For this pilot study the Health Protection Agency (HPA) worked with the Building Research Establishment (BRE) and Flintshire Council (BRE). The report describes in detail including the types of approach used in the different phases of the programme, which resulted in increased uptake of the radon measurements offered with over 46% of those offered accepting compared with some 25% from previous campaigns. The initial contact letter has been used subsequently as a model to increase the uptake in other areas of the UK where similar campaigns are underway.
The introduction of face to face advice sessions for householders with levels of radon in excess of the Action Level increased the remediation rate during the 3 years that the programme was active. The number of householders requesting further tests to check the effectiveness of remediation increased by a factor of 3 over this period in comparison to the previous 3 years. However, the remediation undertaken by these householders was only successful in around 39% of homes; improvements to future programmes to address this are suggested.
