Radon in dwellings in selected areas of Ireland

Technical Report:

Abstract

This report presents and interprets the results of surveys of domestic radon concentrations carried out by the Radiological Protection Institute of Ireland between 1989 and 1992. Data from low-density monitoring surveys in various counties are presented. The highest seasonally-corrected radon level found in any of the 1755 dwellings surveyed was 2399 Bq/m{sup 3}. This is twelve times the national Reference Level of 200 Bq/m{sup 3}, and corresponds to an annual radiation dose to occupants of the house of 60 mSv, three times the maximum dose which radiation workers are allowed to receive under internationally-accepted standards. Statistical evaluation of the data has allowed classification of 10 km grid square areas on the basis of the predicted proportion of houses in each grid square with radon levels in excess of the national Reference Level, 200 Bq/m{sup 3}. The most affected areas occur in counties Mayo and Galway, and to a lesser extent in south-east Cork city. In county Galway six grid squares are predicted to have more than 20% of houses with radon concentrations in excess of 200 Bq/m{sup 3}. In the most affected grid square 30% of houses are predicted to have radon concentrations in excess of this level. It is  More>>

In the most affected grid square 30% of houses are predicted to have radon concentrations in excess of this level. It is important that householders in these areas be strongly encouraged to have the radon levels in their houses measured in order to identify the individual houses in which remedial measures are required. The risk associated with longterm exposure to radon has been calculated using the latest risk factor recommended by the International Commission on Radiological Protection.}
