The costs and benefits of radon remediation programmes in existing homes: case study of action level selection.
Radon gas can be present within buildings at sufficiently high levels that it becomes a health risk. Such levels can be reduced, and so radon remediation programmes in the home in UK Affected Areas should result in reduced risks to the population. This paper considers the benefits and costs of the domestic radon remediation programme in Northamptonshire, UK, and considers the implications of the choice of Action Level, in view of the adoption of different levels in many countries. A programme with a higher Action Level will cost less, and target those most at risk, but will be less cost effective. In addition, a higher Action Level leaves a higher residual dose and risk to the remaining population. Such doses are higher than and inconsistent with the radiation dose limits for the general public in the EU Basic Standards Directive.
