Radon in dwellings: the national radon survey: Carlow, Donegal, Kildare, Kilkenny, Laois, Leitrim, Longford, Meath, Offaly, Roscommon, Sligo, Waterford Westmeath and Wexford.

摘要

This report presents the results of the second phase (for the National Radon Survey carried out by theudRadiological Protection Institute of Ireland. The counties included in this phase are Carlow, Donegal,udKildare, Kilkenny, Laois, Leitrim, Longford, Meath, Offaly, Roscommon, Sligo, Wateiford, Westmeathudand Wexford. The average radon concentrations for the houses measured in these counties ranged fromud63 to 147 8q/m3 with individual values as high as 1562 8q/nl. The measurement data were grouped onudthe basis of the 10 km grid squares of the Irish National Grid System and used to predict the percentageudof dwellings in each grid square which exceeds the Reference Level of 200 8q/m:l. Grid squares whereudthis percentage is predicted to be 10% or higher are designated High Radon Areas. The health effectsudof exposure to high radon levels are discussed and recommendations are made regarding both new andudexisting dwellings.
