HC Deb 06 June 1957 vol 571 cc126-7W
65. Mr. Grimond

asked the Prime Minister what advice he has received as to the danger of fall-out from tactical atomic and nuclear weapons; and how it compares with that from nuclear bombs.

The Prime Minister

It is impossible to make a comparison in the terms of the hon. Member's Question. The amount and behaviour of fall-out depends on such variable factors as the design of the weapons, the height of burst, and the weather.
