Seawater off Fukushima has record high radiation

Record high radiation in seawater off Fukushima plant, Japan Times, 17 May 14 Radiation has spiked to all-time highs at five monitoring points in waters adjacent to the crippled Fukushima No. 1 power station, plant operator Tokyo Electric Power Co. said Friday.

The measurements follow similar highs detected in groundwater at the plant. Officials of Tepco, as the utility is known, said the cause of the seawater spike is unknown.

Three of the monitoring sites are inside the wrecked plant’s adjacent port, which ships once used to supply it.

At one sampling point in the port, between the water intakes for the No. 2 and No. 3 reactors, 1,900 becquerels per liter of tritium was detected Monday, up from a previous high of 1,400 becquerels measured on April 14, Tepco said.

Nearby, also within the port, tritium levels were found to have spiked to 1,400 becquerels, from a previous high of 1,200 becquerels.

And at a point between the water intakes for the No. 1 and No. 2 reactors, seawater sampled Thursday was found to contain 840 becquerels of strontium-90, which causes bone cancer, and other beta ray-emitting isotopes, up from a previous record of 540 becquerels.

At two monitoring sites outside the port, seawater was found Monday to contain 8.7 becquerels and 4.3 becquerels of tritium. The second site was about 3 km away……… http://www.japantimes.co.jp/news/2014/05/17/national/record-high-radiation-in-seawater-off-fukushima-plant/#.U3ptgdJdWik
