In 1948, in response to the perceived threat of atomic war, the British government embarked on a new civil defence programme. By the mid-1950s, secret government reports were already warning that this programme would be completely inadequate to deal with a nuclear attack. The government responded to these warnings by cutting civil defence spending, while issuing apparently absurd pamphlets advising the public on how they could protect themselves from nuclear attack. Historians have thus far sought to explain this response with reference to high-level decisions taken by policymakers, and have tended to dismiss civil defence advice as mere propaganda. This paper challenges this interpretation by considering the little-known role of the Home Office Scientific Advisers' Branch, a group of experts whose scientific and technical knowledge informed both civil defence policy and advice to the public. It explores both their advisory and research work, demonstrating their role in shaping civil defence policy and showing that detailed research programmes lay behind the much-mocked government civil defence pamphlets of the 1950s and 1960s.

61 The report of the British Mission to Japan, published in 1946, had explained the effects of blast, fire and radiation on various structures – including shelters, houses and factories – and on people, and had used the information to estimate homeless and casualty figures for an attack on a typical British city. See The Effects of the Atomic Bombs at Hiroshima and Nagasaki: Report of the British Mission to Japan, HMSO, 1946. Scientists such as William Penney, who in 1948 was directing research at Fort Halstead in Kent (the precursor to the Atomic Weapons Research Establishment at Aldermaston), were also key sources of atomic information. Penney had worked on the development of the first atomic bomb at Los Alamos, had been one of two Britons in the observer plane at the bombing of Nagasaki and had also been invited to take part in the United States' atomic tests at Bikini in 1946, along with several other British scientists.

Their study shows that the DRPC did not initially have complete access to atomic information and were excluded from atomic decision-making, but later became more involved in atomic policy.

78 The delay between the suggestion in 1955 that a pamphlet should be prepared and the final publication of the pamphlet appears to have been due to uncertainty about what the pamphlet should contain and how it should be distributed. The Berlin Crisis in 1961 gave a renewed impetus to the preparation of a pamphlet for the public, and initially the Home Office proposed to distribute twenty million free copies to British households in the event of a crisis. Concerns about cost, speed of printing and the possibility of causing public panic led to a decision in early 1962 to market the pamphlet as a training booklet for members of the civil defence services while putting it on sale to the public in peacetime. Additional material was to be issued to the public via the press in the event of an emergency.
