Contaminated water from Japan’s crippled Fukushima nuclear power plant is seeping into the sea, according to the operators. The 8in (20cm) crack in a containment vessel at reactor two could be the source of current radiation in sea water, officials of Tokyo Electric Power said. Readings taken on Saturday indicated that radiation has spread to 40 km (25 miles) in coastal waters south of the nuclear plant. The iodine concentration there was double the legal level, but officials asserted that it was still lower than levels considered harmful to human health.
