11th January 2014 – Fish with very high levels of cesium found near Fukushima.
The Fisheries Research Agency said Jan. 10 the black sea bream had 12,400 becquerels per kilogram of radioactive cesium, 124 times the safety standards for foodstuffs.
The fish was caught at the mouth of the Niidagawa river in Iwaki.
9th January 2013 – TEPCO withheld Fukushima radioactive water measurements for 6 months
Tokyo Electric Power Co. has withheld 140 measurements of radioactive strontium levels taken in groundwater and the port of the Fukushima No. 1 nuclear plant between June and November last year.
25th December 2013 – ‘Fukushima fish ends in garbage’: Radioactive fears blight Japan’s seafood industry
There is significant contamination in the bottom segment, especially in the pond and the river system, where we can find a very high amount of radioactive cesium accumulated.
Most of the fish caught within the 30 kilometer radius is thrown into the garbage because it is radiated. And TEPCO is paying to local fishermen for it, so that they’re happy and keep silent on that. Some of it though makes it to stores, but only locally.
23 December 2013 – 1,900,000,000 Bq/m3 of all β nuclide in groundwater on seaside of reactor2 / Keeps increasing for a month.
19th December 2013 – Iodine-131 rises in Chiba prefecture.
The most recent measurements of iodine-131 in sewage sludge from Chiba prefecture indicate the highest amount of I-131 since August. The last measurement was actually made on Dec. 3. It is the third highest measurement since May 2011.
9th March 2012 – Asahi: Iodine-132 not considered in tests showing high thyroid radiation levels in Fukushima residents — Dose could be much greater.
“Levels could have exceeded 100 millisieverts if infants had stayed in a district with a high iodine concentration,” said professor Shinji Tokonami, who led the research team. “The central and local governments need to provide thorough care to protect the health of children.”
“The research is valuable because it is based on measurement data more detailed than the government’s, although iodine 132, whose half-life is two hours, is not considered,” said Yoshio Hosoi, a professor at Hiroshima University’s Research Institute for Radiation Biology and Medicine.

17th November 2011 – Absorbed radiation dose of iodine-132 was 10 times higher than iodine-131 in Northern Japan after Fukushima meltdowns — Plus iodine-132 is 9 times more ‘effective’ at irradiating thyroid
19th December 2013 – 434,000 Bq/Kg of Cs-134/137 from Shimeji mushroom in Minamisoma city / 4,340 times much as “safety limit.”
18th December 2013 – 1,070 Bq/Kg of Cesium-134/137 detected from fish 2km offshore of Fukushima Daini / Over 10 times much as safety limit.
18th December 2013 – Inside Japan’s battle to prove fish is safe after Fukushima nuclear disaster
MERI screens 200 species every year, including shellfish and seaweed, as well as the more common cod and salmon, from waters as deep as 1,300 feet. Seawater and sediment are also monitored, as are freshwater fish.
A reading of more than 100 bequerels per kilogram triggers an automatic ban. By comparison, the U.S. tolerates much higher amounts of radiation; 1,200 bequerels per kilogram.
Amassing the results of tens of thousands of samples like this, Japan’s Fisheries Agency says ocean and fish contamination has sharply declined since the March 2011 nuclear accident at the Fukushima Daiichi nuclear plant. In the three months following the catastrophe, 53 percent of fish sampled off Fukushima showed radiation levels surpassing the safety limit of 100 bequerels per kilogram. By the following year, the proportion of contaminated fish had halved.
The latest research I have seen suggests 5 Bq per Kg of Cesium or less for children and preferably none. If this is the case, then both the Japanese and USA standards are set way to high.
It is not just Cesium and Strontium contamination that should be reported. There are lots of other Isotopes that can be potentially bio-accumulating in this sea food that they don’t talk about.
16th December 2013 – Radioactive cesium levels in Miyagi forest soil up since 2011
In a forest in the town of Marumori closer to Fukushima, the average cesium level of 10 samples of fallen quills was 26,684 becquerels per kilogram in June 2012, but rose to 42,759 becquerels a year later. And the level in soil up to 10 cm deep increased from 721 becquerels to 3,225 becquerels, according to the study.
16th December 2013 – What the Japanese Government Isn’t Saying About Fukushima
The Japanese parliament has just passed the state secrets law. It’s really an information ‘iron curtain’ that’s preventing people in Japan from learning just how bad the exposures were that they received after the accident at Fukushima.
16th December 2013 – Damage from Fukushima is unprecedented, a disaster never before experienced in human history
