...women and children all over the non-Communist world, including such outskirts as Chile, South Africa and Formosa. At Columbia's Lamont Geological Observatory, in a project financed by the U.S. Atomic Energy Commission, they go under the scrutiny of scientists who analyze the bones for strontium 90. Last week the project's three scientists, Drs. Walter R. Eckelmann, J. Laurence Kulp and Arthur R. Schulert, made their second annual report. The bones told a sobering story of increasing amounts of radioactive fallout from nuclear-weapons tests...
...commonest kind of radioisotope is any element (gold, cobalt, strontium) that has been placed inside a reactor long enough to become radioactive, i.e., to shoot off alpha, beta or gamma rays. Then, when these rays hit another object, their speed or intensity changes; by using Geiger counters and other devices to detect the rays, technicians can learn many filings' about the objects under bombardment. And when isotopes are added to liquids, their flow can easily be followed by Geiger counters...
...rubber that goes onto each strand of tire cord. Recently, Industrial Nucleonics Corp. of Columbus, Ohio, one of the top sellers of isotope measuring equipment (1956 sales: $5,000,000), developed a foolproof method. As the tire cord goes through the rubberizing machine, it passes between a capsule of strontium 90 and a radiation counter. If the thickness varies, the detector's reading changes, automatically sets off machinery to adjust the rubber flow. Today all the major rubber companies use these "AccuRay" gauges at a saving of $20 million annually. With similar apparatus rolling mills can control the thickness...
...years late, Christianity is becoming all the rage. Everybody is going to church, talking about God, and trying not to talk about Strontium 90. Kirkegaard is out in paperback, and Aristotle is out in left field. President Pusey has announced the importance of the Divinity School, while Billy Graham converts thousands in Madison Square Garden...
...little is known to support hard-and-fast judgments. Dr. Harold A. Thomas Jr., Harvard professor of civil and sanitary engineering, who has worked for eight years with the AEC on safe disposal of radioactive wastes, says the field is full of mysteries and surprises. "We are concerned about strontium 90," he says, "but there are many other [fallout] materials whose effects are almost totally unknown." He suggests being more careful...
