Thin strips of radiation-sensitive film, to detect over-exposure to ionizing radiation, will be worn by some University employees starting this morning. The Radiation Protection Program provides the wrist and chest film badges which are to be worn by people working in radiation-sensitive laboratories and other areas...
...detect DNA and RNA, the Army team used acridine orange, a fluorochrome dye that easily unites with the nucleic acids and shines brightly under ultraviolet light. Result: the higher the cell's nucleic acid content, the more intense the fluorescence (green to yellow for DNA, red for RNA). After a few hours of training, a skilled cyto-technologist can spot malignant cells by the intensity of fluorescence he sees in his microscope...
...proposal soon ran into trouble for two reasons: 1) the Russians demanded veto power over the makeup and movements of inspection teams on Russian territory, thus rendering inspection worthless; 2) U.S. scientists discovered that they had seriously overestimated the ability of inspectors to detect underground explosions. Alarmed by the miscalculation, the Pentagon, the Atomic Energy Commission and some members of the Joint Congressional Committee on Atomic Energy urgently asked President Eisenhower to modify the U.S. offer lest the U.S. get tied to a crippling agreement that an enemy could violate without detection...
...construction work by Army engineers goes on at Thule and Clear, Air Force engineers, electronics contractors and subcontractors are building monster radar screens, each half again as long as a football field, tough enough to stand against 185-knot gales. The screens-four at Thule, three at Clear-will detect Communist missiles along a direct line of sight tangential to the earth after the missiles have been airborne for five minutes of their 30-or-so-minute nights toward U.S. targets. Then smaller radars inside mammoth 150-ft. domes-three at Thule, two at Clear-will track the incoming missiles...
...polar orbit. But it had not been spotted visually, perhaps because its orbit carried it over the world's inhabited areas in bright daylight or darkness, when it is hard to see. The nine-station radio fence that spans the U.S. and is supposed to detect any silent satellite had reported no sign...
