TOKYO, May 23 (Xinhua) -- Children living in Fukushima Prefecture in Japan are significantly more likely to suffer from thyroid cancer after the Fukushima nuclear disaster despite denial by Japanese authorities, according to recent reports.
The rate of children suffering from thyroid cancer in Fukushima Prefecture was as much as 20 to 50 times higher than the national average as of 2014, three years after the disaster, said Toshihide Tsuda, professor of environmental epidemiology at Okayama University.
More than 160 teenagers in Fukushima Prefecture had been diagnosed with thyroid cancer, including suspect cases, since the Fukushima Daiichi nuclear power plant was crippled by the monstrous quake-triggered tsunami in March 2011.
The number almost certainly increased with the passage of time, according to Tsuda's findings published in the electronic edition of the journal of the International Society for Environmental Epidemiology (ISEE) late last year.
On the fifth anniversary of the Fukushima nuclear crisis, the parents of the children thyroid cancer sufferers in Fukushima formed a mutual help group to demand the government provide convincing evidence that their children's sufferings were not related to the nuclear crisis.
The ISEE has sent a message to the Japanese government suggesting it to conduct detailed and continuous research on residents' health in Fukushima, but the government did not respond to the advice, Tsuda said.
The Fukushima prefectural government doubted the cases were related to the nuclear disaster and attributed the surge to "over diagnosis."
Some nuclear experts were surprised by the Japanese government's irresponsible and indifferent attitude.
Oleksiy Pasyuk, an expert on energy policy at the National Ecological Center of Ukraine, said that one of the main mistakes made by Japan in the aftermath of the accident was that the government had not stocked enough medicinal iodine tablets, which can prevent the absorption of radioactive material into the human body.
According to research by Fukushima University, about 3,500 trillion becquerels of radiative cesium-137 were discharged into the sea with toxic water since the disaster broke out and radiative material reached as far as the western coast of northern America.
Meanwhile, about 1,000 evacuees are still displaced and live in temporary housing camps due to the uncontrolled aftermath of the nuclear disaster.
