Misao Fujita, a doctor who performs thyroid scans at a clinic in Iwaki, about 30 miles south of the nuclear plant, says a connection between the cancers and radiation exposure cannot be ruled out and the screening effect is no reason to disregard the examinations.
“What we do know is that after Chernobyl, many children developed thyroid cancer, and if you take that into account and consider the high risk that Fukushima children were exposed to radiation then I think we should carry out such tests,” Dr Fujita says, adding that thyroid cancer normally occurs in one in one million children.

The issue of the one million tons of contaminated water being stored at the stricken nuclear plant is another worry for residents.
After receiving assurances from Fukushima plant operator Tokyo Electric Power Company (TEPCO ) that the water had been successfully treated and stripped of all but one radioactive material, tritium, the government announced in 2017 it would start releasing the water into the ocean, despite protests, especially from local fisheries.
TEPCO released convoluted data to demonstrate the water’s safety, but was forced to backtrack last September when further tests showed the sums didn’t add up and 80 per cent of the water was in fact up to 20,000 times higher than the official safe threshold. Furthermore, it contained harmful radionuclides such as iodine, caesium and strontium.
However, a number of proposals to strip tritium from the water were submitted to the same task force by nuclear companies, with estimated costs ranging from US$2 billion to $180 billion, depending on the technology used. All of those proposals were dismissed as being impracticable.
“The reality is there is no end to the water crisis at Fukushima, a crisis compounded by poor decision-making by both TEPCO and the government,” says Mr Burnie.
Among more pressing issues, Mr Burnie says, is 400,000 cubic meters of sludge being stored within the Fukushima plant grounds that contains high concentrations of strontium – known as a “bone-seeker” because, if introduced into the body, it can accumulate in the bones in the same way as calcium does.
With the plant still generating waste, this sludge is expected to nearly double over the next 10 years, he adds.
Strontium releases into the environment from the plant were relatively small following the 2011 disaster, but significantly greater 30 months later, when in 2013 a large strontium-laced plume contaminated land as far away as Minamisoma – a city about 20 km from the plant, Mr Burnie says.
Such an event could re-occur, he says.“Is it a good idea to lift the evacuation orders? Absolutely not. The public are right to be concerned about the possibility of further offsite releases.”
Meanwhile tests on samples of soil – which has no official safe threshold in Japan – have also revealed high levels of radiation in the area, she adds.
Namie’s Obori district, about six miles northwest of the nuclear plant and within the difficult-to-return-zone, is one place where soil radiation levels remain high. In woodland backing the pretty hamlet, which is famed for its pottery but has slowly surrendered to nature, the Telegraph recorded up to 127 µSv per hour – over 350 times the IAEA’s safe threshold.

The revelation "completely destroyed the premise for discussions," the Mainichi source said, and public worries about releasing the water into the environment prompted the government to reconsider.
The water volume continues to increase due to ground water flowing into the fractured reactor buildings, and the need to keep pumping more water into the shattered reactor cores to cool the nuclear fuel debris inside.
Just after the March 2011 triple-meltdown at the plant triggered by the Great East Japan Earthquake and tsunami, the amount of groundwater flowing into the reactor buildings was around 400 tons daily.
A subterranean ice wall and other measures have cut this by about half, but eliminating it entirely is impossible.
It is expected to take until 2051 to finish decommissioning the Fukushima Daiichi plant, including processing the contaminated water.
