Fukushima Prefecture Radiation

It is simply unacceptable that the Japanese government is considering lifting evacuation zones.

Here are some relevant headlines.

Let us begin with Blogger Ex-SKF's report this morning

Ex-SKF: Radiation in Fukushima City Order of Magnitude Higher Than Official Numbers?

From someone in Japan posting a short post at this website of a TV program he just saw on July 24 morning (their time):

On TBS Television "Sunday Morning News". Radiation survey by Doshisha University and Kyoto Seika University of Fukushima City [in Fukushima Prefecture].

U-drain at an elementary school 56.9 microsieverts/hour; Fukushima Prefectural Government building 20.8 microsieverts/hour, Fukushima Railroad Station 2.4 to 22.4 microsieverts/hour. "Hot spot" everywhere. The Doshisha researcher was surprised to see these numbers. Does Fukushima City residents know about this?....

I live in central Tokyo and have been measuring the air etc., for some time. My dosimeter which is good quality usually reads about .08 up to .11 microsieverts per hour. This is about double the number/level that is printed in the Japan Times and other papers as the official government radiation level for Tokyo.

I measured the soil awhile back and it was about .2 which indicates a certain saturation of radioactivity, but the school grounds are not tested, and no one is demanding they are.

The lying is prevalent and very few people here actually care. It is amazing to behold.

Citizens Find Radiation Far From Fukushima Science 17 June 2011: Vol. 332 no. 6036 p. 1368 Dennis Normile

"Frustrated by a dearth of information on what happened to all of the radiological isotopes released from the ravaged Fukushima nuclear power plant, civic groups and individuals have been monitoring radiation on their own. Collectively, they have produced a worrisome picture of contamination throughout eastern Japan, with some hot spots surprisingly far from the crippled reactors.

“Authorities don't want to tell people about the real dose rates,” says Atsuhito Ennyu, a geochemist at Itochu Oil Exploration Co. in Tokyo who has spent most of his free time for the past 10 weeks taking radiation measurements and posting them on a Web site.

"The distrust extends to academia. On 13 June, 40 University of Tokyo faculty members petitioned the school to revise what they say is misleading information posted on its Web site regarding radiation at its Kashiwa, Chiba, campus. “University of Tokyo has a big impact on society; the information it disseminates should be accurate,” says Masaki Oshikawa, a physicist based in Kashiwa and one of the petition organizers...

...Local government officials later joined the act, ordering radiation checks of schoolyards and other public places and posting the results on their Web sites. An anonymous volunteer recently plotted the available 6300 data points on a map. And Yukio Hayakawa, a volcanologist at Gunma University, turned that plot into a radiation contour map.

It shows one wide belt of radiation reaching 225 kilometers south from the stricken reactors to Tokyo and another extending to the southwest. Within those belts are localized hot spots, including an oval that encloses northeast Tokyo and Kashiwa and neighboring cities in Chiba Prefecture.

Radiation in this zone is 0.4 microsieverts per hour, or about 3.5 millisieverts per year. That is a fraction of the radiation found throughout much of Fukushima Prefecture, which surrounds the nuclear power plant. But it is still 10 times background levels and even above the 1-millisievert-per-year limit for ordinary citizens set by Japanese law....


KINDERGARTEN FIGHTING RADIATION FROM FUKUSHIMA PLANTAnonymous. Jiji Press English News Service [Tokyo] 16 June 2011.

"Iwaki, Fukushima Pref., June 16 (Jiji Press)--About 45 kilometers away from the crippled Fukushima No. 1 nuclear power plant, a private kindergarten in this northeastern Japan city is fighting radiation.

"We protect our children ourselves," says the Satogaoka kindergarten, which voluntarily takes various steps including the compilation of a map showing radiation levels in the air within its premises.

Every day since May 9, kindergarten staff monitors air radiation levels at the playground and posts the results on a notice board. The radiation map covering some 50 locations such as points inside nursery rooms and near playground equipment is updated every few days.

No serious contamination has been confirmed so far, with the highest reading obtained in the kindergarten is around 0.7 microsievert per hour.


Chernobyl’s Evacuation Zone was 5 millisieverts a year. Japan has set their evacuation zone at an incredibly high 20 millisieverts per year
