...Pointed out that strontium 90 derives not from the testing of big H-bombs alone-which Stevenson would stop-but from any process of nuclear fission. "Thus the idea that we can 'stop sending this dangerous material into the air,' by concentrating upon small fission weapons, is based upon apparent unawareness of facts...
Boos for Ike. The Springfield response was good enough to get him really steamed up for California. In San Francisco he poured on the sarcasm ("You've got to respect [Eisenhower's] clear and forthright opposition to inflation, deflation, fission, fusion and confusion, doubt, doom and gloom, fog and smog"). And once again he asked: "Are we seriously asked to trust . . . the decision over the hydrogen bomb to ... Nixon?" And once more, the crowd roared: "No!" In Los Angeles that night, 25,000 aggressive, confident Democrats caught the new spirit as Adlai carried on at Gilmore Field. They...
...estimates of strontium yield from a given fission energy are low by a factor of four, due to the use of older figures; recent, more accurate figures were not available at the time the report was issued...
...scientists decided that between one and three neutrons are produced per fission. Russian scientists settled on the figure of between two and four neutrons...
...Fissioning in the Subway. Another key question was whether uranium atoms ever fission spontaneously-an important factor in weighing the feasibility of practical bombmaking. Theorists said that spontaneous fission ought to take place, but excellent experimental men in the U.S. were unable for a considerable time to prove that it did. The first to prove it (in 1940) were two young Russians, Flerov and Petrzhak, who did their work (to protect their experiment from the intrusion of cosmic rays) in the depths of Moscow's ornate subway...
