Japan and South Korea will conduct their joint radioactivity survey near the disputed islets in the Sea of Japan from Oct. 7 to 14, Foreign Ministry officials said Saturday.

The two nations reached the agreement on the schedule at a two-day working-level meeting through Saturday in Tokyo.

Each country will dispatch one vessel, and three research staff from each country will be aboard the other ship.

The two sides will exchange data and seawater samples.

The survey will cover six locations, including disputed waters around the South Korean-administered islets also claimed by Japan.

The survey is designed to examine the effects of contamination from radioactive waste dumped by the former Soviet Union.

Of the six locations, three are in waters near the islets -- known as Takeshima in Japan and Dokdo in South Korea -- where the Japan-claimed exclusive economic zone overlaps that of South Korea's EEZ.

Tokyo proposed the joint survey after South Korea protested Japan's plan to conduct the survey on its own.
