Researchers have detected a radiation hotspot in Japan's capital of Tokyo months after a nuclear disaster in the earthquake-prone country.
Radiation of up to 3.35 microsieverts per hour was recorded Thursday at a height of 1 meter along a street in the west of the capital - 220 kilometers (136 miles) from the site of the troubled nuclear reactors in the Fukushima nuclear power plant - much higher than previously reported levels, Kyodo News reported.
Since a 9.0-magnitude earthquake and a devastating tsunami on March 11, the Daiichi Fukushima nuclear plant has been leaking radiation into the air, soil.
The quake triggered a nuclear crisis by knocking out power to cooling systems at the nuclear power plant on Japan's northeast coast.
The number of the dead and missing from the quake and tsunami stands at over 28,000, according to the Japanese National Police Agency.
