§ Sir Peter FryTo ask the Secretary of State for the Environment what categories of information are provided by the National Radiological Protection Board to local authorities to assist them in identifying and advising individual households which may be at risk from high levels of radon gas; and what category of information on radon-affected homes is considered by the board to be confidential and not made available to local authorities. [38086]
§ Mr. ClappisonParticipation in the radon measurement programme, administered by the National Radiological Protection Board on behalf of the Department of the Environment, is voluntary. Householders who participate in this Government-funded programme are given categorical assurances that the results for their homes will be confidential to them. The NRPB is therefore not free to release individual results to any other party. However, to assist local authorities, aggregated data are routinely provided to each local authority within whose area measurements have been made. These data are given for areas defined down to the level of postcode sectors.
