...getting usable energy out of the nuclear reactions that make H-bombs explode. Industrialists looking forward to atomic power are just as interested in fusion as physicists are. If controlled power can be extracted from hydrogen or other light elements, it may prove much cheaper than power from uranium...
...devote its entire heart and mind to find the way by which the miraculous inventiveness of man shall not be dedicated to his death, but consecrated to his life." His specific proposal: the big powers should "begin now and continue to make joint contributions from their stockpiles of normal uranium and fissionable materials to an international atomic- energy agency . . . under the aegis...
Telltale U-237. About 27% of the radiation came from U-237, a short-lived uranium isotope (half-life: 6.75 days) which does not exist in nature. Nearly all the rest came from elements with middle weight atoms, such as tellurium, zirconium and cerium. The content of the sample was roughly the same as that of dust that came from the great U.S. bomb exploded at Bikini on March...
Tipoff ingredient was the U-237. In the original atomic bomb of 1945 the active substance was U-235, the rare uranium isotope that fissions (splits) readily when struck by slow-speed neutrons. U-238, the abundant isotope of uranium, does not fission in this way, but when it is struck by high-speed neutrons from a sufficiently powerful detonator, it undergoes a variety of nuclear reactions. Some of its atoms split, splattering into middleweight atoms (fission products) and giving off enormous energy. Other U-238 atoms absorb a neutron, then eject two neutrons, turning into atoms of telltale...
CANADIAN MINING DEAL, one of the biggest in the country's history, will throw together Uranium King Joseph Hirshhorn's properties (TIME, Feb. 21, 1955) with Britain's big Rio Tinto mine interests. For $34 million in stocks and bonds, Hirshhorn has sold his holdings in the Blind River area (Pronto Uranium, Pater, Plum...
