ee - a anne would afford observers an opportunity to test a cloud sample of a clean weapons test and demonstrate that there was actually ° greatly reduced fallout from the weapon and would not reveal important new weapons information, Under this plan, samples would be brought to the UCRL laboratory at Berkeley, where they would be analyzed in the presence of the foreign observers. General Starbird added, however, that any observers who attended @ clean Weapons test and who are predisposed not to believe any analysis which shows a weapon to be clean would not be convinced otherwise by the demonstration. On the other hand, those who believe that the U.S. has developed a clean weapon do not need a demonstration shot to prove it to them, Mr, Libby pointed out that countries such as India are capable of conducting their own akatysis of the cloud samples and inquired why, after observing the test detonation, they should not be provided samples to analyze in their own laborator:’ General Starbird replied that certain additional weapons information could be deduced that would not be discovered af the tests were conducted under U.S, supervision at the UCRL laborato: Mr. Fleids added that each country probably would arrive at a different conclusion about the cleanliness of the weapon tested and the result would be general confusion about what the test actually proved. Mr, Libby said he did not favor holding the test since he believed the effort and money expended on it could much more profitably be spent on other projects but, if a demonstration is to be held, the foreign observers should be permitted to take the samples to their own laboratories for analysis. To prohibit this, he said, would only bring about accusations that the U.S, was attempting to censor the results of the test. . totes FOBpekes ae Oa
