HC Deb 14 February 1951 vol 484 c64W
50. Mr. Blackburn

asked the Minister of Defence what arrangements he made to ensure the presence of military and scientific British observers at the recent atomic tests in the United States of America.

Mr. Shinwell

None. Since the passage of the United States Atomic Energy Act of 1946, it has not been the practice of the United States Government to admit non-American observers to atomic tests.
