Show TtiiTM-- n 'Fingerprints' Placed - product consists of microscopic d particles that can be incorporated into almost any solid or semi-solimatter and provide identification similar to fingerprints. The tags about the size of a grain of salt can be used to mark migratory animals, identify private property and disclose the amount of medicine in livestock, but probably their most important use involves the identification of dynamite. The Treasury Department's Bureau of Alcohol, Firearms and Tobacco is testing the product. Roy Parker, manager of the testing project with the AFT in Washington, said the tags will provide "very important leads to bomb investigators." The tags could lead to more convictions and fewer terrorist bombings, Parker said. Five bills are pending in Congress to make manufacturers add microtaggants to explosives and file their identifying tags with the AFT. In a recent AFT test, an auto was' loaded with explosives and detonated, destroying the car. The federal agents magnetically swept the area and found the microtaggants. A closer look "under a microscope revealed a sequence of colors on each layer of the tags. The color code then revealed the type explosive used, where it was manufactured, when it was made and who distributed it. The distributor could possibly lead police to the actual buyer of the explosives. Since each tag has nine layers, each one a different color, there are several million different color codes available. multi-layere- d - By CARL A. VINES water, is boosted to fusion temperatures.

"It has the same information on it the label on dynamite now has, but the label is blown off after the explosion "With this, a few minutes after the explosion, investigators would have a lead as to where the dynamite came from ... while the trail is still hot." A simple pocket microscope can detect the tags, yet there would be so many of them in one stick of dynamite it would be nearly impossible for someone to pick all of them out Microtaggants can be bought by consumers, who can mix them with paint and lacquer to cover private property Ultraviolet light will reveal the color code on the tags under the paint if the property is ever stolen "People can buy the tags and have their own code," O'Brien said.

Scientists doubt that small amounts of the spilled Promethium can penetrate a soldier's hands. But there is concern that the radioactivity may be ingested by troops eating with contaminated fingers. Also, observers worry that discarded gunsights could be found and taken home by curious civilians. In all likelihood, the radioactive sights have already found their way into at least some homes. A sergeant at Fort Riley says he knows of a case where a soldier mailed a leaking gunsight to his younger brother. The sergeant says the vials make "pretty good Army souvenirs."

THK HKHALD. 12 Gunsight Sparks Controversy and Fear Proton Gun Is Key To Fusion Research OAK RIDGE, Tenn. (UPI) -Researchers at Princeton University have moved the nation another step toward harnassing nuclear fusion for energy production thanks to a device the neutral designed and built here beam injector. Using three of these proton guns shipped from Oak Ridge, Princeton physicists proved that hydrogen gas device and contained in a donut-shape-d confined within a powerful magnetic field can be raised to 60 million degrees Fahrenheit without the whole thing running out of control. Researchers expect that by adding a fourth neutral beam injector they can achieve temperatures in the fusion range, around 80 million degrees. The recent Princeton success was a significant advance in research in nuclear fusion, the process by which two atoms are welded together to release energy. And it moves the nation closer to the eventual commercial use of fusion as a power source in the 21st century. Useful fusion can be achieved only when three things occur. First, hydrogen gas, or some isotope of hydrogen such as tritium and deuterium found in abundance in sea i Radioactive Promethium 147 On Explosives Could Help Fight Terrorism CHICAGO (UPIi A new product being tested by federal authorities will help police trace explosives that have already been detonated to the distributor and possibly even the buver. thereby curbing terrorism.
