Highest Fallout Levels in Tokyo Since May 2011

According to Tokyo Metropolitan Institute of Public Health, the fallout level (Cs-134/137) in Tokyo was the highest reading this March since May of 2011. (64 Bq/m2)

It was increasing since this February. The reason is not known.

By way of comparison, the European Union's limit for drinking water is 10 becquerels per liter.

Conversion Becquerel/Sievert and Sievert/Becquerel
1 Bq = 0.013 microsievert

ODA, Chiba — The municipal government here independently set a 1.0 millisievert maximum annual radiation dose for children [...] The new maximum dose breaks down to an hourly dose of 0.19 microsieverts, presupposing that a child spends eight hours a day outside. [...] Parts of the playground, where radiation of 0.25 microsieverts per hour has been detected, have been declared off-limits, while staff and children at the school must wear hats and wash their hands and gargle regularly.

Since they continually have earthquakes I am surprised the whole are has not blown up or dropped into the sea!

Since they have built their infrastructure with the instability of the area in mind, and made engineering designs to prevent wide-spread failure, I'm surprised more people don't have faith in Japanese infrastructure, and the people behind it...

The company operating the disaster-hit Fukushima Daiichi nuclear power plant (NPP) in northern Japan warned about the possibility of radioactive water leak, the Kyodo news agency reported on Friday. The Tokyo Electric Power Co. (TEPCO) said that “contaminated water may have leaked into soil from one of the seven underground reservoir tanks,” the agency reported. Radioactive substances have been detected in the water that accumulated outside the tank, covered by three layers of waterproof sheets. The exact volume of leak is unknown, but radiation levels in the water stand at about 6,000 Becquerel per cubic centimeter. Earlier on Friday, the company reported that a cooling system of the Unit Three spent atomic fuel storage facility temporarily failed at approximately 5:30 a.m. GMT, but the problem was fixed in about three hours. Three similar incidents were reported at spent fuel facilities at the plant’s units One, Three and Four last Month.

Yap ..

Some info here about one more very dangerous and vulnerable nuclear power plant in world or let me say most vulnerable In U.S.

Sorry B. You don't build Nuclear power plants on active fault lines, near oceans. You're just asking for the inevitable to happen, regardless on how "safe" the builders think its going to be.

According to Ministry of Health, Labour and Welfare, 210 Bq/Kg of Cs-134/137 was measured from edible wild plants ( Acanthopanax sciadophylloides) in Tochigi. This is the double amount of the safety limit.

Sampling date : 4/22/2013
Cs-134 : 72.3 Bq/Kg
Cs-137 : 135 Bq/Kg
Status : Not distributed

The sampling location is 102 km from Fukushima nuclear plant.
