§ Mr. Alex CarlileTo ask the Secretary of State for Wales if he will close Trawsfynydd lake to members of the public until a full inquiry has been carried out into the radioactivity of the lake; and if he will make a statement.
§ Mr. Gwilym JonesRegular monitoring of a range of environmental materials from Trawsfynydd lake is undertaken by the directorate of fisheries research of the Ministry of Agriculture, Fisheries and Food. This monitoring indicates that the radioactivity dose to the critical group, that is, people who consume fish from the lake and spend time on the lakeside, is well within internationally recommended safety limits. There would appear to be no reason, therefore, why Nuclear Electric should be advised to close the lake to the public.
§ Mr. Alex CarlileTo ask the Secretary of State for Wales if he will make a statement about the level of radioisotopes in Trawsfynydd lake.
§ Mr. Gwilym JonesData on levels of radioisotopes in Trawsfynydd lake are collected in the course of routine monitoring by the Ministry of Agriculture, Fisheries and Food. Results are presented in the "Aquatic Environment Monitoring Report" published annually by that Department's directorate of fisheries research. The latest issue, No. 34, item 6.10 of which refers to Trawsfynydd, is in the Library of the House.
