To ask the Secretary of State for Wales what measures are being taken to help those people in Clwyd whose homes are at risk from radon seepage; and if he will make a statement.

The results of further research, to delineate more accurately areas where radon levels may be higher than average, are expected in the spring of 1994. In the meantime, free measurement of radon levels is available to concerned householders living in areas where concentrations may be elevated. Home renovation grants may be available for homes where radon concentrations are found to be above the Government action level of 200 bq/cu m.
