...adversary. A witness for the prosecution will be an atomic scientist, armed with "radiation fingerprints," evidence that can be as accurate and reliable as a photograph of the actual crime. No ordinary cop could hope to gather such fingerprints, or even to decipher them. They are the product of neutron activation analysis, which requires that specimens under study be irradiated with neutrons in a nuclear reactor. Then the fine details of their chemical composition can be deduced from the pattern of the radiation they give...
...Neutron activation analysis functions best as a reverse application of the common fingerprint technique-instead of gathering evidence a criminal leaves at the scene of his crime, it permits examination of evidence that the scene (or the weapon) leaves on the criminal. It can serve as an omniscient monitor of the most carefully planned alibis...
Send on Signal. Other instruments mounted on the drum record radiation from both sun and sky as the drum spins, and a neutron counter catches neutrons bounced up from the earth's atmosphere by the impact of cosmic rays. All the readings are recorded on tape during each orbit. When OSO passes over a Minitrack radio station, it is given a signal that makes the tape reverse its motion and quickly send its data down to earth...
...Isaac Newton's head and inspired his theory of gravity. In its famed Cavendish Laboratory, founded in 1872, Cambridge boasts one of the world's great centers of nuclear research. At Cavendish in 1919, Sir Ernest Rutherford first demonstrated nuclear reaction. Then Sir James Chadwick discovered the neutron; others have gone on to everything from the kinetic theory of gases to isolating the insulin molecule and piercing space with radio astronomy. "When it comes to research," says one Cavendish man. "we knock Oxford...
...Atomic Energy-called last week in strong words for atmospheric tests. Said Anderson: "We must conduct atmospheric tests because the underground tests have not given us all the answers we need." Connecticut's Democrat Senator Thomas J. Dodd demanded a crash program of testing to develop a deadly neutron bomb (TIME, July 7), which scientists still consider several years away from reality. Added Georgia's Democratic Senator Richard B. Russell: It is essential to ''conduct some atmospheric tests-until we perfect the neutron bomb...
