The New York Times reported yestderday:
Takeo Hayashida signed on with a citizens’ group to test for radiation near his son’s baseball field in Tokyo after government officials told him they had no plans to check for fallout from the devastated Fukushima Daiichi nuclear plant. Like Japan’s central government, local officials said there was nothing to fear in the capital, 160 miles from the disaster zone.
Then came the test result: the level of radioactive cesium in a patch of dirt just yards from where his 11-year-old son, Koshiro, played baseball was equal to those in some contaminated areas around Chernobyl.
The patch of ground was one of more than 20 spots in and around the nation’s capital that the citizens’ group, and the respected nuclear research center they worked with, found were contaminated with potentially harmful levels of radioactive cesium.
Some of the sampled areas were extremely hot:
…the sample that Mr. Hayashida collected under shrubs near his neighborhood baseball field in the Edogawa ward measured nearly 138,000 becquerels per square meter of radioactive cesium 137, which can damage cells and lead to an increased risk of cancer.
Of the 132 areas tested, 22 were above 37,000 becquerels per square meter, the level at which zones were considered contaminated at Chernobyl.
The Times also reported:
The most contaminated spot in the Radiation Defense survey, near a church, was well above the level of the 1.5 million becquerels per square meter that required mandatory resettlement at Chernobyl. The level is so much higher than other results in the study that it raises the possibility of testing error, but micro hot spots are not unheard of after nuclear disasters.
The latest studies confirm other findings:
Last month, a local government in a Tokyo ward found a pile of composted leaves at a school that measured 849 becquerels per kilogram of cesium 137, over two times Japan’s legally permissible level for compost.
And on Wednesday, civilians who tested the roof of an apartment building in the nearby city of Yokohama — farther from Fukushima than Tokyo — found high quantities of radioactive strontium.
