Fukushima timeline - July 2011
- Radioactive debris dilemma unresolved, growing worse
No grand plan; hot spots spread; schools just hide dangerous soil
- Radiation detected in Fukushima children's urine
A group of Japanese citizens says radioactive materials have been detected in urine of 10 children in Fukushima Prefecture, where the troubled Fukushima Daiichi nuclear power plant is located.
The Fukushima Network for Saving Children from Radiation collected urine samples from 10 elementary to high school students in the prefecture's capital Fukushima City. The samples were analyzed by a French research organization.
The group said at a news conference in Tokyo on Thursday that radioactive cesium was found in all of the samples, and that one from an 8-year-old girl contained 1.13 becquerels of cesium-134 per liter.
- TEPCO denies new leak at Fukushima plant
Radioactive tellurium-129m was detected for the first time in seawater near the water intake of the Fukushima No. 1 nuclear power plant's No. 1 reactor, Tokyo Electric Power Co., the plant operator, said June 29.
Seven hundred and twenty becquerels of the substance was detected per liter of water collected on June 4. This concentration is about 2.4 times safe levels.
Tellurium-129m has a short half-life of about 34 days. Its detection near the intake indicates the possibility of a new leak of radioactive water into the sea.
TEPCO, however, said a new leak was unlikely because there wasn't a sharp increase in other radioactive substances and because tellurium- 129m was detected only at this single sampling point near the water intake.
- 113 households identified as radioactive hot spots
The central government on Thursday designated 113 households in Date, Fukushima Prefecture, as areas with radioactive hot spots and recommends that the people living there evacuate despite being outside the no-entry zone around the Fukushima No. 1 nuclear power plant.
The areas include 113 households in the Ishida, Kamioguni and Shimooguni districts in the Ryozenmachi area, and the Aiyoshi district in the Tsukidatemachi area, where cumulative radiation is expected to exceed the government standard of 20 millisieverts a year.
- TEPCO moves low level contaminated water
Workers at TEPCO's Fukushima Daiichi nuclear power plant have started moving low level contaminated water to a giant steel barge for storage.
The transfer from the plant's make-shift tanks started on Thursday afternoon to the barge called the "mega float." The barge is attached to a quay on the plant's premises.
I m getting a feeling that NHK reporters are following this website ;)
- Cesium found in child urine tests
Cesium-134 and cesium-137 were detected in the urine samples of all 10 children aged between 6 and 16 who participated in the survey. The largest amount of cesium-134, which has a half-life of two years, was 1.13 becquerels per liter, found in the urine of an 8-year-old girl.
As for cesium-137, which has a half-life of 30 years, the largest amount was 1.30 becquerels per liter detected in a 7-year-old boy. No traces of iodine-131 were found in the test.
The government has set a safety limit of 200 becquerels of cesium per liter of water.
The samples were taken in late May in the city of Fukushima, more than 50 km from the Fukushima No. 1 plant.
"All (tested) kids are contaminated. . . . Currently the (government's) policy is mainly on external exposure, but internal exposure should be taken into consideration," ACRO Chairman David Boilley told a news conference in Tokyo.
- Radioactivity survey ship leaves for Fukushima
Professor Takashi Ishimaru, the team's leader, says it's important to provide accurate information because without data, people tend to become suspicious and they might create groundless rumors.
- Saga Prefecture set to restart reactors at Genkai nuclear plant
Saga Governor Yasushi Furukawa said he will approve the restarting of two reactors at a nuclear power plant in the prefecture that have been shut down for months due to regular inspections.
Furukawa's green light is a cause for concern among local governments wary of restarting nuclear reactors--even if the central government OKs such plans--because of growing safety concerns following the accident at the Fukushima No. 1 nuclear power plant.
Furukawa's gesture came after economy minister Banri Kaieda urged him to do so in a meeting June 29.
- Workers enter No. 4 reactor building
Workers entered the fifth floor of the building on Wednesday for the first time since an explosion on March 15th.
The radiation level inside the building was less than one millisievert per hour...
5th floor of building no.4 and the word "inside" dont seem to fit well together.
- Another worker exposed to high radiation
The limit radiation exposure was raised from 100 millisieverts to 250 millisieverts after the Fukushima accident to secure enough time for workers at the plant to bring the situation under control.
Raising radiation limit to deadly levels = securing enough time for workers. Do i read that right?
- Human error blamed for cooling system halt
But the system, which is designed to recycle cooling water after removing radiation from it, has been suspended several times.
Trouble has been occurring particularly frequently with the decontamination device, mainly because of human error.
Radiation has nothing to do with it.... But what if its actually true? Human Error. Look at the video by AlJazeera below!
- TEPCO to enhance manual on coolant system
The operator of the troubled Fukushima Daiichi nuclear power plant says it will improve the content of operation manuals for a newly introduced reactor coolant system. The move is intended to prevent human errors from causing suspension of the cooling operation.
More reasuring news... Upgrading the manual. Please look at the video by AlJazeeraEnglish below.
- TEPCO starts using megafloat to store low-level radioactive water
The water comes from the Nos. 5 and 6 reactor turbine buildings and a large part of it is believed to be seawater left inside the facilities after large tsunami waves hit the plant on the Pacific Coast in Fukushima Prefecture, as well as groundwater.
Dealing with the massive amount of water contaminated by radioactive substances in various degrees is a key part of the process to contain the ongoing nuclear crisis, triggered in the wake of the March 11 devastating earthquake and ensuing tsunami.
Meanwhile, to reduce the highly radioactive water which is created by continuous cooling of crippled nuclear reactors, Tokyo Electric is operating devices that take away radioactive substances from the polluted water and a system to recycle the decontaminated water as a coolant for the reactors.

- Japan's desperate 'nuclear gypsies'
With the current economic downturn, many of Japan's poorest are so desperate for work that they are risking exposure to dangerous levels of radiation at the damaged Fukushima nuclear plant.
The growing number of so-called nuclear gypsies, who come from across the country, are working to repair the reactor crippled by the March 11 tsunami in the northern city of Osaka. Its a job with severe health risks that most are not willing to brave.
Labour rights groups have complained to authorities about the lack of protection for the workers - who are not guaranteed training or health insurance.
Step Vaessen reports from Osaka.
- Revealed: British government's plan to play down Fukushima
Leaked emails show PR campaign was launched to protect UK nuclear power plans after tsunami in Japan
British government officials approached nuclear companies to draw up a co-ordinated public relations strategy to play down the Fukushima nuclear accident just two days after the earthquake and tsunami in Japan and before the extent of the radiation leak was known.
Internal emails seen by the Guardian show how the business and energy departments worked closely behind the scenes with the multinational companies EDF Energy, Areva and Westinghouse to try to ensure the accident did not derail their plans for a new generation of nuclear stations in the UK.
"This has the potential to set the nuclear industry back globally," wrote one official at the Department for Business, Innovation and Skills (BIS), whose name has been redacted. "We need to ensure the anti-nuclear chaps and chapesses do not gain ground on this. We need to occupy the territory and hold it. We really need to show the safety of nuclear."
