It is estimated that approximately 100 000 Irish homes have radon concentrations above the reference level of 200 Bq m(-3). To minimise the number of new homes with this problem, building regulations require that all new homes built since July 1998 in high radon areas are installed with radon barriers during construction. Measurements on local authority homes in a number of high radon areas have allowed the impact of these new regulations to be assessed. In County Cork a reduction of up to 70% in the mean radon concentration was observed in homes built since 1998 relative to those built before this date. A reduction in both the number of homes exceeding the reference level and the maximum concentration measured in homes was also measured. Homes exceeding the reference level were remediated with the use of an active sump. The results of this remedial work are also presented and show that the mean reduction in radon concentration achieved was 92%.
据估计，爱尔兰约有100000户家庭的氡浓度高于200贝克勒尔/立方米的参考水平。为尽量减少出现这一问题的新建房屋数量，建筑法规要求自1998年7月起在高氡地区建造的所有新建房屋在施工期间安装氡屏障。对一些高氡地区地方当局房屋的测量使得能够评估这些新法规的影响。在科克郡，观察到1998年以来建造的房屋相对于该日期之前建造的房屋，平均氡浓度降低了70%。还测量了超过参考水平的房屋数量以及房屋中测量到的最大浓度的降低情况。超过参考水平的房屋通过使用主动集水坑进行了修复。还介绍了这项修复工作的结果，结果显示实现的氡浓度平均降低了92%。
