§ Mr. Barry JonesTo ask the Secretary of State for Wales how many measurements he has made of radon concentrations in dwelling houses in Wales; what plans he has to make further radon measurements and if he will make a statement on radon levels in dwelling houses in Wales.
§ Mr. Nicholas BennettOver 1,000 dwellings are included in a survey of radon levels in Wales which the National Radiological Protection Board is carrying out on behalf of the Department. Preliminary indications are that most Welsh homes are not adversely affected by radon although a very small perecentage of houses may have levels of radon above the action level.
The full results of the survey are expected shortly and I will consider the need for further investigation at that time.
