Next month a U.S. team will similarly monitor a Soviet nuclear test at Semipalatinsk, U.S.S.R. The idea: to make sure that both sides can verify whether a test yields more or less than 150 kilotons. If the joint- verification experiment is successful, the U.S. and the Soviet Union could at last ratify two treaties that ban more powerful tests, and the world might be a tiny bit safer...
Assorted tools, wire, rocks and dirt are not the stuff that spooks seek in spy novels. But such materials turned up last month when Soviet inspectors searched personal items being shipped home by three Americans working for the Energy Department at the Semipalatinsk nuclear test site. Soviet authorities charged that the items were sensitive and that shipment of them was banned under the agreement permitting each superpower to monitor underground tests on the other's territory...
...unprecedented arrangement will allow U.S. seismologists to place three monitoring stations within 100 miles of Semipalatinsk, 1,800 miles from Moscow in eastern Kazakhstan, and Soviet scientists to erect their sensors near Yucca Flats, Nev., where U.S. universities have monitored underground tests for years. (Atmospheric tests were halted in 1963 after the U.S. and the Soviet Union signed the Limited Test Ban Treaty.) The U.S. team, led by University of Colorado Seismologist Charles Archambeau, will place digital seismometers in three 300-ft.-deep holes drilled by the Soviets. A two-man team will remain near Semipalatinsk to monitor the findings...
