In Ireland radon is a significant public health issue and is linked to up to 250 lung cancer deaths each year. Much work was carried out to address this issue during the 20-year period from 1992 to 2012. Despite this, the Government recognised that a cross-Agency approach was required to comprehensively address this problem and subsequently, the four-year National Radon Control Strategy (NRCS) was launched in 2014. This paper summarises the highlights of the work carried out to implement the NRCS between 2014 and 2018 and it also sets out the research carried out during this period to underpin this work.
