Gov't clears West Sea of N. Korean uranium wastewater concerns

South Korea says no contamination has been detected in the West Sea from North Korea's Pyongsan uranium plant wastewater.

A two-week probe by agencies here including the Nuclear Safety Commission found no contamination at 10 sites along the West Sea and nearby rivers.

Uranium cesium and heavy metals remained consistent with past levels and radioactive cesium was not detected.

The government nonetheless will continue its monitoring at several key locations amid satellite analysis suggesting wastewater flow from North Korea into the West Sea.
