The highest reading of all β nuclides detected in seaside of reactor2 / 1,100,000,000 Bq/m3 Posted by Mochizuki on November 30th, 2013
All β density in seaside of reactor2 is in the increasing trend again / 1,300,000,000 Bq/m3 Posted by Mochizuki on December 5th, 2013
4 days after the previous highest reading was detected, higher density of all β nuclides (including Strontium-90) was detected in the same location. The reading was 1,300,000,000 Bq/m3 (↑ 18%). The sampling date was 12/2/2013. In the press conference of 12/4/2013, Tepco stated it’s from the past leakage of contaminated water. There is no additional leakage on-going underground.
Insight - Fukushima water tanks: leaky and built with illegal labor
(Reuters) - Storage tanks at the Fukushima nuclear plant like one that spilled almost 80,000 gallons of radioactive water this year were built in part by workers illegally hired in one of the poorest corners of Japan, say labor regulators and some of those involved in the work...
The Okinawa crew was recruited by Token Kogyo, an unregistered broker, and passed on to work at the Fukushima plant under the direction of Tec, a larger contractor which reported to construction firm Taisei Corp, records show. That practice of having workers hired by a broker but managed by another contractor is banned under Japanese law to protect workers from having their wages skimmed and to clarify who is responsible for their safety...
Tepco has promised to improve working conditions in an unprecedented nuclear decommissioning project expected to take more than 30 years. [ID:nL4N0J31FR] The company said last month it would more carefully monitor sub-contractors and double the pay for thousands of workers after a Reuters report found widespread abuses, including falsified employment records, skimmed wages and a lack of worker contracts...
Yosuke Minaguchi, a lawyer who has represented Fukushima workers, said problems in enforcing labor standards in the nuclear clean-up could threaten its completion. Weeks later, radiation at the ground near one of the tanks spiked to a level so high that it would have caused radiation sickness within an hour if a worker had been directly exposed. That spike, after an apparent leak of radioactive water, occurred in the same area where Uechi and the Okinawa crew had been working - an open space known as H3 on an elevated plain above Fukushima's four wrecked reactors...
In one example, Uechi said workers were rushed to apply caulking to seal the tanks even when it was raining and snowing. "It didn't make any sense, because the caulking wouldn't get to the metal. It would float out," Uechi said. Tepco said it could not confirm details reported by Uechi, but said workers should not have been working on sealing the tanks in the rain because it could have made the sealant in the tanks more prone to fail...
Japan enacts state secrets law late Friday night amid revolt — “It criminalizes investigative journalism” — Terrorism defined as “imposing one’s opinions on others”
Japan Times, Dec. 6, 2013: Following political turmoil that rocked the Diet over the past week, ruling block Upper House members finally enacted the contentious state secrets bill late Friday night. Earlier in the day, opposition parties intensified their protests in vain over a law that’s being criticizing for not creating an independent oversight body capable of preventing the government from hiding inconvenient information at its discretion...
GlobalPost, Dec. 6, 2013: Here are four disturbing ways the bill could be a democracy muzzler. It defines terrorism as imposing one’s opinions on others [...] According to Article 12, terrorism is partially defined as an activity that forces “political and other principles or opinions on the state or other people.” In other words, throw up a rowdy anti-government protest, and the judiciary can find a reason to lock you away. It criminalizes investigative journalism [...] Journalists can be prosecuted for “improperly accessing” classified documents or “conspiring” to leak them. Even asking an official to take a look at classified documents could constitute “conspiracy,” leading to up to five years in prison. “Instigating” the release of government secrets, meanwhile, carries up to 10 years in the dock. [...] Basically, anything can be a secret [...] administrators can make the opaque decisions to classify a document even if their work hardly relates to national security. That effectively allows them to hide any embarrassing piece of evidence, and then pursue the journalists and bloggers who make it public...
ISIS Report 05/06/12 Truth about Fukushima The release of radioactivity from Fukushima is at least as great as from Chernobyl, and a humanitarian disaster on the scale of Chernobyl needs to be averted by acknowledging the truth and taking responsibility for mitigating measures Dr. Mae-Wan Ho
It is important to note that all the exposure limits and projected exposure mentioned so far are for external sources. As the French expert body, Institut de Radioprotection et de Sûreté Nucléaire (IRSN) pointed out, they take no account of “exposure from other pathways such as immersion within the plume and inhalation of particles in the plume during the accident nor the doses already received or to be received from ingestion of contaminated foodstuffs. The total effective doses to be received (external + internal) could be much higher according to the type of deposit (dry or wet), diet and source of food.”
In addition, as Director of the Medical Institute of Environment at Gifu in Japan Matsui Eisuke pointed out , the government and its professional advisors in measuring exposure have relied mainly on g-rays that are easy to detect. But, in terms of internal radiation exposure, b and a- particles have a far more serious effect. “The government and TEPCO hardly measure such isotopes as b-emitting strontium-90 or a-emitting plutonium-239.”
Exposure due to ingested or inhaled radionuclide is a major problem in radioactive fallout, particularly when prompt evacuation, radioactive monitoring, and remediation have all failed to be carried out, as was the case for both Chernobyl and Fukushima.
IRSN’s assessment of projected doses based on the Japanese map released (see Figure 1), estimated that some 70 000 people including 9 500 children are living in the most contaminated areas outside the initial 20 km evacuation zone projected to receive further doses up to 200 mSv or more. This clearly calls for further evacuation beyond the initial 20 km zone. Under Japanese Food Sanitation Law, 5 000 Bq/kg of radioactive Cs is considered the safe limit in soil. Consequently, large areas of Japan may no longer be suitable for agriculture.
Figure 1 Map of caesium 137 + 134 deposits (Figure 7) superimposed on the map of projected doses for the 1st year (Figure 4) for 3 dose levels only (5, 10 and 20 mSv)
In March 2012, the Japanese government announced a new standard limit for radionuclides in foods to 1 mSv/y, reducing from a previous provisional limit of 5 mSv/y. This translates into a maximum of 100 Bq/kg for regular food items such as meat, vegetables and fish (revised down from 500 Bq just after the Fukushima meltdown), 50 Bq/l for milk and infant food and 10 Bq for drinking water (revised down from 200) . As shown above, this still means an accumulation of internal exposure up to 1 million Bq a year, depending on how fast the radionuclides are cleared from the body. We already know that much lower levels have proven deadly for the children of Belarus (see  Apple Pectin for Radioprotection, SiS 55).
According to the German Society for Radiation Protection, a person is normally exposed to about 0.3 mSv per year through ingestion of food and drink; and this should be considered the permissible level of ingested radioactivity. In order not to go beyond this level, the amount of radioactive caesium-137 should not exceed 8 Bq/kg in milk and baby formula and 16 Bq/kg in all other foodstuff. Radioactive iodine with its short half-life should not be permitted in food at all.
A study led by the Norwegian Institute for Air Research (NILU) found about 16 700 PBq of xenon-133 (250% of the amount released at Chernobyl) emitted by the Fukushima power plant between 12 and 19 March 2011, the largest release of radioactive Xenon in history. In addition, 35.8 PBq of caesium-137 (42% of the amount released at Chernobyl) was emitted in the same period. The study found that radioactive emissions were first measured right after the earthquake and before the tsunami struck the plant, indicating that the quake itself had already caused substantial damage to the reactors. The NILU report also suggests that the fire in the spent fuel pond of reactor 4 may have been the major contributor to airborne emissions, as emissions decreased significantly after the fire had been brought under control.
The same team of researchers updated their estimates in a paper published online giving estimates of 15 300 PBq of Xenon-133 and 36.6 PBq Cs-137 released into the atmosphere, not counting iodine-131 or Cs-134 (which was as much as Cs-137), nor releases into the ocean. But already, this is nearly 15 times the latest TEPCO estimate for total releases. I shall report separately in detail on this latest independent estimate, which gives a global picture of contamination from the fallout (see  Fukushima Fallout Rivals Chernobyl, SiS 55).
I-131 is one of the most acute causes of cancer in children after a nuclear meltdown. Uptake of radioactive iodine can be prevented by a timely supply of iodine tablets. While such iodine tablets were supplied to the municipalities and evacuation centres during the first few days of the disaster, the order to distribute them was never issued, and hence, with very few exceptions, no iodine tablets were taken by people exposed to radioactive iodine. The may lead to a large number of cases of thyroid cancer, as in the case of Chernobyl. And the signs are ominous.
At the end of March 2011, a group of researchers around Hiroshima professor Satoshi Tashiro tested 1 149 children aged 0 to 15 from Iwaki city Kawamata town and Iitate village. Some 44.5 % showed radioactive contamination of up to 35 mSv in their thyroid gland. In October 2011, the University of Fukushima began with thyroid-examinations on 360 000 children living in the regions affected by radioactive contamination. Matsui Eisuke reported some of the results so far . Between October 2011 and 31 March 2012, 38 114 children 1-18 y in Fukushima prefecture were examined by ultrasonography of the thyroid gland. Cysts were found in more than 35 % of the children. In comparison, in Nagaski where 250 children 7-14 y had been examined since 2000, only 2 (0.8 %) had cysts in their thyroid gland.
The government still refuses to evacuate people from the highly contaminated regions. The city of Fukushima organized a planning meeting in the Ônami district that had been recommended for evacuation, and the opening words were:“Evacuation reduces economic activity, so we would opt for decontamination,” in other words, “We won’t let you leave.” The city has designated zones measuring >2 mSv/h for decontamination, and wanted volunteers; but when asked about their decontamination plans, said they have none. In February 2012, an estimated 62 000 people left Fukushima prefecture to seek refuge elsewhere.
In June 2011, pupils from 14 primary and secondary schools from the town of Kôriyama formally demanded that the local authority respect their right to be evacuated and to continue their education in a less contaminated area. But six months later, the demand has been refused.

Highest radiation levels measured outside reactor
Tokyo Electric Power Company says radiation levels are extremely high in an area near a ventilation pipe at the crippled Fukushima Daiichi nuclear power plant.
TEPCO found radiation of 25 sieverts an hour on a duct, which connects reactor buildings and the 120-meter-tall ventilation pipe.
The estimated radiation level is the highest ever detected outside reactor buildings. People exposed to this level of radiation would die within 20 minutes.
The exhaust pipe in question was used to release radioactive gases following the outbreak of the accident 2 years ago.
TEPCO says radioactive substances could remain inside the pipes.

I wonder what the Fukushima apologists will make of this. As if the site isn't contaminated enough; I remember seeing something about one or more of the tall vent pipes being in danger of collapsing due to radiation weakened support struts. This was months ago and the radiation was already too high for workers to work on the weakened struts, even in radiation suits.
If there is as much radioactive material in those vent ducts and stacks as it seems from the story, just how much worse would it contaminate the air and ground around the crippled plant if any of them collapsed and spewed their radiation load on the world.
>> Until now, the utility and regulatory authorities have assured an anxious planet that the contaminants in the water have been primarily tritium. Tritium is a relatively simple isotope with an 8-day half-life. Its health effects can be substantial, but its short half-life has been used to proliferate the illusion that it's not much to worry about. >> >>
Reports now indicate the outflow at Fukushima also includes substantial quantities of radioactive iodine, cesium, and strontium. That, in turn, indicates there is probably more we haven’t yet heard about. >> >>
This is very bad news. >> >> Iodine-131, for example, can be ingested into the thyroid, where it emits beta particles (electrons) that damage tissue. A plague of damaged thyroids has already been reported among as many as 40 percent of the children in the Fukushima area. That percentage can only go higher. In developing youngsters, it can stunt both physical and mental growth. Among adults it causes a very wide range of ancillary ailments, including cancer. >> >> Cesium-137 from Fukushima has been found in fish caught as far away as California.

That these are among the isotopes being dumped into the Pacific is the worst news to come from Japan since Hiroshima and Nagasaki, whose bombings occurred 68 years ago this week, and whose fallout has been vastly exceeded at Fukushima. >> >> Indeed, Japanese experts have already estimated Fukushima's fallout at 20-30 times as high as the 1945 bombings. >> >> This latest revelation will send that number soaring. >> >>

(Reuters) - A strong quake centered off northeastern Japan shook buildings as far away as Tokyo on Friday and triggered a one-meter tsunami in an area devastated by last year's Fukushima disaster, but there were no reports of deaths or serious damage. The quake had a preliminary magnitude of 7.3, the U.S. Geological Survey said, and thousands of coastal residents were ordered to evacuate to higher ground, but the tsunami warning was lifted two hours after the tremor struck.
The groundwater level “inside” of the impervious wall is in the sync with ebb and flow of the sea. In order to shut out the contaminated groundwater from the sea, Tepco built the impervious wall on the coastal line on the seaside of reactor2 building. From Tepco’s own data however, the groundwater level rises and falls as the tide level changes. The trend has become clear since mid-October. It can prove the impervious wall has already started been deteriorated or broken somehow, and seawater and contaminated groundwater are being exchanged again. In the press conference of 11/11/2013, Tepco’s spokesman stated they don’t know the reason.
The groundwater level is found in sync in another place. The location is the seaside of between reactor3 and 4. The underground wall to isolate the area from sea is completed almost 36%. The connection between the ebb and flow of the sea and the groundwater level were not seen through this November, but it’s started being clear since 12/3/2013. There was no significant volume of rainfall before then. There is a possibility that the groundwater is being directly connected to the sea.
At 46:30 in It is still emitting radioactive materials [to the atmosphere] […] not in a gigantic form, but it’s going to keep emitting that for a thousand years or so. I think the only thing they can do with it is cover it over with cement like they did at Chernboyl. At 54:15 in Q: Are we literally on the verge of seeing Japan ceasing to exist as a nation — Is it this serious? A: If we have a serious accident […] or a serious earthquake, yes. The chances are we will get through it. I don’t think that it’s guaranteed that there’s going to be a nuclear holocaust from these events — but there is a high risk.
This thing is no way under control... the Japanese has done everything to suppress the information...
