SEOUL, April 16 (UPI) -- The Korea Institute of Nuclear Safety says traces of radioactive material from Japan's stricken nuclear power plant have been detected in South Korea.
The agency confirmed in a Yonhap news agency report Saturday South Korea's 12 detection centers have identified traces of iodine-131, cesium-137 and cesium-134.
However, it said the materials are not dangerous to people or the environment at current levels.
Seoul first confirmed the existence of radioactive particles in the air on March 28, 17 days after the Fukushima nuclear power plant was damaged by a tsunami that followed the March 11 magnitude-9 earthquake that struck Japan.
The highest cesium readings were taken from samples collected at the port city of Gunsan, about 200 miles southwest of Seoul, with the highest iodine readings coming from Gangneung on the east coast.
