...taken on by the newly formed Institute of Nuclear Studies at the University of Chicago, where he became fascinated by the faint natural radioactivity that pervades the atmosphere. A significant part of this activity comes from carbon 14, an unstable carbon isotope formed when cosmic rays hit nitrogen high in the atmosphere...
...Skyrocket, a speck of dirt in the ... tank or in any of the myriad tubes and lines, and the little research ship would be blown to dust. Two models of the Air Force's X-I . . . had blown up in launching last year . . . The pressurizing gases-helium and nitrogen-were sieved through Kotex . . . That explained why I had seen cartons of the incongruous supplies stacked in the hangar...
...Manhattan, Mattei signed contracts with Phillips Petroleum Co. and Union Carbide & Carbon Corp. for their processes and help in building a $75 million synthetic-rubber plant at Ravenna, in the Po Valley. It will turn out 35,000 tons of GR-S rubber and 350,000 tons of nitrogen fertilizer annually from nearby methane deposits. The plant will be not only the first synthetic-rubber factory in Italy but the first in Europe to make rubber from natural...
...forms vast amounts of nitric acid out of atmospheric oxygen, nitrogen and moisture. There may be enough of it to acidify the rain over large areas, with adverse effects on vegetation...
...Neutrons from an H-bomb turn atmospheric nitrogen into large amounts of radioactive carbon-14, whose half-life is 5,600 years. Absorbed by plants, it eventually enters the tissues of animals and humans. Results: unpredictable...
