Above and below: SECRET diagrams from 1956 UK Home Office Scientific Advisers’ Branch report CD/SA 72 (UK National Archives document reference HO 225/72), “Casualty estimates for ground burst 10 megaton bombs”, which exposed the truth behind UK Cold War civil defence (contrary to Russian propaganda against UK defence, which still falsely claims there was no scientific basis for anything, playing on the fact the data was classified SECRET). Evacuation plus shelter eliminates huge casualties for limited attacks; notice that for the 10 megaton bombs (more than 20 times the yield of today’s MIRV compact warheads!), you need 20 weapons, i.e. a total of 10 x 20 = 200 megatons, for 1 million killed, if civil defence is in place for 45% of people to evacuate a city and the rest to take shelter. Under civil defence, therefore, you get 1 million killed per 200 megatons. This proves that civil defence work to make deterrence more credible in Russian eyes.

Christopherson’s “Structural Defence 1945, RC450”, giving low cost UK WWII shelter effectiveness data, which should also have been published to prove the validity of civil defence countermeasures in making deterrence of future war more credible by allowing survival of “demonstration” strikes and “nuclear accidents / limited wars” (it’s no use having weapons and no civil defence, so you can’t deter aggressors, the disaster of Munich appeasement giving Hitler a green light on 30 September 1938, when Anderson shelters were only issued the next year, 1939!):
