Extraordinarily high level of radiation in Tokyo
An extraordinarily high level of radiation was detected in one spot in a central Tokyo residential district Thursday, prompting the local government to cordon off the small area, local officials said.
Radiation levels were higher in Tokyo’s Setagaya ward than in the evacuation area around the badly damaged Fukushima Daiichi nuclear plant, according to ward Mayor Nobuto Hosaka.
“We are shocked to see such high radiation level was detected in our neighborhood,” Hosaka told reporters.
But the tsunami-struck Fukushima plant may not be the source of the radiation, Hosaka said later on state television. Officials searching for the cause found “glass bottles in a cardboard box” in the basement of a house in the neighborhood which sent radiation detectors off the charts.
The Tokyo scare comes a day after officials in Yokohama, Japan’s second largest city, 155 miles (250 kilometers) from the Fukushima No. 1 nuclear plant, investigated soil samples after a radioactive substance was found in sediment atop an apartment building, according to news reports.
The discovery raised concerns that leaked radiation from three Fukushima reactors that suffered meltdowns after the March earthquake and tsunami may be more widespread than thought.
