§ Mr. RedmondTo ask the Secretary of State for the Environment (1) how many households in Yorkshire have been recorded as being over the recommended safety limit in respect of radon; and if he will list their locations;
(2) if he will list any sites in Yorkshire that have been identified as being over the safety limit in respect of radon; and what radiation levels were recorded.
§ Mrs. Virginia BottomleyThe National Radiological Protection Board surveys in the three Yorkshire counties have led to the discovery of one house, in west Yorkshire, with a radon concentration at the action level at 400 bequerels per cubic metre. In the county as a whole, concentrations are almost exactly the national average.
