Radioactive Hornets. Brookhaven scientists discovered that ordinary hornets accumulate barium in their bodies. Since radioactive barium is one of the products of uranium fission, they intend to place hornets at key positions around Brookhaven's nuclear reactor. If the hornets become radioactive, the scientists will know that fission products are getting loose...
...profit to $32 million, boosted its quarterly dividend from 50? to 62½?. Wheeling Steel kept to its regular rate ($1 a quarter), though its earnings had jumped to $23.24 per common share (v. $18.66 last year), nearly half the current market price of its stock. Even tiny Barium Steel, which had never paid a dividend, declared one of 10% in stock...
...newsmen knew what that meant. It meant the first big postwar strike. Behind the door on the mezzanine of Detroit's Barium Hotel, 200 representatives of the C.I.O.'s United Automobile Workers had voted to stop all production at giant General Motors Corp. the next morning...
...uranium nucleus splits into barium and krypton atoms, which are highly excited, unstable and artificially radioactive. They throw off gamma and beta radiation, and finally, in an effort to lose mass, they spout neutrons. If these neutrons are slowed by such substances as graphite, paraffin, heavy water or ordinary water, they will touch off other uranium nuclei. In a tiny fraction of a second the reaction will run through a good-sized sample of uranium, containing trillions of atoms, and the result will be a cataclysmic blast...
Puzzle to Fission. Late in 1938 a distinguished German chemist named Otto Hahn, of Berlin's Kaiser Wilhelm-Institute, was bombarding uranium with "slow" neutrons of low energy. As one of the end products, he identified barium. This puzzled him, but he published a diffident note on it in Naturwissenschalfen...
