HC Deb 23 June 1971 vol 819 c287W
Mr. Kinnock

asked the Secretary of State for the Environment what variations in strontium 90 levels have been recorded by his Department since 1960; and what readings, by regional location of monitoring apparatus have been given.

Mr. Peter Walker

The one aspect of this subject for which my Department is responsible is drinking water. I am sending the hon. Member a copy of the H.M.S.O. publication "Radioactivity in Drinking Water in the United Kingdom", which includes the levels from 1960 to 1966; a copy of the published results for 1967; and details, given by location of the monitoring apparatus, of the readings taken between 1968 and 1970. These give no cause for anxiety.
