Levels Recorded Haven’t Been Seen Since Soon After 2011 Disaster

Extremely high concentrations of radiation have been detected in water from near one of the reactors at the Fukushima Daiichi nuclear plant, [Tepco] said Saturday. [...]

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. [...] In April 2011 a combined 1.8 billion becquerels was recorded. [...]

The sample came from a trench near the No. 2 reactor turbine building, the utility said. [...]

Tepco is searching for the water source. It is probably from one of the damaged reactor cores. It is trying to stop the water leaking into the sea, it said. [...]

Asahi Shimbun: A liter of the water was also found to contain 750 million becquerels of radioactive substances that emit beta rays, such as strontium.

EXSKF: 5,000 cubic meters, or 5,000 tonnes of this water is in the trench.

Note: 5,000 cubic meters of water is equal to 5 million liters. One liter was found to contain 2.35 billion becquerels of cesium. If this concentration is consistent, the total amount would be nearly 12 quadrillion becquerels of cesium in this one trench.
