About 45 per cent of children in Fukushima prefecture experienced thyroid exposure to radiation after the nuclear power there was damaged in March, officials said Tuesday.
But the results were not high enough to require further examination, the Nuclear Safety Commission said.
In late March, local and central governments carried out the survey on 1,080 children under the age of 15 in areas near the damaged Fukushima Daiichi Nuclear Power Station after the crisis.
The plant has been leaking radioactive substances since it was hit by a magnitude-9 earthquake and resulting tsunami on March 11.
Among children who tested positive for thyroid exposure, the amounts measured 0.04 microsieverts per hour or less in most cases, while the largest exposure was 0.1 microsieverts per hour, equivalent to a yearly dose of 50 millisieverts for a one-year-old baby, Kyodo News reported.
