The Wall Street Journal reported today:
Extremely high concentrations of radiation have been detected in water from near one of the reactors at the Fukushima Daiichi nuclear plant, Tokyo Electric Power Co. said Saturday.
The levels recorded haven’t been seen since soon after the March 2011 disaster, it added.
The radiation is millions of times higher than Japan’s acceptable limit under normal circumstances.
Radiation of 750 million becquerels a liter of cesium-134 and 1.6 billion becquerels a liter of cesium-137 was recorded, Tepco said. The normal limits for the two potentially harmful isotopes are 60 and 90 becquerels, respectively. In April 2011 a combined 1.8 billion becquerels was recorded.
This story is particularly worrisome considering the fact that the damaged reactors at Fukushima are still leaking water into the ocean:
Water with much lower radiation—around 9,000-18,000 becquerels a liter–has leaked into the sea from groundwater, Tepco said earlier this week after the Nuclear Regulation Authority said it suspected seepage.
