§ 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.
