A group of researchers led by Hiroshima University professor Satoshi Tashiro tested 1,149 children in the prefecture for radiation in their thyroid glands in March following the accident at the Fukushima Daiichi nuclear plant. Radioactive iodine was detected in about half of the children.
Tashiro says radiation in thyroid glands exceeding 100 millisieverts poses a threat to humans, but that the highest level in the survey was 35 millisieverts.
Tashiro says based on the result, it is unlikely that thyroid cancer will increase in the future, but that health checks must continue to prepare for any eventuality.

U.S. Government Poisons Americans in "Test"
The "Green Run" was a secret US Government release of radioactive materials on December 2–3, 1949, at the Hanford Site plutonium production facility. Radioisotopes released at that time were supposed to be detected by US Air Force reconnaissance.
Freedom of Information Act (FOIA) requests to the US government have revealed some of the details of the experiment.
Sources cite 5,500 to 12,000 curies (200 to 440 TBq) of iodine-131 released.
There are some indications contained in the documents released by the FOIA requests that many other tests were conducted, although the Green Run was a particularly large test. Evidence suggest that [color=limegreen]filters to remove the iodine were disabled during the Green Run.
The most significant challenge at Hanford is stabilizing the 53 million U.S. gallons of high-level radioactive waste stored in 177 underground tanks.
About a third of these tanks have leaked waste into the soil and groundwater. As of 2008, most of the liquid waste has been transferred to more secure double-shelled tanks; however, 2.8 million U.S. gallons of liquid waste, together with 27 million U.S. gallons of salt cake and sludge, remains in the single-shelled tanks.
That waste was originally scheduled to be removed by 2018.
The revised deadline is 2040.
Data generated by the U.S. Department of Energy (DOE) shows that [color=limegreen]the site is so porous that the mountain itself contributes almost nothing to waste isolation.
Instead, DOE relies almost completely on a system of engineering fixes, the most outlandish of which are waste disposal containers that must last for at least one million years combined with approximately sixty miles of tunnels lined with thousands of titanium drip shields that DOE does not plan to install for 100 to 300 years or more.
