Sakharov’s Wife to Leave Russia Later This Month : Bonner Will Leave Russia Later in Month

Yelena Bonner, wife of Soviet dissident Andrei D. Sakharov, said today in a telegram that she will leave her exile home in the closed city of Gorky late this month to go abroad for medical treatment.

Bonner, 62, confined to Gorky since May, 1984, on charges that she slandered the Soviet state, told the friend who received the message here that she will be out of the country for several months.

The friend, who received the telegram from Gorky, 250 miles east of Moscow, asked not to be identified. The message did not say where Bonner would go.

Treated in Italy

She was allowed to go to Italy in 1975, 1977 and 1979 for treatment of glaucoma, an eye ailment she has suffered for years which threatens her with blindness. Her vision problem stems in part from a shrapnel wound she suffered in World War II when she served as a front-line medic.

Bonner also has a heart condition.

“I have received permission to leave. I’ll be leaving at the end of November,” the telegram read. “I am making preparations for Andrei to spend the winter alone.”

The only other information in the message was a request that the recipient send the couple’s regards to friends.

Permission Reported

Soviet journalist Viktor Louis said earlier this week that Bonner had been granted permission to go to the country of her choice for medical treatment and that it was up to her when she left.

The Sakharovs’ Moscow friend thought Soviet officials probably allowed Bonner to send the telegram in order to reduce the commotion caused by rumors that her departure was imminent. Western reporters have been waiting at Sheremetyevo Airport in hopes of talking with Bonner before her departure.

The friend speculated that if Bonner plans such a long absence from Sakharov, who is 64 and has a heart condition, both must be in relatively good health.

Bonner’s plan to spend several months abroad also may indicate that she intends to go to the United States, where her adult children live.

Her daughter, Tatiana Yankelevich, who lives in Newton, Mass., said Thursday that attempts to reach her mother by telephone had failed and that she had received no information about when or where her mother would be going.
