Detailed Analysis Results in the Port of Fukushima Daiichi NPS, around Discharge Channel and Bank Protection, Jan.30, 2014:

“The highest dose among the results previously announced in the ‘Detailed Analysis Results in the Port of Fukushima Daiichi NPS, around Discharge Channel and Bank Protection’”

Wall St. Journal, Jan. 31, 2014: Among the radioactive materials that were dispersed at the site, the potentially lethal alkaline earth metal [strontium] poses the biggest immediate concern, because, unlike cesium, it doesn’t get trapped in soil and tends to accumulate in bones of fish and animals if ingested. [...] strontium has been slowly moving to deeper into ground water, which could be moving toward the ocean. [...] Radiation levels in groundwater sampled from several monitoring wells have been very slowly rising since last summer and radioactive strontium has been detected since October, according to data from Tokyo Electric Power Co., which operates the Fukushima Daiichi plant.

The Asahi Shimbun, Jan. 31, 2014: A team of reporters from The Asahi Shimbun visited the site on Jan. 29. [...] Another problem exists underneath the embankment on the eastern side of the plant site. Radioactive materials have been found to be spreading under that embankment. [...]
