Fukushima moms don lab coats to measure radiation in food, sand and soil — The Japan Times

At a laboratory an hour’s drive from the crippled Fukushima No. 1 nuclear plant, a woman wearing a white mask over her mouth presses bright red strawberries into a pot, ready to be measured for radiation contamination.

Six years after a massive earthquake off the Tohoku coast triggered tsunami that knocked out the plant’s cooling system, causing three reactor-core meltdowns, local mothers with no scientific background staff a laboratory that keeps track of radiation levels in food, water and soil.

As some women divide the samples between different bowls and handmade paper containers, others are logging onto computers to keep an eye on data — findings that will be published for the public to access.

The women on duty, wearing pastel-colored overalls, are paid a small salary to come in for a few hours each day, leaving them free to care for their children after school.

“In universities, data (are) handled by students, who have taken exams qualifying them to measure radiation. Here, it’s done by mothers working part time. It’s a crazy situation,” laughed Kaori Suzuki, director of Tarachine, the nonprofit organization that houses the mothers’ radiation lab.

“If (university professors) saw this I think they would be completely shocked by what they see.”

Tarachine was set up 60 km down the coast from the Fukushima plant, in the city of Iwaki. After the magnitude-9 quake struck on March 11, 2011, triggering mountainous tsunami, authorities declared a no-go zone around the plant.

Iwaki lay outside its 30 km radius, with lower radiation levels compared to the rest of Fukushima Prefecture.

But with public announcements advising locals to stay indoors in the aftermath of the worst nuclear calamity since Chernobyl, the “invisible enemy” of radiation has continued to worry the mothers working at the lab.

“As ordinary citizens we had no knowledge about radiation. All we knew was that it is frightening,” said Suzuki.

“We can’t see, smell or feel radiation levels. Given this invisibility, it was extremely difficult for us. How do we fight it? The only way is to measure it.”

To supplement readings by the central government and Tokyo Electric Power Company Holdings Inc., which manages the nuclear plant, Tarachine publishes its own findings every month.

With donations from the public that helped them buy equipment designed to measure food contamination, the mothers measure radioactive isotopes cesium-134 and-137, and collect data on gamma radiation, strontium-90 and tritium, all of which were released during the Fukushima disaster.

Strontium-90 gravitates toward the bones when absorbed by breathing it, drinking it in water, or eating it in food. It can remain for years, potentially causing bone cancer or leukemia.

Tritium goes directly into the soft tissues and organs of the human body. Although it is less harmful to humans who are exposed to small amounts every day, it could still be a hazard for children, scientists say.

The mothers say other parents trust the lab’s radioactivity readings in local food more than those from the government.

“This issue is part of everyday life for these mothers, so they have the capability to spot certain trends and various problems rather than just accumulating expert knowledge,” said Suzuki.

To handle potentially dangerous materials, the mothers have had to study for exams related to radiation and organic chemistry.

“At the beginning I was just completely clueless. It gave me so much of a headache, it was a completely different world to me,” said Fumiko Funemoto, a mother of two who measures strontium-90 at the lab.

“But you start to get the hang of it as you’re in this environment every day.”

As the lab only accepts items for testing from outside the exclusion zone, most results show comparatively low radiation levels.

But Suzuki said it was an important process and especially reassuring for the parents of young children. The women also measure radiation levels in sand from the beach, which has been out of bounds to their children.

“If the base is zero becquerels, and there is, say, 15 or 16 becquerels of cesium, that’s still higher than zero. That means there is slightly more risk,” Suzuki said.

“There are also times when you’re like, ‘Oh, I thought levels were going to be high there — but it’s actually OK.’ The importance lies in knowing what’s accurate, whether it’s high or low. Unless you know the levels, you can’t implement the appropriate measures.”

Since official screenings began following the meltdowns, 174 children in Fukushima Prefecture have been diagnosed with — or are suspected of having — thyroid cancer, according to figures from the prefecture.

Despite the International Atomic Energy Agency (IAEA) reporting in 2015 that an increase in thyroid cancer is unlikely, the mothers insist there is value in their work.

The first pictures from inside the nuclear plant were released by Tepco in January, announcing it may have found melted nuclear fuel below the damaged reactor 2 — one of three affected by the 2011 disaster.

“In general, the issue of nuclear power is not really talked about much these days,” Funemoto said. “It was talked about after the (meltdowns) for about a year or so, but today, conversations mentioning words like ‘radiation’ don’t happen anymore.”

However, she said “the reality is different.”

“The radiation isn’t going to go away. That’s why I’m doing this. So many places are still damaged. This idea that it’s safe and that we shouldn’t be anxious doesn’t really add up,” she said.

Ai Kimura, another mother, agreed. “My parents think I’m a bit paranoid. They keep saying, ‘It’s OK isn’t it?’ ” she said.

“But what if there’s a chance that in 10 or 20 years’ time, my own child gets thyroid cancer? And I could have done my bit to minimize the risks. My children are mine and I want to do whatever I can to protect them.” ”

Thousands protest ahead of Fukushima anniversary — St. Louis Post-Dispatch; Fukushima Anniversary: Voices from Japan — Nuclear Hotseat

1)  ” TOKYO • Banging on drums and waving “Sayonara nukes” signs, thousands of people rallied in a Tokyo park and marched to Parliament on Sunday to demand an end to nuclear power ahead of the third anniversary of the Fukushima disaster.

Participants at the demonstration, one of several planned across cities in Japan, said they would never forget the March 11, 2011, nuclear disaster, the worst since Chernobyl. The plant was damaged by a massive earthquake and then hit by a tsunami.

They also vowed to block a move by the government of Prime Minister Shinzo Abe to restart some of the 48 idled reactors and backpedal on the commitment by the previous government to aggressively reduce the nation’s reliance on nuclear power. Oil imports have soared since the disaster, hurting the economy. … ”
