§ Mr. WigleyTo ask the Secretary of State for Wales if he will list those towns and villages in Wales in which there may be significant effects on houses arising from radon; and if he will issue guidance as to what step householders in these locations should take to minimise any dangers.
§ Mr. GristThe Welsh Office commissioned survey and that carried out by the National Radiological Protection Board to date have not revealed any towns and villages in which here may be significant effect on houses arising from radon. The surveys have demonstrated levels of radon above the action levels in very few houses but these have been included in the second phase of the NRPB survey where measurements are being taken over a period of 12 months. It is not possible to anticipate the findings of the second part of the survey the result of which should be available towards the end of the year.
Two free advice booklets "Radon in Houses" and "The Householder's Guide to Radon" have been distributed to homeowners in the surveys and are available on request.
