Japan: Level of iodine-131 in seawater off chart

The Japan Times - The level of radioactive iodine detected in seawater near the Fukushima No. 1 nuclear power plant was 1,250 times above the maximum level allowable, the Nuclear and Industrial Safety Agency said Saturday, suggesting contamination from the reactors is spreading.

Meanwhile, plant operator Tokyo Electric Power Co. turned on the lights in the control room of the No. 2 reactor the same day, and was analyzing and trying to remove pools of water containing radioactive materials in the turbine buildings of reactors 1 to 3.

The iodine-131 in the seawater was detected at 8:30 a.m. Friday, about 330 meters south of the plant's drain outlets. Previously, the highest amount recorded was about 100 times above the permitted level. Read more.
