New expedition to study Fukushima accident aftermath to leave Vladivostok

The second expedition of the Russian Geographical Society to study the aftermath of the accident at Fukushima-1 nuclear power plant is leaving Vladivostok on August 17.

"The expedition will leave port Vladivostok on the scientific ship Akademik Shokalsky. The voyage is expected to last until September 14," deputy director of the Far Eastern Regional Research Institute of Hydrometeorology Yevgeny Karasyov told Interfax on Monday. Akademik Shokalsky will cross the Sea of Japan, enter the Pacific Ocean through Sangar Strait, proceed along the Kuril-Kamchatka range and return to the Sea of Japan though La Perouse Strait ending up in Vladivostok.

Scientists will measure the power of gamma radiation above the sea surface, sample water on the surface and at greater depths. The water will be studied for the content of radioactive cesium, strontium 90, isotopes of plutonium and tritium. The scientists will also conduct round-the-clock monitoring of the content of radionuclide in the air.

The Russian Geographical Society organized its first expedition to study the radiation situation in the Far East following the Fukushima tragedy in spring 2011. On the scientific ship Pavel Gordiyenko scientists sampled the water, air and fish in different parts of the Sea of Japan. They did not discover any radiation hazard to the population of the Russian Far East.
