Snarled Threads. Seven months before the outbreak of World War 11, scientists in the U.S. learned with alarm that physicists in Germany had succeeded in bringing about atomic fission. Shortly afterward, the U.S. incurred the first major installment of its massive debt to Hungarian-born scientists. Physicist Leo Szilard, leaping in thought from laboratory fission to atomic bomb, set out to urge the U.S. Government to get an atomic-research project going. Reasoning that a letter to President Roosevelt would have maximum impact if signed by Einstein, Szilard recruited his fellow Hungarian Edward Teller to chauffeur him out to Peconic...
...also honored a famed scientist last week: Physicist Niels Henrik David Bohr, one of the fathers of atomic fission. President Eisenhower went to Washington's National Academy of Sciences to address the meeting as Bohr received the first Atoms for Peace Award, a gold medal and a $75,000 tax-free "honorarium" put up by the Ford Motor...
...contaminate whole provinces and nations. Beyond that, the meaning of the scientists' report was that the U.S. is approaching a major development in atomic power for peace: how to produce the vast energy of H-bomb fusion-perhaps controlled energy-by means other than using radioactive, atomic fission to set off the fusion process...
...about 3% of the natural radiation exposure." Another Libby example: a person moving into a concrete-block house in certain countries may get up to 100 times as much additional radiation from naturally radioactive elements in the concrete as he is getting from present fallout. He recognizes that fission products from past tests are still stored in the stratosphere and that they will soon be joined by the products of new tests. This is not worrisome either, he says: "If tests were to continue until 1983 at the rate of the past five years, [fallout radiation] levels...
...large-scale testing. Italian scientists, from Roman Catholics to Communists, agree that too little is known to justify taking risks with the world's health. Most German scientists feel the same way. The Japanese, who get fallout from both east and west, are especially emphatic. They believe that fission products now in the stratosphere may be dangerous already and will surely become so unless the testing is stopped. Says Physicist Mitsuo Taketani of Rikkyo University: "The U.S. and the U.S.S.R. are not testing now. They are conducting nuclear bomb and weapons maneuvers. The whole population of the world...
