asked the Lord President of the Council if the Government have taken adequate steps to ascertain the more distant after-effects of the atom bomb exploded over Japan in 1945, particularly in regard to biological aftereffects; whether such findings can now be published; or whether he will consider sending a mission from the Department of Scientific and Industrial Research to Japan.

There is an American scientific mission in Japan studying this subject, And the information it collects is available to His Majesty's Government. Some of it has already been published in technical journals.
