Fukushima nuclear plant operator Tepco on Monday admitted for the first time that radioactive groundwater is flowing into the sea, fueling fears that marine life is being poisoned.
The admission came a day after voters handed the largely pro-nuclear Liberal Democratic Party of Prime Minister Shinzo Abe — and ally New Komeito — a handsome majority in the Upper House.
Earlier this month, Tokyo Electric Power Co. said groundwater samples taken at the battered plant showed that levels of cesium-134 had shot up more than 110 times in a few days.
Although unable to explain the increased readings, Tepco had nevertheless maintained the toxic groundwater was likely being contained, largely by concrete foundations and steel sheets.
“But now we believe that contaminated water has flowed out to the sea,” a Tepco spokesman said Monday.
However, the spokesman insisted the impact of the radioactive water on the ocean would be limited. “Seawater data have shown no abnormal rise in the levels of radioactivity.”
Tetsu Nozaki, chairman of Fukushima Prefectural Federation of Fisheries Co-operative Associations, voiced deep concern.
“It was quite shocking,” he told NHK. “(Tepco’s) explanation is totally different from the one in the past.”
Fishing around the Fukushima plant was halted shortly after the crisis, and production of beef, milk, mushrooms and vegetables was banned in surrounding areas, crippling the prefecture’s thriving fishing and agriculture industries.
Tepco, which is surviving thanks to a massive infusion of public funds, said it would step up efforts to reduce underground water by consolidating soil near its harbor.
Radioactive substances released by the reactor core meltdowns at the aging plant following the huge quake and tsunami of March 2011 have been leaking from damaged buildings and mingling with the ground water, which usually flows out to sea.
Environmental experts warn that the festering radioactive sore could contaminate the food chain by tainting marine life and ultimately, the humans who eat it.
Tepco said earlier this year that a fish found with radiation more than 2,500 times the legal limit had been caught in a port on Fukushima No. 1′s premises. It also said last week that around 2,000 people who worked at the plant now face a heightened risk of thyroid cancer.
This is 10 times more than Tepco’s previous estimate for potential thyroid cancer victims and came after the beleaguered utility was told its figures were too conservative.
Since the Fukushima accident, everyone understands the situation as h eperceives it to be and everyone is right, it is very serious indeed, but still we haven’t seen almost anything yet. And what we may risk to see and understand?
When sharing the galette des rois, some cookies are stuffed with a a small gold coin (a gold Napoleon). If a greedy one swallows it inadvertently, he will have to wait one to two days to recover it but his health will not be affected.
Imagine the coins gold plated and filled with actinides (highly toxic alpha radiotransmitters) such as:
They all weigh 6 grams, have a diameter of 21 mm and the same visual appearance.
A) gold plated Uranium 238
B) gold plated Plutonium 239
C) gold plated Plutonium 238
D) gold plated Polonium 210
We will not see any difference in appearance and weight.
You swallow any of those and nothing happens, either immediately or later.
The the lethal dose threshold of an inhaled monolithic dust is:
0.835gram for A
0.000 000 4 gram for B
0.000 000 001 6 gram for C
0.000 000 000 007 gram for D
This means that the lethal dose of these coins could destroy:
6 lives for A (Uranium 238, there is a lot)
13,475,000 lives for B, more than Paris Metropolis population (Plutonium 239,there is a lot)
3700000000 lives for C, more than half of mankind (Plutonium 238 is rare)
850 billion lives for D, 120 times the world’s population. (Polonium 210 is very rare)
Yet these coins A, B, C and D have not caused you any damage after being swallowed, not even long after. Because they were all covered with a tenth mm of gold , which prevented the huge flow of alpha particles to destroy even just a little of your digestive tract.
Conclusion:alpha emitters radionuclides must remain CONFINED.
Avoid that nuclear plants explode, even one, especially those using MOX,such as the ones which are many in France.
this, are you still willing to fight FOR nuclear power?

Cesium soars in water under No. 1 plant
Tokyo Electric Power Co. on Tuesday reported a surge in radioactive cesium levels in groundwater in an observation well at its Fukushima No. 1 nuclear power plant.
This signals radioactive contamination is spreading under the disaster-stricken facility.
Water sampled from the well Monday contained 9,000 becquerels of cesium-134 per liter and 18,000 becquerels of cesium-137, both about 90 times the levels found Friday, Tepco said. The well is near the turbine building for reactor 2 and about 25 meters from the plant’s harbor.
“We still don’t know why the level of radiation surged, but we are continuing efforts to avert further expansion of contamination,” a Tepco spokesman stated.
Government guidelines permit cesium-134 at 60 becquerels per liter and -137 at 90 becquerels. Once ingested, the substances accumulate in muscle and bone and are believed to cause cancers.
The water collected Monday also contained 890,000 becquerels of substances that include strontium, which emits beta radiation, compared with 900,000 becquerels found in groundwater sampled from the well Friday.
Groundwater cesium levels in the well and other observation wells had remained low until recently. Readings were often below the minimum detectable levels.
Explaining the reason for the low contamination in groundwater, Tepco had said cesium can be easily absorbed by soil.
Following the latest findings, however, Tepco officials now say they do not know why the cesium levels have surged.
“Mud that has absorbed radioactive cesium may have got mixed with the water. We will measure the (contamination of the) water again,” a Tepco official told reporters at the Fukushima Prefectural Government office.
The official also said Tepco will determine if radioactive substances are seeping into the sea after studying its seawater survey.
The company also said groundwater collected Monday from a well located near the reactor 3 turbine building and about 23 meters from the port was found to have contained 1,700 becquerels of beta radiation-emitting substances per liter.
The reading was about 20 times the level detected Thursday and the highest for such substances in the well.
The new readings came two days after Tepco said tritium, a radioactive isotope of hydrogen used in glow-in-the-dark watches, was present at levels 10 times the permitted rate.
Tepco said in late June it had detected the highly toxic strontium-90, a byproduct of nuclear fission that can cause bone cancer if ingested, at levels 30 times the permitted rate.
The substances, which were released by the meltdowns of reactors at the plant in the aftermath of the huge tsunami of March 2011, were not absorbed by soil and have made their way into groundwater.
Subsoil water usually flows out to sea, meaning these two substances could normally make their way into the ocean, possibly affecting marine life and ultimately impacting humans who eat sea creatures.
Last August the Tokyo Electric Power Company (TEPCO) estimated 15,000 tera becquerels of cesium radiationhad leaked from the Fukushima Nuclear Power Plant in Japan.
One tera becquerel equals 1 trillion becquerels.
At that time, the estimated cesium release was ‘equal 168 Hiroshima bombs’ as the atomic bomb atomic bomb dropped on Japan during World War II had only released 89 tera becquerels of cesium.
On Wednesday, TEPCO releasedrevised estimates of the amount of radiation leaked from Fukushima.
The new estimated calculated the level of cesium released to be 360,000 tera becquerels.
That is 24 times higher than last August’s estimate and represents a cesium leak equal to 4,023 Hiroshima bombs.
The estimate is also more than 4 times Chernobylwhich is estimated to have released 85,000 tera becquerels of cesium radiation into atmosphere.
TEPCO’s newly revised estimates of the Fukushima leak are also not all-inclusive and do not cover the entire date range from the start of the disaster.
The estimate of the total atmosphere release is based on data collected from between March 12 to 31, 2011,
TEPCO states the amount of radiation released into the atmosphere in April and during the following months is likely to be only 1% of the amount released in March.
That amount is considered to be ‘insignificant’ and is not included in the new estimate.
The estimated amount of radiation leaked into Pacific Ocean was extrapolated from data collected from March 26 to September 30, 2011.
TEPCO warned this data was collected from a ‘small amount of data acquired in a limited area’ and further warned ‘further data still needs to be collected to review the validity’ of their estimates.
The new estimate also did not provide figures for the amount of radiation leaked into the water pits that run beneath the Fukushima’s nuclear reactors or for radiation leaked into contaminated water that TEPCO has collected into storage tanks.
Last June, TEPCO estimatedthe amount of radiation leaked into the underground water pits to be up to nearly to two times higher than the amount of radiation released into the atmosphere.
«The World Health Organisation (WHO) is failing in its duty to protect those populations who are victims of radioactive contamination.»
Last Friday 5th July 2013 I went to participate for few hours to the Independent WHO’s vigil in Paris in front of the French Ministry of Health, where I met a few Anti-nuke veterans,
I believe that this Vigil is in fact particularly important, as it denounces the treacherous 1959 agreement made betwween the WHO and the IAEA, with a continuous citizen’s presence demanding due real protection from the WHO and each country’s Health Department,
I do think it would be great if the Vigil was extended from Geneva and Paris in Europe to USA and Japan, by having the American people also having a vigil in front of their own Health Department in Washington D,C, and the Japanese people as well in Tokyo in front of Japanese Health Ministry, so that people on 3 continents would be united in denouncing that devious agreement, demanding for its reviewing and its revocation, as this agreement is maintaining a conflict of interest keeping the WHO subservient to the nuclear own interests of the IAEA, therefore blocking the WHO to perform its dued mission of protecting internationally the people from all kinds of sanitary dangers
The Vigil for June 2013 – Geneva and Paris
« Since April 26, 2007, the Hippocratic Vigil has been held outside the WHO headquarters in Geneva, which now makes a total of 322 weeks without interruption. The vigil consists of a silent presence that aims to remind the World Health Organization of its obligations as set out in its constitution. We have added the name of Hippocrates to our description because of the ethical rules he instituted for health practitioners. As far as the protection of the health of people affected by the consequences of the nuclear industry is concerned, the World Health Organization ignores these rules.
The Vigil takes place outside the WHO headquarters in Geneva every working day from 8:00 am to 6:00 pm and in Paris every Friday from 9:00 am to 5:00 pm.
We now believe it is important to address ourselves to those who are partly responsible for deciding WHO policy. It is for this reason that, on 9th November 2012, we began a Vigil outside the Ministry of Health in Paris. The Ministers of Health are the representatives of the member countries of WHO, and they are involved in deciding the policies and actions that this institution pursues in the area of radioprotection.
We will maintain this silent and peaceful vigil every Friday from 9am to 5pm outside the Ministry of Health in Paris, until France takes the necessary steps to ensure that WHO fulfils its mission to protect the population from radioactive pollution, and that a programme of independent research is put in place on a national and / or European level, on the theme of “Health and nuclear power”.

TEPCO. has seen a rise in the level of radioactive tritium in seawater within the harbor at the crippled Fukushima No. 1 nuclear power plant.
A sample collected Friday contained around 1,100 becquerels of tritium per liter, the highest level detected in seawater since the nuclear crisis at the plant started in March 2011, the utility said Monday.
An official of the Nuclear Regulation Authority said groundwater containing radioactive substances may be seeping into the harbor from the plant site and there is a need to carry out a careful investigation because the data collected so far are limited.
The sample with the highest tritium concentration was collected near a water intake on the east side of the reactor 1 turbine building. Its level was more than double that of a sample taken on June 10 in the same area.
