§ Mr. BoswellTo ask the Secretary of State for the Environment what information he has on the causes, incidence and location of abnormally high concentrations of radon gas in domestic homes; and what action he intends to take further to assess and mitigate consequent problems for human health.
§ Mr. David TrippierI refer my hon. Friend to the free booklet issued by my Department, the "Householders' Guide to Radon". A second edition is to be issued shortly. Further information is given in the statement on radon in houses, published by the National Radiological Protection Board (NRPB) in documents of the NRPB, volume 1, number 1, January 1990. Copies have been placed in the Library of the House. My Department is continuing to fund research on the distribution of homes with high concentrations of radon, on ways of reducing the radon levels, and on the effects of radon on human health.
