The operation will be conducted in the Kara Sea on August 27-September 20 as part of an Emergency Situations Ministry effort on the government's instructions to draw up a list of potentially dangerous submerged objects.
"We will examine the condition of potentially dangerous objects under water at the given section, decide how dangerous they are, and assess the pollution of the sea water and the seabed soil," a spokesman for the ministry said.
He said experts would use a mobile radiation control complex, and a monitor-controlled submerged apparatus.
An expedition in two other sections of the Kara Sea last year studied containers with hard radioactive waste from a K-27 submarine buried on the seabed and the possible burial site of a nuclear reactor of a K-254 (Victor III class) submarine.
"The results showed that the radiation environment in these sections was stable and hulls of the objects lying on the Kara seabed were intact," the spokesman said.
