§ Mr. Jonathan EvansTo ask the Secretary of State for Wales how many homes in Wales are estimated to have radon gas contamination above 200 becquerels per cubic metre of air.
§ Mr. Gwilym JonesThe National Radiological Protection Board survey estimates that up to 3,000 homes in Wales may have radon levels above the Government action level of 200 becquerels per cubic metre of air.
As measurements are completed, householders whose homes are found to have concentrations above the action level, (which is half that recommended by the European Commission), are advised of the actions which they should consider.
The results of further research, to more accurately delineate areas where concentrations may be higher than average, are expected in the spring of 1994. Meanwhile, free tests of radon levels are available to concerned householders living in areas where concentrations may be elevated.
