Radon measurements have been undertaken in 437 schools in Counties Galway, Mayo and Clare. The survey identified 18 schools in need of further investigation. Advice regarding remedial measures in a limited number was conveyed to the relevant school authorities and to the Department of Education.
Final results of a survey undertaken by the Nuclear Energy Board in 1989-90 indicate that about 5 per cent of houses tested in the west exceed the reference level of 200 becquerels per cubic metre. This is the level agreed by the Government above which remedial measures should be considered.
Since 1989 the Nuclear Energy Board have been undertaking measurements of radon gas in Irish homes. Work initially was concentrated in Counties Mayo, Galway and Clare as earlier surveys showed these counties to have higher levels of radon. Any householder can have a measurement carried out by the Nuclear Energy Board at a charge of £15 and a campaign to publicise this service in newspapers was undertaken in the west last year. Where screening measurements indicate a level in excess of 200 becquerels per cublic metre, householders are advised of the recommendation to reduce the concentration levels in their homes.
Since taking office I have taken a keen personal interest in the radon problem. I have ensured that the Nuclear Energy Board have had sufficient resources at their disposal to deal effectively with the problem and to follow up on initial surveys done in this field. I shall continue to ensure that priority is given to detection of radon by the Nuclear Energy Board and continued advice to those affected by it.
