...Bernardino, Calif., he made a sentimental journey to the Platt Building, where he operated an elevator as a boy 39 years ago, but his remarks about Goldwater were decidedly unsentimental. It would be awful, he said, if both Barry and Red China had the atomic bomb at the same time...
...neat theory was destroyed when the AEC announced a preliminary analysis. That report indicated that the Chinese test used "a fission device employing U-235." Unless the Russians in friendlier years got the Lop Nor bomb work started with a goodly amount of U-235, the Chinese must somehow have scraped up the electricity to make the stuff, or less likely, invented a new and better process...
Clicking Counters. Except for describing the bomb as weak, U.S. authorities at first released no figures, and the Weather Bureau, which traced the radioactive cloud, reported its directional progress only, making no comment on its intensity except to say that it was not strong enough to be at all dangerous. But in bomb-bitten Japan, where radiation watching is something of a national hobby, rooftop Geiger counters started clicking ominously. Scientists caught rain water to measure its activity, and jets brought samples down from the sky. About 30 hours after the explosion the radiation count at Niigata, 180 miles north...
...Chinese depended on an implosion (inward-striking detonation) of chemicals to compress their U-235 and make it fission. Such a device is more effective than shooting two chunks of fissionable material toward each other in an apparatus like a gun barrel, as was done in the U.S. bomb exploded over Hiroshima. The U.S. also used the implosion method in its earliest nuclear weapons. Although a surprising number of commentators assumed that use of implosion showed advanced skill by the Chinese, the AEC did not agree. "The low yield of the test," it said, "coupled with other information obtained from...
When Red China crashed the nuclear club, its A-bomb test blast echoed through all the world's capitals. And it roused once again the specter of a dead and devastated world. Scientists and laymen alike have long feared that the aftermath of a nuclear attack would be a desolation of blasted, baked and radioactive wasteland. What life survived the initial holocaust, it was agreed, would surely succumb to the longer-lasting hazards of atomic radiation. So far, the best proving grounds for such theories are Bikini and Eniwetok, the two Pacific atolls that were clobbered by some...
