The World - News from Aug. 18, 1987

A Soviet official conceded it was theoretically possible that a Soviet underground nuclear test could have caused slightly higher radioactivity over Sweden, but he said it was highly unlikely. Yuri Izrael, head of the Soviet Meteorological Service, told a news conference in Moscow there was no proof linking an Aug. 2 underground test on Novaya Zemlya island to the “infinitesimally small� increase of radioactivity in Sweden’s atmosphere. The press conference was called to reiterate a Soviet denial of a U.S. charge that there was a treaty violation.
