Some of the smallest children in Koriyama, a short drive from the crippled Fukushima Dai-ichi nuclear power plant, barely know what it is like to play outside — fear of radiation has kept them indoors for much of their short lives.
Though the strict safety limits for outdoor activity set after multiple meltdowns at the plant in 2011 have now been eased, parental worries and ingrained habit mean many children still stay inside.
And the impact is now starting to show, with children experiencing falling strength, lack of coordination — some cannot even ride a bicycle — and emotional issues like shorter tempers, officials and educators say.
“There are children who are very fearful. They ask before they eat anything: ‘Does this have radiation in it?’ and we have to tell them it’s OK to eat,” said Mitsuhiro Hiraguri, director of the Emporium Kindergarten in Koriyama, about 55km west of the Fukushima plant. “But some really, really want to play outside. They say they want to play in the sandbox and make mud pies. We have to tell them no, I’m sorry. Play in the sandbox inside instead.”
Following the 2011 quake and tsunami, a series of explosions and meltdowns caused the world’s worst nuclear accident in 25 years, spewing radiation over a swathe of Fukushima, an agricultural area long known for its rice, beef and peaches.
A 30km radius around the plant was declared a no-go zone, forcing about 160,000 people from homes where some had lived for generations. Other areas, where the radiation was not so critically high, took steps such as replacing the earth in parks and school playgrounds, decontaminating public spaces like sidewalks and limiting children’s outdoor play time.
‘AVOID OUTSIDE AIR’
In Koriyama, the city recommended shortly after the disaster that children up to two years old not spend more than 15 minutes outside each day. Those aged three to five should limit their outdoor time to 30 minutes or less.
These limits were lifted in October last year, but many kindergartens and nursery schools continue to adhere to the limits, in line with the wishes of worried parents.
One mother at an indoor Koriyama playground was overheard telling her child: “Try to avoid touching the outside air.”
Even three-year-olds know the word “radiation.”
Though thyroid cancer in children was linked to the 1986 Chernobyl nuclear accident, the UN said in May last year that cancer rates were not expected to rise after Fukushima.
Radiation levels around the Emporium Kindergarten in Koriyama were now down to between 0.12 and 0.14 microsieverts per hour, from between 3.1 and 3.7 right after the quake, Hiraguri said.
This works out to be lower than Japan’s safety level of 1,000 microsieverts a year, but levels can vary widely and at random, keeping many parents nervous about any outdoor play.
“I try to keep from going out and from opening the window,” said 34-year-old Ayumi Kaneta, who has three sons. “I buy food from areas away from Fukushima. This is our normal life now.”
CHILD STRESS ON RISE
However, this lack of outdoor play is having a detrimental affect on Koriyama’s children, both physical and mentally.
“Compared with before the disaster, you can certainly see a fall in the results of physical strength and ability tests — things like grip strength, running and throwing balls,” Koriyama City Government official Toshiaki Yabe said.
