EXSKF, Feb. 13, 2014: […] four small pieces of debris found at the river mouth in Naraha-machi 15 kilometers from the plant may have come from Reactor 3. […] TEPCO disclosed the result of the analysis of the debris done by Japan Atomic Energy Agency […] TEPCO and JAEA’s conclusion [is that] small pieces of debris came from Fukushima I Nuclear Power Plant, most likely from the Reactor 3 building […] There will be no further analysis whether there is any contribution from MOX fuel […]
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.
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.
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”.
A professional video of Marco Kaltofen’s presentation to the American Public Health Association was recently made available to Fairewinds. Kaltofen states that hot particles are contaminating portions of northern Japan. He also states that auto air filters from Fukushima, that he tested in his Massachusetts laboratory, are so radioactive that they have to be disposed of in a buried radioactive waste disposal site in the US. Additionally, he expresses concerns for the mechanics who work on cars in Fukushima Prefecture. Continue reading »
The disastrous effects of the Fukushima Daiichi nuclear catastrophe are still emerging nearly a year after the fact, as a popular Japanese baby formula company has now announced a massive recall of baby food tainted with radiation. Meiji Holdings Co., maker of Meiji Step infant powder (Meiji Step is only sold in Japan) is recalling 400,000 cans of the product because of contamination with radioactive cesium.
ABIKO, Chiba — High levels of radiation have been detected on the premises of two elementary schools here, local education authorities have revealed.
According to the Abiko Municipal Board of Education, 11.3 microsieverts of radiation per hour was detected just above the surface of the ground near a ditch in the compounds of the Abiko Municipal Daiichi Elementary School on Sept. 15. The amount was 1.7 microsieverts in the air 50 centimeters above the ground.
Soil had piled up in the ditch, which had been damaged by growing tree roots, a situation similar to a residential area of the Chiba Prefecture city of Kashiwa where 57.5 microsieverts per hour was detected.
Radioactive cesium amounting to 60,768 becquerels per 1 kilogram of soil was found in the ditch.
The highly radioactive dirt in Kashiwa City in Chiba, which measured 57.5 microsieverts/hr 30 centimeters below the surface, was not from radium after all or any other nuclides that are used in industrial or medical use (some suggested cobalt-60, for example). It was from radioactive cesium.
On October 22 Kashiwa City announced the result of the analysis of three dirt samples from the location at different depth (one on the surface, two at 30 centimeter deep). The analysis was done on October 22. The unit is becquerels per kilogram:
550 to 690 becquerels/kg of radioactive cesium detected in the commercial teas grown in 3 tea plantations in Tokyo. The Tokyo Metropolitan government tested 30 teas in early October, and radioactive cesium was detected from 29 of them.
Tokyo Municipal government announced on October 18 that 550 to 690 becquerels/kg of radioactive cesium, exceeding the national provisional safety limit of 500 becquerels/kg, was detected from the “Tokyo Sayama-cha” tea from three tea plantations in Tokyo. It is the first time radioactive cesium was detected from commercial teas grown in Tokyo.
Chris Busby updates Japan on what to do to reduce the risk of radiation damage from the contamination from the Strontium-90, Uranium and Plutonium dispersed widely over northern Japan.
First of all, evacuate the children and evacuate yourselves. The contamination of the ground and the food is a serious health hazard. Car air filter analysis shows the material on the ground becomes airborne and can be inhaled.
Get away If you can; but if not not then you can reduce the access of these radionuclides to the DNA. It is basic Physical Chemistry that increasing the Calcium concentration, (Calcium which stabilises the DNA phosphate backbone), will inhibit the equilibrium binding of radionuclides like Strontium, Uranium, Plutonium and other high DNAP affinity elements and complex ions.
And it is higher, much higher than the Ministry of Education’s aerial survey indicates.
First, to recap, according to the just released Ministry of Education’s aerial survey of radioactive cesium deposition in Tokyo, most of Tokyo has less than 10,000 becquerels/square meter of radioactive cesium, with the exception of the western-most Okutama and the eastern special wards (“ku”) bordering Chiba Prefecture to the east.
Now, it turns out that the Tokyo Metropolitan government, who is not so eager to measure anything radioactive since March 11, was doing its annual survey of soil contamination in Shinjuku and quietly released the data on September 20.
The soil sample was taken at Tokyo Metropolitan Institute of Public Health in Hyakunin-cho, Shinjuku-ku, as it has always been done. (That’s where the official air radiation level is monitored every day for Tokyo.)
For the last 5 years, radioactive iodine and cesium-134 were not detected, and cesium-137 was 2 to 3 becquerels per kilogram.
Now, this year, the numbers for the soil from the surface to 5 centimeters deep were:
Cesium-134: 360 becquerels/kg
Cesium-137: 430 becquerels/kg
Total cesium: 790 becquerels/kg
To convert from “per kilogram” to “per square meter”, Japan’s Nuclear Safety Commission uses the factor of 65. The total cesium per square meter in Shinjuku therefore is: 51,350 becquerels per square meter.
Even if you just take cesium-137 (for comparison purpose), 430 becquerels/kg translates to 27,950 becquerels/square meter.
NGO “FoE Japan (Friends of Earth Japan) did its own survey of radiation contamination in Watari District in Fukushima City with the help from Professor Tomoya Yamauchi of Kobe University. Watari District has high radiation levels throughout the district, but the national government has so far refused to designate anywhere in the district as “evacuation recommended” area.
If the government designate an area as such, the government has to pay for the relocation cost. As the result, the designation in other cities like Date City has been very arbitrary and spotty, rendering the whole exercise worthless. Often, the residents are simply moved to the other parts of the same city with slightly lower radiation.
“Japan has no centralized system to check for radiation contamination of food, leaving local authorities and farmers conducting voluntary tests. Products including spinach, mushrooms, bamboo shoots, tea, milk, plums and fish have been found contaminated with cesium and iodine as far as 360 kilometers from Dai-Ichi.
Hay contaminated with as much as 690,000 becquerels a kilogram, compared with a government safety standard of 300 becquerels, has been fed to cattle. “
Radiation fallout from the wrecked Fukushima nuclear plant poses a growing threat to Japan’s food chain as unsafe levels of cesium found in beef on supermarket shelves were also detected in more vegetables and the ocean.
More than 2,600 cattle have been contaminated, Kyodo News reported July 23, after the Miyagi local government said 1,183 cattle at 58 farms were fed hay containing radioactive cesium before being shipped to meat markets.
That’s an amazing reduction from the maximum emission of 2,000 terabecquerels per hour on March 15, it is actually one-2 millionth of the maximum, says TEPCO in the Reference No. 2 of the progress report on the “roadmap” to God knows where.
Is this number, 1 billion becquerels per hour emission, good? TEPCO’s Matsumoto, in the press conference on July 19, avoided the judgment, and said he didn’t know, but it was one-2 millionth of what it had been on March 15.
On closer reading of the document, though, I noticed one strange thing about this emission number. TEPCO is talking about the radiation emission measured in cesium (cesium-134 and -137), not in iodine equivalence.
To come up with the iodine-131 equivalence, you have to multiply cesium-134 by 3, and cesium-137 by 40 (according to INES handbook). TEPCO doesn’t even give the breakdown of cesium 134 and -137 in its calculation of 1 billion becquerels/hour number. Other nuclides have even higher multiplier: americium-241 is 8,000, plutonium-239 is 10,000.
If half of 1 billion becquerels is cesium-134 and the other half is cesium-137, then in iodine-131 equivalence like in the previous calculations, the emission would be:
(0.5*3)+(0.5*40)=1.5+20=21.5 billion becquerels/hour Instead of 1 billion becquerels/hour, it would be 21.4 billion becquerels/hour in iodine equivalence, or 516 billion becquerels in one day. In less than 2 days, we would be talking about over 1 terabecquerels.
Children from 3 public elementary schools in Itabashi-ku in Tokyo did the tea picking in early May, the tea leaves were roasted and made into the final blend tea and was about to be given to the children. For some reason, the municipal officials decided to test the tea, and found radioactive cesium to the tune of 2,700 becquerels/kilogram, more than 5 times the loose national provisional safety limit of 500 becquerels/kilogram.
The public elementary schools and junior high schools in Itabashi are run by the Itabashi Board of Education. There are 53 elementary schools in Itabashi.
Itabashi-ku (special ward) in Tokyo announced on June 30 that 2,700 becquerels/kilogram of radioactive cesium were detected in the final blend tea grown and processed in Itabashi, exceeding the national provisional safety limit of 500 becquerels/kilogram.
Trace amounts of radioactive substances have been found in urine samples taken from children from Fukushima city, raising concerns that residents have been exposed internally to radiation from the stricken nuclear power plant 37 miles (60km) away.
Tests were conducted in May on 10 children, aged between 6 and 16, by a Japanese civic group and Acro, a French body that measures radioactivity. All 10 tested positive for tiny amounts of caesium-134 and caesium-137.
Tokyo – A small amount of radioactive substances was found from urine samples of all of 10 children in Fukushima surveyed by a Japanese civic association and a French nongovernmental organization, the groups said Thursday.
David Boilley, president of the Acro radioactivity measuring body, told a news conference in Tokyo that the survey on 10 boys and girls aged between 6 and 16 in Fukushima city suggested there was a high possibility that children in and near the city had been exposed to radiation internally, Kyodo News reported.
The highest levels found by the survey were 1.13 becquerels of radioactive cesium-134 per 1 litre of urine from an 8-year-old girl, and 1.30 becquerels of cesium-137 in a 7-year-old boy, Kyodo said.
The city is located 60 kilometres north-west of the Fukushima Daiichi nuclear power station, which has been leaking radiaoactive material into the environment since it was hit by the March 11 earthquake and tsunami.
Though the horrendous tsunami that hit Japan on March 12, 2011 seems like old news in the midst of today’s headlines, the crippled nuclear power plants at Fukishima Daichi continue to spew radiation into water, air and soil, with no end in sight.
Even as thousands of Japanese workers struggle to contain the ongoing nuclear disaster, low levels of radiation from those power plants have been detected in foods in the United States. Milk, fruits and vegetables show trace amounts of radioactive isotopes from the Fukushima Daichi power plants, and the media appears to be paying scant attention, if any attention at all. It is as if the problem only involves Japan, not the vast Pacific Ocean, into which highly radioactive water has poured by the dozens of tons, and not into air currents and rainwater that carry radiation to U.S. soil and to the rest of the world. And while both Switzerland and Germany have come out against any further nuclear development, the U.S. the nuclear power industry continues as usual, with aging and crumbling power plants receiving extended operating licenses from the Nuclear Regulatory Commission, as though it can’t happen here. But it is happening here, on your dinner plate.
Part of the contaminated water treatment system being readied at Fukushima I Nuclear Power Plant is the cesium absorption tower using the technology of Kurion, a US start-up with very little information on their corporate website.
TEPCO discovered that not enough water was flowing through one of the 4 subsystems, and suspects it’s clogged up somewhere.
And a bit of new information that the Kurion’s system removes not just cesium but technetium and iodine, according to the press conference handout from TEPCO which is found below.
By the way, the number of pipe leaks in the Areva’s system was not “over 10”. Well, it was “over ten” for sure, but it was actually 48.
From Yomiuri Shinbun (11:45AM JST 6/12/2011; diagram of Kurion’s system added):
TOKYO — Radiation levels up to several hundred times normal have been detected on the Pacific seabed in a 300-kilometer-long area off the crippled Fukushima Daiichi nuclear power plant, the science ministry said Friday.
The ministry said high-level radioactive materials were detected on the seabed in a north-south stretch ranging from Kesennuma, Miyagi Prefecture, to Choshi, Chiba Prefecture, and warned the contamination could affect the safety of seafood. The science ministry said it detected iodine and cesium on the seabed at 12 spots 15- to 50-km from the coastline between May 9 and 14.
Radioactive materials in concentration that was up to several hundreds of times the normal level were detected from the soil on the ocean floor in the 300-kilometer strip along the coast from Kesennuma City in Miyagi Prefecture to Choshi City in Chiba Prefecture.
Oh what a surprise. Who could have known?
The Ministry of Education and Science, who did the survey, even goes to contradict the oft-repeated statement by the chief cabinet secretary and says “the marine products may be affected.”
Chief Cabinet Secretary Edano’s favorite refrain whenever a new leak was found at Fukushima I Nuke Plant was: “It will have no immediate effect” on health, on environment, on anything. (These days, he is busy trying to “qualify” his use of “immediate”. Quite funny if the situation is not this dire.)
No word on other nuclides like plutonium, uranium, and strontium.
I’m trying to locate the original survey data at the Ministry’s site.
The Ministry of Education and Science disclosed on May 27 that radioactive materials in concentration that was up to several hundreds of times the normal level were detected from the soil on the ocean floor in the 300-kilometer strip along the coast from Kesennuma City in Miyagi Prefecture to Choshi City in Chiba Prefecture. The Ministry says “the marine products may be affected”. It is now confirmed that the radioactive materials in the contaminated water released [both intentionally and unintentionally] from TEPCO’s Fukushima I Nuclear Power Plant into the ocean have spread far and wide.
The soil samples were taken from May 9 to May 14 at 12 locations about 15 to 50 kilometers off the coast. Radioactive materials were detected in all samples. The highest concentration of radioactive materials was detected from the sample taken from the ocean floor, 126 meters deep, 30 kilometers off the coast of Fukushima I Nuke Plant. Cesium-134 was 260 becquerels/kilogram, and cesium-137 was 320 becquerels/kilogram.
