metre (Bq/m3).

A spot height may be expressed as AOD for "above ordnance datum". Usually mean sea level (MSL) is used for the datum. Malin Ordnance Datum Derivation of vertical height or depth (in metres) In the Republic of Ireland, OD for the Ordnance Survey of Ireland is Malin Ordnance Datum: the Mean Sea Level (MSL) at Portmoor Pier, Malin Head, County Donegal, between 1960 and 1969. 5731 EPSG Projection 5731 - Malin Head height Metres Derivation of Altitude OD based on Mean Sea Level, Malin Head 1960-1969 ESRI Shapefile 10.x Informatics Environmental Protection Agency Data Manager +353-53-9160600 +353-53-9160601 PO Box 3000 Johnstown Castle Estate Wexford Co.

Houses were chosen at random to give a uniform distribution across the country. In all, over 11,000 homes were measured.The results were used to predict the percentage of homes in each 10 km grid square with radon concentrations in excess of the national Reference Level of 200 bequerel per cubic metre (Bq/m3). The radon map has five categories: less than 1 per cent, 1 to 5 per cent, 5 to 10 per cent, 10 to 20 per cent and greater than 20 per cent. If you live in an area designated as 'greater than 20%', this means that more than 20 per cent (1 in 5) homes in that grid square are likely to have radon concentrations above the Reference Level.
