The United States Atomic Energy Commicsion has concistently tried to reduce the magnitude of the fallout from atomic testing and it is cleas that the new technique of testin, underground can further greatly reduce world-wide failouc. It ic to be hoped that other nation. wiil adopt thi. procedure, even though it is sometimes difficult and more troubie. TIét does have one advantage, however, in addition to eliminating: fallout; it makes the test schedule independent of weatinex.
