I propose to take Questions Nos. 436 to 439, inclusive, together.
My Department commissioned the Radiological Protection Institute of Ireland to carry out a survey of radon levels in all primary and post-primary schools in the country. The survey, which is being conducted in three phases, involves recording the concentration of radon gas present in a school over an academic year.
The RPII recently issued results to schools that participated in the first phase of the survey. At that time the RPII advised in a press release that the results were issuing to the relevant schools and that my Department was making arrangements for remedial action to be taken where required, with priority being given to the cases of greatest need.
A total of 175 schools showed radon levels in excess of the national reference level with 13 schools showing levels that require immediate mitigation. A consultant has already been engaged to advise in relation to this task.
