Dr. ThomasTo ask the Secretary of State for Defence if he will list those nuclear tests since May 1979 of which he has knowledge, their location and kilotonnage and the countries that performed them.
§ Mr. Archie Hamilton[holding answer 8 December 1989]: The Government do not hold such information in an unclassified form. The details of all British nuclear tests are included in the US Department of Energy publication "Announced United States Nuclear Tests", copies of which have been placed in the House of Commons Library. Other organisations, such as the Stockholm International Peace Research Institute, provide their own estimates of the numbers of nuclear tests.
