FOREWORD
The material in this book falls into two categories: (1) a popular version in terms understandable to the layman of technical data published in scientific literature in this country and abroad, and widely known among scientists everywhere; and (2) technical conclusions reached by deduction based on these published facts and theory, for which I assume the sole responsibility. In doing so, I wish to make it emphatically clear that I have had no access to any classified information on the current hydrogen-bomb program, and also that whatever access I had to H-bomb information during my stay at Los Alamos in the spring and summer of 1945 was strictly limited to the somewhat vague and general discussions carried on there in 1945 and earlier.
I hereby take the opportunity to express my profound appreciation to Dr. James G. Beckerley, Director of Classification, Atomic Energy Commission, Washington, D. C., and to Mr. Corbin Allardice, Director, Public Information Service, of the AEC’s New York Operations Office, for their generous cooperation in clearing this manuscript for publication. It must be strictly understood that any such clearance merely means that the AEC has “no objection to publication” on the grounds of security. It does not in any way vouch for the accuracy or correctness of the book’s contents.
