After US, British, Swiss and Canadian Scientific Missions had gone to Hiroshima and Nagasaki, Japan 1945 and '46, and then as a result of experiments carried first ~Shoeburyness, Essex and latterly Orfordness, Suffolk, 1947-56 new policies were drawn up by HM Governments. In 1948 an "Interdepartmental Conference" was called for and met in the temporary Offices of the Home Office at 10 Old Bailey on Wednesday l9 May starting at l500hours. At this Conference were Civil Servants from the Home Office, Ministry of Defence, Ministry of Transport, Ministry of Fuel and Power, Ministry of Supply, Ministry of Works and from the Ministry of Health. An advisor from the Royal Geological Society also attended. One result of that Conference was a Home Office sponsored survey of all known existing shelters remaining from the 1939-45 war (Item 370) and in addition, any other underground structures, be they Caves, Caverns, Tunnels or Mines that could be used in the event of any future (from that date 1948/9) conflict that were within a "reasonable distance of an Urban Area".
