The cost effectiveness of radon remediation programmes in hospitals, schools and homes in radon affected areas in the UK.

This analysis was carried out, first for Health Service properties in Northamptonshire, and then for schools and domestic properties. Comparison of the three programmes showed that the programme in schools was the most cost effective, but that a completed programme in domestic properties would be almost as effective. However, in the UK, only 10 % of those who discover raised radon levels have so far organised remedial work, greatly reducing the cost effectiveness of the domestic remediation programme. It was found that it was four times more expensive to remediate Health Service properties compared to a completed programme in domestic properties. The results were close to theoretical predictions made for domestic properties in other countries.
