...eventual Communist takeover of all Asia, shaking hitherto staunch anti-Communists in their resolve-and giving other nations nuclear ideas. Thanks mostly to technology supplied by the U.S., a dozen or more countries-among them Egypt, Israel, India, Japan, West Germany and Mexico-possess reactors capable of producing uranium or plutonium. The U.S. Atomic Energy Commission estimates that nowadays, for an investment of $50 million, a country can establish enough plutonium production to manufacture one crude weapon a year. Communist China's example, as President Johnson puts it, "tempts other states to equal folly...
...first, U.S. avithorities seemed to agree that the Chinese must have used plutonium as their fissionable material. The process of separating U-235 from natural uranium requires enormous amounts of electric power, and China is power poor. Plutonium, on the other hand, is made in nuclear reactors, which require little external power. China is known to have reactors, and both air surveyance and ground spying have reported a large reactor complex near Paotow in Inner Mongolia. Japanese students of Chinese activities also agreed that China must have used plutonium because it lacked the electricity needed for the production...
...defection of Western-trained scientists from such atomic centers as Caltech and France's Curie Institute, the Chinese have the scientific know-how to continue. Because of Russian aid from 1950 to 1959 (when the Moscow-Peking split first fissured), they also have a network of operating uranium mines, at least four nuclear reactors, a raft of Soviet-trained technicians, and a rudimentary basic industrial plant that can furnish most of the products needed to maintain a small atomic-bomb program...
...that only one question in ten reaches an exam in its original form. For example, when students were asked to decide whether "Alpha-particle emission with long half lives is a property peculiar to a) compounds, b) heterogeneous matter, c) the heavier elements, d) the lighter elements or e) uranium," many students interpreted "peculiar" as meaning "strange or unusual." The question (answer: c) the heavier elements) was clarified by replacing "peculiar" with the phrase "found only...
HALL OF SCIENCE states its age limit bluntly with an entrance only 5 ft. high. The youngsters can prospect for uranium, work electrical generators by pedaling bicycles, play pinball with neutrons and uranium atoms, and measure their own weight in atoms...
