IAEA: Japan detects radioactivity 30 km off coast

Japanese scientists have found "measurable" concentrations of radioactive iodine-131 and caesium-137 in seawater samples taken 30 km (18.6 miles) from land, the UN nuclear watchdog said on Thursday.

"The iodine concentrations were at or above Japanese regulatory limits, and the cesium levels were well below those limits," the International Atomic Energy Agency (IAEA) said. (Reuters)
