In the case of Chernobyl, a significant part of the nuclear power had been released by the explosion.

In the case of Fukushima, it is still almost intact, and it puts us directly at the mercy of its deadly pollution (since the beautiful illusion of containment enclosures is still one of the best kept lies, of the entire industrial era ).

Nuclear threats are a kind of Russian roulette situation, continuous threats, with the finger on the trigger ... the fallibility and incompetence of men, and the ultimate expression of their vanity since many "still want to believe it to the end"!

Threats to the lives of millions of people, threats to economies, threats to heritage, threats to local products becoming deadly poisons ... Threats to the civilization of a humanity or "man is good only to be thrown", But this is not fair for a workplace and potentially for millennia ...

Nuclear experts have recognized it themselves, and among the best (including one from EPFL - yet in the pay of this industry - who describes these situations himself "experimental"). And they would still like to skip the steps with the EPR ... While nothing is resolved!

Therefore, if they continue to do everything they can to cool down in Japan, it is because they fear it all too well the consequences which remain as unpredictable as disturbing.

However, it would be wrong to believe that the danger only comes from Fukushima and to let our guard down. Barrels with large caliber of "non-depleted" fuel, there are tons of them everywhere in power stations scattered all around the planet, the critical conditions are no longer lacking in order for things to blow up again elsewhere.

The worst part of all this is that the United Kingdom has apparently not become aware of the nuclear risk and wishes to relaunch its civil program ...

Why do we build nuclear power plants if we can't even measure the temperature of the water in the pool?

Regarding the 10 Sv, it would be a leaking pipe .... repaired since ...

Regarding the reactor 1 pool where the measuring devices are supposedly faulty, I hope this is not a way for Tepco not to disseminate disturbing figures ....

I do not understand how 5 months after the explosions there can be more than 10 Sieverts / h for a radioactivity dating from March 12 or 13 ????

Strange, this lack of decay ?????
.

Otherwise, after the straw, the meat, the fertilizing soil, the rice has become radioactive and all of eastern Japan is blocked under controls, endlessly well beyond the exclusion zone, so as not to feed the Japanese with radioactive !!

Highest radioactivity level detected at nuke plant

The operator of the Fukushima Daiichi nuclear power plant says it has detected 10,000 millisieverts of radioactivity per hour at the plant. The level is the highest detected there since the nuclear accident in March.

Workers of Tokyo Electric Power Company, or TEPCO, on Monday measured the extremely high level of radioactivity near pipes at the bottom of a duct between the No.1 and neighboring No.2 reactor buildings.

According to the science ministry's brochure, if a human received 10,000 millisieverts, they would likely die within a week or two.

TEPCO has restricted access to the site and the surrounding area.

The utility says the workers taking measurements on Monday were exposed to up to 4 millisieverts.

The utility says the high level of radioactivity was detected because the pipes were used to vent air containing radioactive substances from the crippled No.1 reactor on March 12th.

The utility had detected a maximum of 1,000 millisieverts per hour outdoors in debris, and also found a maximum of 4,000 millisieverts per hour indoors in one of the reactor buildings.

Govt sets new criteria for contaminated fertilizer

Japan's government has laid down a new set of criteria for the use of fertilizers that may be contaminated with radioactive cesium.

On Tuesday, the agriculture ministry urged farmers not to use humus and compost that contain 400 becquerels of cesium per kilogram or more.

It also called on them not to use livestock feed containing 300 becquerels of cesium per kilogram or more. For fish feed, the limit was set at 100 becquerels per kilogram.

The ministry says it will notify local governments how to measure cesium in fertilizers as soon as possible.

Last week, the agriculture ministry asked famers and fertilizer producers in 17 prefectures in eastern and central Japan to voluntarily refrain from using or selling compost and humus made from fallen leaves possibly contaminated with radioactive cesium.

This was after humus shipped from Tochigi Prefecture was found to be contaminated with radioactive substances.

Govt bans shipments of Tochigi beef cattle

Japan's government has ordered Tochigi Prefecture to suspend its shipments of beef cattle due to fears of radioactive contamination.

The government ordered the ban on Tuesday after beef from 4 heads of cattle shipped from 2 municipalities in the prefecture was found to contain unsafe amounts of radioactive cesium.

Cesium contamination was also detected in rice straw used to feed beef cattle in the prefecture.

Tochigi is the fourth prefecture ordered to suspend beef cattle shipments, following Fukushima, Miyagi and Iwate.

The government says it will allow resumption of shipments if radiation levels of all beef from farms whose shipments and feed were contaminated, as well as beef from other farms, fall below the government standard.

Tochigi says it will test all of its beef cattle, but the prefecture ships up to 55,000 head of cattle per year, and fewer than 30,000 can be processed locally.

The government is to ask the prefecture to draw up realistic plans for summarizing shipments, such as limiting the number of cattle to be shipped.

The radiation level at Fukushima was 1000 times the maximum radiation level from an H bomb !!
and 300 times that of Chernobyl !!


Fukushima Radiation 1,000 Times H-Bomb Peak
http://www.veteranstoday.com/2011/08/02 ... mb-peak-2/

Busby certified the poisonous, radioactive Japanese air to be at least 300 times worse than the air during the Chernobyl nuclear reactor disaster. Dr Janette Sherman, a highly respected physician and an acknowledged expert in radiation exposure, has estimated the world wide Chernobyl Kill to be at least one million people killed to date. The Chernobyl Disaster occurred April 26, 1986.
The estimates must be considered as conservative or low since the smallest particles go through the car air filters and emerge from the car's exhaust. The smallest radioactive particles simply go through a human's skin or go to the bottom of a human's lungs and stay there. The poison radiates cells within a range extending 20 cells deep in all directions. The dead and dying or mutated cells become cancers and hundreds of other radiation related diseases.

Consequences in Japan of the Fukushima Daiichi accident: massive, lasting and very widespread contamination (CRIIRAD) 67 documents
Wednesday August 3, 2011.


The CRIIRAD laboratory carried out a mission to Japan from May 24 to June 3, 2011 [1]. This document presents the findings from the first analysis results. The radioactive cesium deposits on the soil were very important. They generate, and will generate for a long time, a flux of gamma rays responsible for the irradiation of the population over very large areas. In the absence of protective measures, hundreds of thousands of inhabitants will receive, due to this external exposure, radiation doses far above the limit of 1 mSv / year. To this must be added internal exposure (mainly due to the ingestion of contaminated food) and especially all the doses received since March 12, doses that may have been extremely high during the first week due to the virtual absence of protective measures.

1 / Importance of contamination over 60 km: the example of the city of Fukushima

External irradiation leads to an unacceptable level of risk

Field measurements and soil analyzes carried out by the CRIIRAD laboratory on the city of Fukushima, located 60-65 km from the Fukushima Daiichi nuclear power plant, indicate that the fallout of cesium 134 and 137 radioactive is several hundred thousands of Bq / m2: 490 Bq / m000 on the lawn of the Moriai primary school; more than 2 Bq / m700 in the Watari district.

By disintegrating, the cesium atoms emit very penetrating gamma radiation. They can travel in the air for more than 60 meters, which has enabled the Americans to establish a fallout map using helicopter-borne probes. This radiation also passes through the walls and windows of homes and irradiates people in their homes.

At the end of May 2011, the dose rates recorded by CRIIRAD in the city of Fukushima, 1 meter above the ground, outdoors, were typically more than 10 times, even more than 20 times higher than normal (greater than 1 and 2 μSv / h). Irradiation is still measurable in the floors of buildings. Measurements taken on the 4th floor of a building showed an excess of radiation which increases when approaching the windows (even closed). Inside a single-family house in the Watari district, CRIIRAD measured a dose rate more than 3 times higher than normal in contact with the tatami in the children's room (0,38 μSv / h) and 6 times higher in the living room at 1 meter from the floor (0,6 μSv / h). In front of the house, we measure, 2,2 μSv / h in the pleasure garden and 2,9 μSv / h at the lawn of a nearby school (measurements at 1 meter from the ground).

This irradiation will only decrease very slowly. It is mainly due to cesium 137 and cesium 134 whose physical periods are long (30 years and 2 years respectively). This means that the radioactivity of cesium 137 will be halved in 2 years. It can be estimated that over the next twelve months, the radioactivity of cesium 30 will only be reduced by 134% and that of cesium 30 by 137%. The ambient radiation will only be reduced by a few tens of%.

If nothing is done, the inhabitants of the city of Fukushima could undergo in the next twelve months an external irradiation of several milliSieverts when the dose beyond which the risk of fatal cancer is considered unacceptable by the ICRP (Commission International Radiological Protection) is 1 milliSievert per year, which corresponds to 5 deaths per 100 people exposed.

However, the Japanese authorities have set a dose limit of 20 milliSieverts as a criterion for deciding whether to permanently evacuate populations. This corresponds to a risk of fatal cancer in the long term 20 times higher than the acceptable risk. This is all the more serious as the residents of Fukushima have already been severely exposed. It is also necessary to take into account the doses linked to internal contamination that these populations continue to undergo by ingestion of contaminated foodstuffs and the risks linked to the inhalation of dust from the contaminated soil.

In the city of Fukushima, the CRIIRAD measured for example in the soil taken from the swings of the Moriai primary school, cesium 137 + 134 contamination of 370 Bq / kg. This soil has become radioactive waste which should be stored as soon as possible at an appropriate site.

A population already very exposed to radiation

The persistence of iodine-131 contamination in the soil collected by CRIIRAD at the end of May 2011 in the city of Fukushima makes it possible to assess the initial fallout in iodine-131 at millions of Bq / m2.

Iodine 131 has a physical period of 8 days, so its radioactivity was more than 600 times greater during fallout. This testifies to the strong contamination of the air during the arrival of the contaminated plumes in particular on March 15, 2011.

There were also other radioactive substances which have largely disintegrated since such as cesium 136, tellurium 129, tellurium 132, iodine 132, iodine 133, etc. as well as radioactive gases such as xenon 133 and krypton 85 which are not accumulated in the soil.

The inhabitants of this city have therefore already been subjected to a very significant internal contamination first by inhalation of contaminated air and especially by ingestion of foodstuffs contaminated due to the deposits of radioactive substances. The Japanese authorities did not enact consumption restrictions on Fukushima prefecture until March 21 and 23 (depending on the type of food). The populations therefore consumed highly contaminated food for more than a week, without any restrictions or information. They were therefore able to receive effective doses of several tens of milliSievert and the thyroid doses exceeding the Sievert.

As a reminder, the initial contamination of spinach with iodine-131, 100 km south of the power station, was such that by consuming 200 grams a young child could exceed the maximum admissible annual dose of 1 milliSievert, 40 km north-east west, plants were so contaminated that this annual limit could be reached by consuming 5 grams of plants.

It is essential that the affected populations obtain a reliable evaluation of the doses already undergone and it is imperative to do everything to limit their future exposure.

2 / Size of the area affected by the fallout

The fallout relates to a very large territory, well beyond the 20 km prohibited zone and well beyond the Fukushima prefecture. Depending on the weather conditions, the contaminated air masses moved over hundreds of kilometers and the precipitation (rain and snow) entrained the radioactive particles on the ground. Cesium 134 and 137 deposits cause lasting contamination.

This is confirmed by the soil samples and by the dose rate measurements carried out [2] by CRIIRAD (1 meter above the ground), from May 24 to June 3, 2011. We measure:

0,47 μSv / h in Marumori (Miyagi prefecture), about 60 km north of the plant. The calculated natural level [3] is 0,1 μSv / h and the fallout [4] in cesium 137 and 134 is more than 95 Bq / m000.

0,33 μSv / h near Hitachi (Ibaraki prefecture) about 88 kilometers south of the plant. The calculated natural level is 0,07 μSv / h and the cesium fallout is more than 50 Bq / m000.

Iodine 131 is still detected in the May 25 sample.

0,28 μSv / h at Ishioka (Ibaraki prefecture) about 160 km south southwest of the plant. The calculated natural level is 0,06 μSv / h and the cesium fallout is more than 48 Bq / m000.

There are therefore, in both the Ibaraki and Miyagi prefectures, sectors in which the rate of artificial radiation is more than 4 times higher than the natural level. This therefore represents for a person who spends 50% of his time outdoors, a dose added over the next twelve months likely to exceed the maximum admissible annual dose of 1 milliSievert per year, without taking into account, nor the external irradiation induced at inside buildings, nor from internal contamination by ingestion of contaminated food or by inhalation of resuspended radioactive particles.

These results contradict the information relayed by the French Nuclear Safety Authority, which wrote in a press release dated June 28, 2011: “Outside the site, the decrease in dose rates measured in the environment continues. In Fukushima on June 7, the dose rate was 1,6 μSv (microSievert) / h. The 45 other prefectures have dose rates of less than 0,1 μSv / h ”.

In the city of Tokyo, the residual exposure by external irradiation is likely to lead to a significant exposure. For example, CRIIRAD measured 0,14 μSv / h at the beginning of June, in the Wadabori-Koen park, in Tokyo (about 235 km from the power plant). In this park, the calculated natural level is 0,06 μSv / h and the cesium 134 and 137 fallout of more than 14 Bq / m000. Data should be available for the entire agglomeration.

This is why CRIIRAD asks Japanese citizens to demand the publication of detailed maps of fallout and residual contamination, nationwide, and with sufficient precision, i.e. corresponding to Cesium fallout from 1 Bq / m000 and not from 2 Bq / m300 as on the maps published on May 000, 2.

Notes

[1] A first assessment of the investigations was presented at press conferences in Fukushima (May 30) and Tokyo (May 31 and June 1, 2011) and are set out in a report available on the CRIIRAD website (in English) : available on ESSF (article 22247): Fukushima: Preliminary comments - CRIIRAD mission in Japan.

[2] Measurements carried out by Christian Courbon, Bruno Chareyron (CRIIRAD laboratory) and Wataru Iwata (Japanese NGO Project 47) using a proportional energy compensated meter, model LB123 of the Berthold brand.

[3] Since contamination is detectable everywhere including in Tokyo, it is difficult to determine the rate of natural radiation in the absence of contamination. From soil analyzes that made it possible to measure the activity of natural gamma-emitting radionuclides, the CRIIRAD laboratory recalculated the theoretical natural dose rate (telluric component and contribution of cosmic radiation).

[4] These are estimated fallout from the cesium 137 and cesium 134 concentrations measured on the 0-5 cm stratum of a core sampled on flat, undisturbed land and therefore likely to have correctly preserved the deposit. took place in March 2011. The surface activity given is a preliminary estimate by default as the analysis of 5-10 cm strata and fractions> 2 mm continues.

Mas non dit Jancovici in its course, all this is harmless, below 200millisieverts / year, it is not documented (200 times the natural radioactivity, or 16 sieverts in a lifetime of 80 years, while a few Sieverts get you down and kill you with certainty quickly with excruciating pain) !!!

It should be noted that the ICRP indicates that 1 millisievert per year (natural radioactivity) corresponds to 5 deaths per 100000 people exposed also per year !!
So in 80 years of life it is about 80 times more deaths (much more on exposed fetuses) or 400 cancers per 100000 inhabitants !!
And the typical radioactivity of 20 times that natural all around for more than 100km leads to 20 times more additional cancers or 8000 for 100000 close to 1 for 10 inhabitants !!
A hecatomb of shortened lives, especially that cancers are not the only way to die, with lots of other diseases as devastating that kill slowly by radiation! !! The liquidators of Chernobyl suffered them and it is classified in fear of radiation !!

20 times the natural radioactivity is 1,6 Sieverts (or gray) in a life of 80 years which kills slowly with almost certainty long before !!

The nuclear lobby is criminal and its officials will have to answer for their criminal lies !!


The Japanese will see multiply diseases, first thyroid, in children then many others (not only cancers) as for Chernobyl !!

Mongolia: Will the country become the world's nuclear trash?

The rumor has been circulating for several months; the Chinese are worried about it. For the first time, the local press reported this. And some fear that this is true: Japan and the United States are about to bury their nuclear waste in Mongolia.

Mongolian plateau and ruins.

Landlocked between Russia and China, the Mongolian landscape is made up of vast natural plateaus. Before being contaminated by nuclear waste? © GAMMA

Last March, press articles evoked the subject. The United States and Japan are said to be preparing to sign an agreement with Mongolia to export their nuclear waste. At the time, the foreign ministry quickly declared that these “rumors” were baseless. He recalled that an article of the Mongolian constitution prohibited "the importation of hazardous waste in Mongolia".

However, an article dating from mid-July in the Japanese daily Mainichi Daily News revived the rumor. As with the articles at the start of the year, the Chinese press reacted violently. The Middle Kingdom is worried that nuclear waste from two of its most important strategic threats will be deposited at its door. Some even suspect that they want to make a nuclear discharge at the gates of China the ultimate weapon in the event of conflict.

An unpopular project

Besides the Chinese, the newspapers of the first interested parties also reacted. In the UB Post, L.Selenge, head of the “Mongolian Green Coalition”, expresses his anxiety about this project:

- UB Post: How did you receive information about the plan from the United States and the Japanese?

- L. Selenge: By the press. After the new article in the Mainichi, we asked the authorities to speak on the subject. The Ministry of Foreign Affairs did not see fit to answer us. We interviewed the Mainichi who assured us that it was based on official documents and would take responsibility for its article. It is one of the most serious daily newspapers in the archipelago, so it seems difficult to doubt their revelations. The government has exposed the Mainichi revelations, but it has the right, if it is a lie, to sue the newspaper. If he has not done so, there is a good reason.

- UB P.: Who do you think is responsible for the discussions in the Mongolian camp?

- LS: The Ministry of Foreign Affairs. Undraa Agvaanluvsan is responsible for nuclear affairs. She has lived in the United States for a long time and even has a green card. We suspect her of being the culprit…

We will have to wait a bit to learn more about these amazing projects. The Chinese will certainly put all their energy into making the business fail. Already scalded by the contamination from the Fukushima disaster (without Japan having ever seen fit to communicate transparently on the situation), China would like to avoid finding itself close to the global nuclear waste bin.

ubpost.mongolnews.mn


Anything bad is good, it would be good that they eat their noses all these dangerous irresponsible. This would allow us to finally talk about this waste of waste that nobody wants, except to smuggle it in to the others by corrupting it over and over again ... : Cry: :| : Shock: : Evil:
