Radiation levels shot up in Tokyo and its vicinity Tuesday following the nuclear accident at the Fukushima No. 1 nuclear power plant in northeastern Japan that was triggered by last week’s massive earthquake and subsequent tsunami, local governments said.
But those levels did not pose immediate danger to human health, the Ministry of Education, Culture, Sports, Science and Technology said.
In Tokyo, small amounts of radioactive substances, such as iodine and cesium, were detected, the metropolitan government said.
In Ibaraki Prefecture, adjacent to Fukushima Prefecture where the troubled Fukushima No. 1 nuclear power plant is located, the amount of radiation at one stage reached 5 microsievert per hour, 100 times higher than usual, the Ibaraki prefectural government said.
In Kanagawa Prefecture, the radiation level shot up 10 times higher than usual.
