HC Deb 14 May 1957 vol 570 c11W
49. Mr. Mason

asked the Prime Minister if he is yet in a position to make an announcement stating how many tests are due to take place near Christmas Island.

The Prime Minister

No. It would not be in the interest of national security to give this information.

51. Mr. Boyd

asked the Prime Minister whether he will assure the House that the British nuclear weapon tests will not result in so much radioactive fall-out as to increase the incidence of bone cancer or to be detectable on instruments situated in the Union of Soviet Socialist Republics.

The Prime Minister

As I have assured the House on several occasions, the forthcoming tests, which will be high air bursts, will not involve heavy fall-out; and I am satisfied that from the medical and biological point of view the radiation effects will be insignificant. I can give no assurance that these tests will not be detectable in the Union of Soviet Socialist Republics.

58. Mr. Grimond

asked the Prime Minister what technical objections there are to a postponement of the nuclear bomb tests until further reports on the dangers can be received from the Medical Research Council and the United Nations Scientific Committee.

The Prime Minister

The mounting of a nuclear test is a major operation requiring long and elaborate preparations. Moreover, testing is part of the development and production programme, which would be severely dislocated by postponement.
