Estimated radiation doses of Fukushima returnees withheld for half a year
April 16, 2014
THE ASAHI SHIMBUN
The government withheld findings on estimated radiation exposure for Fukushima returnees for six months, even though levels exceeded the long-term target of 1 millisievert a year at more than half of surveyed locations.
Individual radiation doses were estimated to be beyond 1 millisievert per year, or 0.23 microsievert an hour, at 24 of all the 43 surveyed sites, including ones in the Miyakoji district in Tamura, Fukushima Prefecture, The Asahi Shimbun learned April 15.
The revelation comes just two weeks after the central government lifted the evacuation order for the district on April 1.
Last July, the Cabinet Office’s working team in charge of assisting the lives of nuclear disaster victims asked the National Institute of Radiological Sciences and the Japan Atomic Energy Agency to measure air dose rates and estimate individual radiation doses at 43 locations.
The survey covered seven types of living spaces, including private residences, farmland and schools, in the prefecture’s three municipalities of Tamura, Kawauchi and Iitate.
The government’s decontamination work aims at bringing radiation levels in contaminated areas to within 20 millisieverts a year before it gives the go-ahead for residents to return.
It also intends to bring readings to 1 millisievert or less eventually. The International Commission on Radiological Protection says a reading of up to 20 millisieverts is acceptable in areas where cleanup is under way.
The central government has also proposed to distribute devices that measure individual radiation to returned evacuees, so residents can monitor their radiation doses on their own.
But some evacuees from areas affected by the Fukushima No. 1 plant nuclear accident, which was triggered by the 2011 earthquake and tsunami disaster, worry about the possibility they may be exposed to high radiation doses after returning to their homes.
For this reason, the government decided to study correlations between air dose rates and individual radiation doses around the crippled facility to prove that the amount of radiation to which residents will be exposed is sufficiently low, even when air dose rates are relatively high.
The National Institute of Radiological Sciences and the Japan Atomic Energy Agency last fall measured radiation levels at several dozens of spots at each of the 43 sites in the three municipalities. They found that individual radiation doses are typically 30 percent lower than air dose rates.
The government-affiliated bodies also discovered that average air dose rates exceeded 0.23 microsievert per hour at 27 of the 43 sites, while they estimated individual radiation doses at over 0.23 microsievert an hour at 24 locations.
In mid-October, the two agencies compiled a midterm report and submitted it to the government. But the Cabinet Office’s working team did not disclose the report until the evacuation order for the Miyakoji district was lifted. According to a member of the team, this was because the finding “has no direct relationship with lifting the evacuation orders.”
Although the government held numerous meetings with Miyakoji residents to discuss lifting the evacuation order, it never presented the survey results, nor did it even refer to the existence of the data.
The government only presented an outline of the results to the three municipalities earlier in April.
Asked to disclose the findings, the government released the survey results to The Asahi Shimbun and posted the midterm report on the website of the industry ministry.
The working team said it planned to reveal the survey’s findings and analysis of the data on April 18 after fine-tuning its final report. But the team changed its mind because The Asahi Shimbun’s request to disclose the findings made it realize that public interest in the survey was greater than expected.

I am sending you a copy of the article which appeared in the Sunday Mirror this week.
I would also like you to know that the Judge from the Upper Tier in Edinburgh has accepted my plea that my release medical document was a forgery, and he has ‘Directed’ that a fresh trial be heard where I will be given the chance to state my evidence. This will be the first time I have been permitted to tell the Courts of the true events that occurred during the British Nuclear tests at Christmas Island.
Besides the forged document, I have proof that other documents relating to dosage rates have been deliberately concealed.
I will let you know what happens.

Fukushima residents cleared to return home amid ongoing contamination fears
By Euan McKirdy, CNN
April 1, 2014 — Updated 1012 GMT (1812 HKT)
Families are cleared to return to a district of Tamura City in Fukushima prefecture — but is it worth the risk?
CNN) — Hundreds of residents of an area contaminated by a catastrophic reactor meltdown at a nuclear plant in northeastern Japan have been allowed to return home three years after the disaster.
An evacuation order, declared in the aftermath of a devastating tsunami that crippled the Fukushima-Daiichi nuclear plant in March, 2011, was lifted at midnight on Monday from the Miyakoji district of Tamura city in Fukushima Prefecture.
Residents of the town, who have been in limbo ever since, are now free to re-inhabit their homes following decontamination work in the area.

The Tohoku earthquake and subsequent tsunami off Japan’s northeastern coast led to the worst nuclear disaster since Chernobyl in 1986. Three reactors melted down, with the resulting radiation fallout forcing nearly 140,000 people from their homes.
Around 138,000 Fukushima residents remain in temporary accommodation, with a number of cities, towns and villages reduced to ghost towns due to continued high levels of radiation.
“We are doing as much as possible (to allow) the other residents can come home. We are strengthening support towards the residents (and) strengthening the decommissioning work,” a TEPCO spokesperson told CNN.
Monday’s lifting of the exclusion order is the first time an area this close to the site has been cleared. Miyakoji is 12 miles (20 kilometers) from the plant, on the edge of the initial exclusion zone.
Prior to the lifting of the order, some Fukushima residents were allowed to stay overnight in their homes, subject to registration. All restrictions on their movements have now been lifted within the cleared district.
355 residents — out of a total 116 households — are now free to return to their homes in Miyakoji permanently. The city of Tamura is one of eleven settlements in Fukushima that are still subject to evacuation orders.
However, concerns remain about background radiation levels and uncertainty surrounding the safety of the area, especially given past concerns about the reporting of radiation levels in the area by Fukushima’s operator, Tokyo Electric Power Company (TEPCO). Last month, Miyakoji residents were told at a community meeting that radiation contamination levels had lowered sufficiently to enable their return to the area — though some voiced concern over existing radiation levels despite decontamination efforts around some communities.
“Yes, I am a bit worried. But it’s my land, my house, so I am feel safer and more at home here,” one resident told broadcaster NHK.
Areas are declared suitable for habitation if residents are exposed to a maximum of 20 millisieverts of radiation per year. Officials have said they would like to get radiation exposure down to one millisievert a year.
The containment effort at the wrecked Fukushima plant has been beset by problems, with regular reports of leaks of contaminated material. Earlier this year, an estimated 100 metric tons of highly contaminated water flowed over a barrier around a containment tank and is being absorbed into the ground, TEPCO said in a statement — though it denied there was any leakage into the nearby Pacific Ocean.

Seen from an altitude of 13,000 meters at night, the crippled Fukushima No. 1 nuclear power plant shone brightly in a sea of darkness amid the loneliness of the evacuation zone.
The Asahi Shimbun flew its Asuka airplane over the municipalities of Fukushima Prefecture on Feb. 18. The plant was clearly visible because work to deal with the rising volume of contaminated water and to decommission reactors was actively ongoing, even at night.
In stark contrast, near-complete darkness enveloped areas designated as difficult-to-return zones for residents surrounding the plant.
The city of Iwaki in the prefecture and the bright glow of central Tokyo, once the main recipient of electricity generated from the plant, could also be glimpsed from the plane.
NOTE from Nelson
All these years, Tokyo’s electricity came in parts from Fukushima. Yet so many people and businesses have switched the ON button full blast ever since, not giving a single thought about what is happening to Fukushima. The contrast seen in terms of power generated electricity between Tokyo (top left of the picture) and anywhere west of Daiichi is revealing to say the least.
HEY TOKYO … Aren’t you suppose to save some energy after 311 ???

Japanese gov’t conceals high radiation data in Fukushima region from public
The Japanese government has postponed releasing the results of its latest measurement of radiation in three municipalities of the Fukushima region. The reason is the results are higher than expected, an unnamed source said in an interview with the Mainichi newspaper.
The matter is that the three municipalities in question currently have an active evacuation order, which might be lifted soon, and the government supports the lifting. That is why the Cabinet Office team decided to withhold the data as it might discourage residents from going back.
The recent measurements were significantly higher than expected: the levels were at 2.6 to 6.6 millisieverts a day, while expectations were at 1 to 2 millisieverts. The Japan Atomic Energy Agency and National Institute of Radiological Science decided to recalculate the results basing on an assumption that people would spend shorter periods outdoors than it is usually assumed in these cases (six hours instead of eight). The new results were submitted to the Cabinet Office team, and they plan to announce them later this month.
Atsuo Tamura from the Cabinet Office team has confirmed the recalculation and unreleased documents, but denied any attempts to conceal anything. But a professor of radiation and hygiene from the Dokkyo Medical University, Shinzo Kimura, has another opinion: “The assumption of eight hours a day outside and 16 hours inside is commonly used, and it is strange to change it. I can’t see it as anything but them fiddling with the numbers to make them come out as they wanted.”

“The incidence of thyroid cancer in children increased dramatically in the territories affected by the Chernobyl nuclear accident; this increase is probably attributable to (131)I and other short-lived isotopes of iodine released into the environment. There was a broad range of latency periods in children who developed thyroid cancer; some periods were less than 5 years.”

Fukushima 3 Years After: Thyroid Cancer Cases Among Children Rising by By Esther Tanquintic-Misa | March 10, 2014 3:12 PM EST
Cases of thyroid cancer among children residing in Fukushima have grown steadily since the disastrous March 2011 incident. Citizens have all but lost hope and confidence in their government. And three years after, no one has been made accountable for the supposed worst nuclear disaster since the 1986 Chernobyl.
To say that Fukushima’s children have been robbed of their childhood and right to play and explore the outside world is an understatement….Doctors have seen a rising number in the cases thyroid cancer in children and young adults in Fukushima. In February, the cases of thyroid cancer in individuals aged between 18 and below jumped to 75, where 33 were confirmed to have cancer.
On Sunday, thousands joined anti-nuclear protests to signify their loss of trust against the government as the latter moves to reignite the country’s 50 idled nuclear reactors….So far, 254,000 out of 375,000 Fukushima children have been tested for possible cancer ailments and will continue to be screened in their entire lifetime…”

March 11 marks the third anniversary of the earthquake and tsunami that devastated Japan’s Fukushima Daiichi nuclear power plant. In Koriyama, a short drive from the crippled Fukushima nuclear plant, the city recommended shortly after the disaster that children up to two years old not spend more than 15 minutes outside each day. Those aged 3 to 5 should limit their outdoor time to 30 minutes or less. The limits were lifted last year, but many kindergartens and nursery schools continue to obey them even now in line with the wishes of worried parents. An annual survey by the Fukushima prefecture Board of Education found that children in Fukushima weighed more than the national average in virtually every age group. The cause seems to be a lack of exercise and outdoor activity. Picture taken March 1, 2014. REUTERS/Toru Hanai”
