A member of Andrei Sakharov's family said the Soviets apparently have released more misleading "KGB home movies" showing the dissident in good health to counter conflicting statements Sakharov's wife, Yelena Bonner, might make in the United States.

"They're trying to soften the impact on public opinion of the hunger strike he held for six months," said Efrem Yankelevich, Bonner's son-in-law, of Sakharov's fast to help his wife win permission to seek medical treatment in the West.

Yankelevich said the family has booked a call to Sakharov for Thursday, four days earlier than planned. Bonner, meanwhile, met with a cardiologist at Massachusetts General Hospital. A hospital spokesman said she would undergo tests this week and the doctor, Adolph M. Hutter, would decide Friday what course to take.

The film, obtained by the West German newspaper Bild, apparently was made with a hidden camera and shows Sakharov in good health. Bonner told Yuri Tuvim, a family friend here, that she was unaware that she and Sakharov were being filmed.

"Sakharov goes shopping in Gorky, rides in a taxi, lugs shopping bags and heavy suitcases, calls on the telephone and discusses the arms race, 'Star Wars' and the Reagan-Gorbachev meeting in Geneva," Bild said in summarizing the tape.
