Auditing the cost‐effectiveness of radon mitigation in the workplace

Radon is a natural gas which can build up underneath buildings. The International Agency for Research on Cancer has found sufficient evidence to classify radon as harmful to humans. The National Radiological Protection Board (NRPB) has identified areas in the UK where radon levels are above average. Northamptonshire is one such area, where the NHS was required to set up a radon mitigation programme to reduce the potential health hazard to its 11,189 employees, employed in 82 separate sites. Calculates the dose saving achieved and the associated costs and attempts to derive a value for the cost‐effectiveness of the programme, compared to a programme recommended by the NRPB to reduce patient doses from dental X‐rays in the UK. Also examines recent domestic remediation initiatives investigated by researchers in Spain, the USA, Sweden and Canada. The methods used by Colgan and Gutiérrez (1996) to measure reductions in radon levels and to calculate associated annualised costs were used to analyse the results of the Northamptonshire NHS programme which produced an estimated cost of £680,000 per lung cancer saved. Reports on the costs and potential benefits delivered by the radon mitigation programme in Northamptonshire. Also discusses some of the wider policy implications for management, particularly in multi‐site public sector organisations where value for money in an environment of limited funding is an increasing pressure.
