HC Deb 24 April 1958 vol 586 c86W
48. Mr. Beswick

asked the Prime Minister what official published evidence exists that no detectable increase in the incidence of leukaemia or bone cancer is to be expected from the nuclear explosions which have taken place up to now.

The Prime Minister

The view of the Medical Research Council that no detectable increase in the incidence of leukaemia or bone cancer is to be expected from the nuclear explosions which have taken place up to now is based on considered assessment of all the published literature. The matter is kept under continuous review in the light of new evidence as it becomes available.
