As to fertility, it seems somehow inconsistent that a Japanese doctor working with a group that was smaller in terms of statistical significance should come up with such a detailed analysis of spermatozoa production after irradiation of the Lucky Dragon fishermen, while the AEC-Brookhaven teams apparently felt it unnecessary to pursue this area with the irradiated Marshallese and Americans. While the Committee might yield to the cc. sideration of the private and personal nature of the tests and examinations connected with such studies, it is unusual that the subject was never even discussed except generally in terms of genetics, and then, again, in terms of statistics. Conclusions The circumstances that led up to and followed the detonation of "Bravo" on a clear March morning in 1954 are starkly illustrative of how circumstance, time, error and fortune can all combine to produce an historical event; in this case a tragic one, The location of the testing site itself was a major factor, in that its placement provided the flexibility necessary for the detonation of large yield weapons, and the safety necessary should anything go wrong. It was in a sense equivalent to the Nevada site, which provided the same flexibility and safety for smaller yield weapons. Unfortunately, unlike Nevada, there was no Public Relations or information program, and no monitors living with the people. Nevada, tests were conducted to produce small amounts of local fallout. In In the Marshalls, however, the world's biggest hydrogen bomb explosion, to that time, was detonated on the ground. In Nevada, it was boasted, they could practically control where the fallout went. to go with an imcomplete picture of the wind. "unexpected," At Bikini, someone made the decision The wind shift was not Since nothing was kn-wn about the upper level of wind, Furthermore, the test danger zone in the Pacific was cut off at its eastern boundary to 1014758 #90
