Radiation levels at municipalities around the quake-damaged nuclear power plant in Fukushima Prefecture continue to be higher than normal. But authorities say the detected levels pose no harm to human health.
As of 9 AM Thursday, at Fukushima City, 65 kilometers northwest of the Fukushima Daiichi plant, radiation level was 13.9 microsieverts per hour. This is more than 340 times the usual background level.
At Koriyama City located west of the plant, the reading was 2.71 microseiverts, 45 times the normal level.
South of the plant, in Iwaki City, radiation levels were as high as 20 times the usual level at 1.25 microseiverts.
At the Onagawa nuclear power plant 120 kilometers northeast of the Fukushima plant, radiation levels measured 3.2 microseiverts, 32 times the usual amount.
In Kitaibaraki City south of the Fukushima plant, radiation found to be 1.19 microseiverts, 23 times the normal figure.
But health authorities say one-hour of exposure to radiation at any of the observed levels would range between one 500th to one 40th of the amount of radiation the body would receive in a single stomach X-ray.
