As stated in my reply to Question No. 72 of 26 November, it would not be practicable in the current budgetary circumstances to provide for Exchequer funding of a radon remediation grant scheme in respect of domestic dwellings.
The carrying out of radon remediation works, where considered necessary in respect of private houses is a matter for the householder. My Department's booklet, Radon in Existing Buildings – Corrective Options, provides advice on a range of appropriate remediation options. For example, improved ventilation all year round would be an immediate and cheap action to prevent build up of radon gas in the home.
My Department is developing guidelines for local authorities that will recommend a programme of testing for radon in existing rented housing stock, excluding flats above ground floor level. The programme will be prioritised in areas where high radon levels are identified by the RPII and will involve remediation works by the local authorities where necessary. These guidelines will be issued in the near future.
