§ Mr. Elystan Morganasked the Secretary of State for the Environment what is the level of Strontium 90 in Cardiganshire; and how this level compares with the average level for the United Kingdom and with the level in Cardiganshire in 1965.
§ Mr. Graham PageI am informed that separate figures for Strontium 90 in drinking water—which is the one aspect of this subject for which my Department is responsible—in Cardiganshire are not available. No comparison with the average level for samples throughout the United Kingdom is therefore possible. Regular tests made on several sources in the United Kingdom for the past five years have shown that the level of Strontium 90 has remained small and has given no cause for anxiety.
