§ 11. Mr. Frank Allaunasked the Lord President of the Council and Minister for Science if he will make a statement on new techniques recently developed for the detection of underground nuclear test explosions.
§ Mr. HoggNo, Sir. There have been no recent developments in the technique of detecting and identifying underground nuclear explosions of sufficient signifi- 236 cance which would call for a separate statement by the Government.
The Atomic Energy Authority is preparing for publication an account of the relevant scientific work on seismic research undertaken in this country.
§ Mr. AllaunWill the Minister confirm that there have been developments at Aldermaston which would make it possible now to detect all underground explosions except those so small as to be of no significance militarily?
§ Mr. HoggNo, Sir. I have seen reports in the Press to that effect, but I am informed that they are misleading.
