Ruggles and Kramish found that as far back as the 1920s, competent Soviet physicists were contributing to the birth of nuclear physics. In 1938, when the critical news came from Germany that neutrons make uranium atoms fission (split in two) to yield enormous energy, Russian scientists reacted as excitedly as their colleagues elsewhere, working with impressive skill to establish the same key facts which would decide whether large amounts of nuclear energy could be got from uranium...
...important question was whether a splitting uranium atom gives off enough free neutrons to sustain a chain reaction...
HAPPY JACK URANIUM MINE, one of richest in Colorado Plateau, has been bought by Texas-Zinc Mineral Corp., uranium subsidiary of Texas Co. and New Jersey Zinc. Fletcher Bronson and family originally bought mine for $1,000 as copper prospect in 1946, once turned down $15 million for it. Texas-Zinc is mum on purchase price, but has already started building processing mill at Mexican Hat to handle ore from Happy Jack and other southeastern Utah mines...
...URANIUM ORE PRODUCTION in the U.S. is up to nearly 3,000,000 tons annually (v. 70,000 tons in 1948), thus making U.S. the free world's leading producer, says AEC Raw Materials Director Jesse C. Johnson. U.S. ore output will eventually climb to 5,000,000 or 6,000,000 tons annually...
...quick-settling coral dust. First radioactive material from the May 21 explosion was brought home by the tuna boat Stiruga Maru. Analyzed by Dr. Kenjiro Kimura of Tokyo University, it proved to contain a familiar array of fission products-ruthenium, rhodium, tellurium, iodine, cerium, neodymium, etc.-as well as uranium 237 and neptunium 239. This combination of elements indicated that the explosion was the "fission-fusion-fission" type, which gets much of its energy from the fission of normally inactive uranium...
