§ Mr. BeithTo ask the Secretary of State for the Environment whether he will make a statement about the exceptionally high radon levels found in tap water in Alnwick, Northumberland.
§ Mr. TrippierA survey of tap water, organised by researchers at Bristol, is currently being conducted at secondary schools round the country. The survey involves the use of a simple kit to test for radon. A single sample from a school in Alnwick was found to contain radon activity of 65 bq/1. I am advised by the National Radiological Protection Board that this result is not a cause for concern.
§ Mr. NichollsTo ask the Secretary of State for the Environment what has been the outcome of the recent publicity campaign in Cornwall and Devon relating to radon in homes.
§ Mr. BaldryI launched a publicity campaign on 11 March to encourage householders in Cornwall and Devon to take advantage of the Government-funded free radon measurement service, which is available on request to householders throughout the two counties. My Department has produced a leaflet, "Radon in Houses", which has been distributed to all households in Cornwall and Devon.
Seven hundred and fifty thousand copies of the leaflet have been sent out. The house-to-house leaflet drop was backed up by a widespread poster campaign. Posters have been displayed in libraries, citizens advice bureaux, DIY shops, estate agents etc, and additional leaflets were made available through these outlets. 160 copies of a Braille version of the leaflet were sent out through the blind welfare officers of the two counties. A public service announcement was recorded for use by local radio stations.
I am pleased to be able to tell my hon. Friend that the campaign has been a resounding success. The leaflet has a tear-off slip to enable householders to apply to the National Radiological Protection Board (NRPB) for a radon measurement. NRPB carries out radon measurements for Government. Up to the present, over 72,000 requests have been received from householders by the board. All those applying will receive a response within four weeks, and the radon detectors themselves within two months, Over 50,000 measurements are already in progress.
Cornwall and Devon make up the only area of the country which has formally been designated by the NRPB as a radon affected area. About 12 per cent. of homes in the region may have radon concentrations exceeding the level at which householders are advised to take action to 167W reduce it; this is a much larger proportion than anywhere else in the United Kingdom. Long-term exposure to radon increases the risk of contracting lung cancer.
If the results show that the Government action level is exceeded, householders are advised to undertake the necessary remedial measures, which can usually be carried out effectively for relatively modest cost. Advice on remedies is given in the Department's free leaflet, "The Householders' Guide to Radon", a copy of which is always provided with the radon survey results. Local authorities may give discretionary house renovation grants for radon remedial works, subject to a test of resources.
I most sincerely urge all householders in Cornwall and Devon to accept the advice to have their houses measured for radon.
