HC Deb 06 March 1990 vol 168 cc564-5W
Mr. Alex Carlile

To ask the Secretary of State for Wales what assessment he has made of the health implications for people eating substantial amounts of fish from Lake Trawsfynydd; and if he will make a statement.

Mr. Grist

Annual assessments are made of the maximum dose of radioactivity received by people eating fish from Lake Trawsfynydd. The latest information shows that only 7 per cent. of the internationally recommended dose limit of 1 milliSievert was received in 1988 by the most exposed groups.
