Radon is the greatest source of radiation exposure to the public. In Ireland, it is estimated that approximately 7% of the national housing stock have radon concentrations above the Reference Level of 200 Bq m⁻³. A radon test can be carried out to identify homes with radon levels above the Reference Level. However there is no health benefit associated with radon testing unless it leads to remediation.Surveys to establish the rate of remediation in Ireland, that is the proportion of householders who having found levels of radon above the Reference Level proceed to carry out remediation work have been carried out in 2011 and 2013. Reasons for not carrying out remediation work were also investigated. In 2015 the survey was repeated to establish the current rate of remediation and reasons for not remediating. This report presents the results of that survey. It also compiles the data from all three surveys to identify any trends over time.The rate of remediation is an important parameter in estimating the effectiveness of programmes aimed at reducing radon levels. Currently the rate of remediation is 22% and the main reasons householders gave for not remediating were not certain there is a serious risk and concern about the cost of the work. In Ireland, this figure of 22% will be now used as a baseline metric against which the effectiveness of its National Radon Control Strategy will be measured over time.
