HC Deb 12 June 1958 vol 589 cc409-10
45. Mr. Hayman

asked the Prime Minister whether he will make a statement on the high degree of radioactivity in Cornwall.

The Secretary of State for the Home Department and Lord Privy Seal (Mr. R. A. Butler)

I have been asked to reply.

The average level of radioactivity in all areas containing granite is somewhat higher than elsewhere. The level in such areas in Cornwall, in general, is no higher than this average.

Mr. Hayman

Can the right hon. Gentleman say whether radioactivity from geological sources is higher or lower than radioactivity from fall-out?

Mr. Butler

I should need to examine that supplementary question with great care and send an answer to the hon. Gentleman.
