Extreme levels of radiation have been detected in soil within 40 kilometers of the quake-stricken Fukushima No. 1 nuclear power plant, the science ministry said.
The finding emerged in a map published Aug. 29 that for the first time shows contamination levels of areas within a 100-km radius of the plant.
One location in the town of Okuma had the highest value at about 30 million becquerels of cesium of all types per square meter.
About 8 percent of the measured areas recorded more than 555,000 becquerels, the figure that required forcible relocation by residents in the 1986 Chernobyl nuclear incident.
