HC Deb 05 February 1963 vol 671 c46W
91. Sir C. Taylor

asked the Parliamentary Secretary for Science what evidence there was during recent snow falls of snow being contaminated by strontium 90; and what was the degree of contamination.

Mr. Denzil Freeth

The measurement of strontium 90 levels is, for technical reasons, a lengthy process and no figures are as yet available of strontium 90 levels in the recent snowfalls.
