TOKYO: Forty-five per cent of children tested in the region around Japan’s stricken nuclear plant were found to have traces of radioactive elements in their thyroid glands, an official said Thursday.
The official said that the iodine concentrations – found in tests that the government carried out about five months ago in Fukushima prefecture – were not considered alarming in terms of their health impact.
“The government’s official position is that none of the children showed radiation levels that would be problematic,” he told AFP.
The government’s nuclear accident taskforce tested 1,149 children aged up to 15 about two weeks after the March 11 earthquake and tsunami triggered meltdowns, blasts and fires at the Fukushima plant.
Radioactive iodine tends to gather in the thyroid glands of minors in particular, increasing the risk of developing cancer later in life.
Of the valid test results collected for 1,080 children, 482 or 44.6 per cent were confirmed to have some level of radioactive contamination in their thyroid glands, the government official told AFP.
The official, who spoke on condition of anonymity, said none of the children suffered contamination beyond the equivalent of 0.2 microsieverts (mSv) per hour, the standard set by Japan’s Nuclear Safety Commission.
“Only one child showed a contamination level of 0.1 mSv per hour, the highest of the group,” the official said without giving the child’s sex or age.
