The fallout issue came to a head when Los Alamos scientists wanted to add an additional shot to produce vital data for the 1954 thermonuclear test series. Although the President and the Cammission approved the shot, one of the Commissioners was so concerned about fallout that he requested a full-scale review of "the highly interrelated public relations and safety problems" the Cammission had created in Nevada.78 The Commission immediately launched an investigation cf the sheep deaths and a full-scale review of Nevada testing. Camission scientists, "fully aware that the future of continental testing might hang on the results," concluded that fallout aid not cause the sheep deaths. They remained silent on whether it might have been a con- tributing factor and in. public announcements the Commission "glossed over the fact unanimous, "*? that scientific opinion on the question was net The review committee decided that continental testing should continue but suggested several methods to reduce fallout “=m test shots. The Commission adopted most of the suggestions integrated them into planning for the next continental series. anc
