HC Deb 25 July 1956 vol 557 c415
45. Mr. Watkins

asked the Lord Privy Seal what effects strontium has had upon Welsh mountain sheep; and if he will make a statement.

The Secretary of State for the Home Department and Minister for Welsh Affairs (Major Gwilym Lloyd-George)

I have been asked to reply.

In studying the distribution of radioactivity arising from fall-out, measurements have been made of the strontium 90 associated with the calcium in various biological materials. Among the representative samples of sheep bones examined, a few from very localised mountain areas in Wales have shown higher values than those from other areas. Even so, the levels are too low to have any detectable effects on sheep.
