Soviet gymnast Olga Korbut visited the Fred Hutchinson Cancer Research Center with her family for tests to determine if they are among the victims of the 1986 nuclear explosion in Chernobyl.

Korbut, who won three gold medals at the 1972 Olympic Games in Munich, lived in Minsk, about 180 miles from Chernobyl, when the explosion occured.She now suffers from fatigue and thyroid problems like others exposed to the radiation, she said in an interview after arriving Tuesday for a two-day visit.

Speaking through an interpreter, Korbut said she would unveil the Olga Korbut Foundation during her stay. The foundation is to help victims of radiation in Byelorussia, the Soviet republic in which Chernobyl is located.

"I have a great desire to benefit the people of Byelorussia," she said. "All the people are so depressed. There are no acute problems. . . . But they get tired very fast."
