MOSCOW (AP) – A Russian researcher said Friday he has been charged by security agencies for allegedly selling state secrets, making him the latest scientist arrested by law enforcement authorities on those charges.

Prosecutors also charged Oscar Kaibyshev, 66, with illegally exporting dual-use technologies, or techniques, machinery, equipment or software that can be used both for civilian and military purposes, said Yuri Gervis, the scientist’s lawyer. That charge involves a Korean company, Kaibyshev said.

Kaibyshev could be sentenced to at least 10 years in prison if convicted of the most serious charges, Gervis said.

Kaibyshev said he has been prohibited from traveling outside his home city of Ufa, about 750 miles east of Moscow, since last month and was suspended from his post as director of the Institute for Metal Superplasticity Problems.

A growing number of academics have been targeted by the Federal Security Service, the main successor agency to the KGB, for alleged espionage or misuse of classified information.

Human rights advocates have said the security agency is deeply suspicious of Russian scientists’ contacts with foreigners, and it has been emboldened by the rise of former director Vladimir Putin to the presidency.

Gervis and Kaibyshev could not provide any more specific information on the state secrets charges.

Kaibyshev said the technology he has been charged with illegally exporting involves using molecular processes to shape metals without causing them to lose their strength. It can be used, for example, in manufacturing jet engines.

He said the criminal case specifically involved Korean company ASA, which approached him and his institute seeking to acquire the technology for use in making automobile tires. Officials at ASA in South Korea declined to comment.

The technology has been patented in the United States and other countries, Kaibyshev said, and articles about it have been published in several countries.

“Every piece of information that we have indicates that he has operated his institute within the laws of the Russian Federation,” said John Shideler, president of Virginia-based Futurepast Inc., which next month will publish a book co-authored by Kaibyshev describing some of the technology.

The book’s publication is being funded by the International Science and Technology Center in Moscow, a program launched by the State Department to help Soviet military scientists turn their research to civilian uses.

Kaibyshev said he has been interrogated several times by Federal Security Service agents, most recently Thursday for some six hours, and he said his bank accounts have been frozen.

An official at the regional bureau of the Federal Security Service refused to comment. No one answered the phone at the regional prosecutors’ press office Friday.

Last year, arms control researcher Igor Sutyagin was convicted of treason for allegedly selling information on nuclear submarines and missile-warning systems to a British company that Russian investigators claimed was a CIA cover.

Also, physicist Valentin Danilov was found guilty of selling classified information on space technology to China.
