According to mid/long term roadmap of Tepco released on 12/27/2012, 10 million Bq of cesium-134/137 is still released from reactor 1, 2 and 3 every single hour.
This is measured at the top part of each reactor building. The amount is computed from the dust density of Cs-134/137, other nuclides are excluded.
Since this April, the releasing amount has been stably around 10 million Bq / hour. Continue reading »
Dr. Helen Caldicott: If Spent Fuel Pool No. 4 collapses I am evacuating my family from Boston.
Few people know that the Pacific Northwest got whacked hard by fallout from the Fukushima disaster with radiation rates hundreds of thousands of times higher than normal background radiation.
The damage from this is not something that the corporate media or the government is talking about. It mysteriously disappeared from the radar almost immediately.
Dr. Caldicott referred to this as a process of “cover-up and psychic numbing.” Looks like it may be working.
The Nuclear Regulatory Commission just approved two new nuclear power plants this week (4/2/12) in South Carolina in addition to the two approved earlier this year in Georgia.
Dr. Caldicott talks about the dangers and hidden costs of nuclear power then tells the awful truth in minute detail about the actual scale of the Fukushima disaster and compares it to the nuclear disasters of Chernobyl and Three Mile Island.
Recent studies estimated that a million people have died so far from Chernobyl.
Dr. Helen Caldicott is a physician, Nobel Peace Prize winner, noted author, anti-nuclear power advocate and has founded numerous national and international groups which oppose nuclear power & weapons, including Physicians for Social Responsibility.
Minami Soma City assemblyman Koichi Ooyama discloses the result of the test of the mysterious black dust found in locations in Minami Soma City, Fukushima Prefecture.
A blogger whom I featured before, “Night that never ends”, has been measuring radiation on the strange, black dust he finds in many locations in Minami Soma City, mostly on the road surface. His geiger counter (Inspector) measures all alpha, beta, gamma radiations and x-ray, and his measurement on the surface of this black dust was 295 microsieverts/hour.
Assemblyman Ooyama apparently sent the sample to Professor Tomoya Yamauchi of Kobe University. Professor Yamauchi did the test, and here’s the result, fromAssemblyman Ooyama’s blog:
Cs-134: 485,252 Bq/kg Cs-137: 604,360 Bq/kg
TOTAL: 1,089,612 Bq/Kg
Converting the total number to Bq/square meter,
1,089,612 × 65 = 70,824,780 Bq/m2
“Night that never ends” says in his blog this substance is very light-weight and blows off easily. He is finding it all over Minami Soma. He has asked the construction workers if it is from asphalt used in roads. The workers say no. To see the image of this black dust, go here.
So the sunflowers DID concentrate radioactive cesium in soil. It was not where the Japanese government wanted you to find.
According to one Iitate-mura villager, Mr. Itoh, who had his sunflowers tested, the radioactive cesium was IN THE ROOTS. He suspects that the government knew, and cherry-picked the data that seemingly supported the foregone conclusion that sunflowers do not work in decontaminating the soil.
Why? Because the government wants and needs to distribute big money to big businesses that closely work with the government in the “decontamination” bubble that they’ve created.
Sunflower roots: Cesium-134, 39,500 Bq/kg; cesium-137, 52,100 Bq/kg; total 91,600 Bq/kg. Since the roots were burned at low a temperature, the roots were reduced to only one-quarter in mass. 2,200 grams of the roots were burned, resulting in 460 grams of ashes.
Toshihiro Takatsuji, associate professor at Nagasaki University announced the result of his measurement of radioactive cesium in the air at an international symposium, and said a high level of cesium-134 (11,300 becquerels/kg) was detected from the dust collected in the filter paper in early April last year in Nagasaki City,1,000 kilometers away from Fukushima I Nuclear Power Plant.
So, clearly there was a good reason why IAEA went to measure the radiation levels in Nihonmatsu City, Fukushima Prefecture when they came in March 2011 right after the March 11 nuclear accident.
The Ministry of the Environment announced on January 19 that 43,780 becquerels/kg of radioactive cesium was detected from the ashes in a wood stove used in a personal residence in Nihonmatsu City, Fukushima Prefecture.
I forgot to update the news of 230-tonne leak at Fukushima I Nuke Plant but toward the end of TEPCO’s press conference on December 18, the initial result of the nuclide analysis came in, and the number was rather high.
Cesium-134:
The trench water: 4200 becquerels/cubic centimeter (or 4.2 million becquerels/liter)
The water dripping from electrical duct: 0.13 becquerels/cubic centimeter (or 130 becquerels/liter)
No news yet on other nuclides, though Asahi Shinbun says cesium-137 was 5400 becquerels/cubic centimeter. If that’s the case, the cesium total would be 9600 becquerels/cubic centimeter of 9.6 million becquerels/liter. It is not as radioactive as the untreated, contaminated water (which is about 100 times as radioactive than this trench water), but still high for a plant that has achieved a “cold shutdown”.
