...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...
...completely buried implant, used by Dr. Stanley Behrman of Cornell University Medical College. The Behrman method, aided by modern physics, uses tiny (onequarter inch long) cobalt-platinum alloy magnets, the most powerful of their size ever developed. Inserted into the upper or lower jaw, the magnets attract other small magnets placed in the overlying denture to keep them in place. The mesh-covered magnets are strong enough to last the life of the denture-user...
...America. The total is still small, but a few big contracts are beginning to roll in. Last week Freeport Sulphur Co. ordered about $500,000 worth of titanium tubing from Titanium Metals Corp. of America to carry a highly corrosive ore slurry at Freeport's new nickel and cobalt mine in Cuba...
...small powers-Albania and Egypt -started the last of all wars, but the big powers finished it. A-bombs H-bombs, massive cobalt bombs obliterated the industrial cities of East and West. The winds carried radioactive dust to hamlet and farm, from Scandinavian fiord to Pacific island. A vast silence fell over the Northern Hemisphere. And now the dust is coming south, covering the earth as uniformly as a bandage wrapped with slow deliberation around an orange. Scientists estimate that it will take about nine months to envelop the Southern Hemisphere from the equator to the pole. Then the earth...

Mondrian, too, was a painter of the Dutch farm countryside, who gradually increased the intensity of his colors until they glowed with slashes of crimson, cobalt blues and rich mauves...
