(Before It's News)

Following up this article..1,000,000Bq/m3 of all β nuclides detected in seawater of reactor3 screen/Highest ever, 14 times much as 1 week ago [URL]

On 7/15/2013, Tepco also measured the highest reading of Cesium-134/137 in seawater since July of 2012.

The sampling location was reactor3 screen (Inside of silt fence). Cs-134 density was 350,000 Bq/m3, Cs-137 density was 770,000 Bq/m3. It started increasing on 7/13/2013. Cs-134/137 density jumped up to be 13.3 times much within 2 days.

They detected the highest reading of all β nuclide and Cs-134/137 on the same day in the same location. It is assumed that these are from the same source but Tepco hasn’t announced contaminated groundwater is flowing to the sea.
