As Japanese workers pumped out contaminated water into the Pacific Ocean from the quake-hit Fukushima nuclear facility, authorities on Tuesday said radioactive iodine several million times the legal limit was detected in seawater near the plant but insisted that it posed no major health risk. The plant's operator, Tokyo Electric Power Company (TEPCO), which last week said that contaminated water was leaking from a cracked concrete pit near the No. 2 reactor, found that radiation level in seawater samples was 7.5 million times the maximum allowable limit. The utility firm said the samples taken near the water intake of the No. 2 reactor on Saturday last contained 300,000 becquerels of iodine 131 per cubic cm, or 7.5 million times the legal limit. It said the figure had dropped to 200,000 becquerels per cubic cm, or five million times the legal limit, in samples taken on Monday, national broadcaster NHK reported. The samples taken on Monday also contained 1.1 million times the legal limit of cesium 137, more than three weeks after the mon ster magnitude-9 quake and tsunami hit Japan
