Informational power to the people: Safecast volunteers monitor Fukushima radiation

 

NGO Safecast co-founder Pieter Franken explains to schoolgirls how to assemble a Geiger counter kit in their classroom in Koriyama City, Fukushima Prefecture.

The machine is sending data to Safecast, an NGO born after the March 2011 Fukushima nuclear disaster that says it has now built the world’s largest radiation dataset, thanks to the efforts of citizen scientists like Seirinji’s priest Sadamaru Okano.

Like many, Okano lost faith in the government after the nuclear meltdown seven years ago.

“The government didn’t tell us the truth, they didn’t tell us the true measures,” he said.

Okano was in a better position than most to doubt the government line, having developed an amateur interest in nuclear technology 20 years earlier after the Chernobyl disaster. To the bemusement of friends and family, he started measuring local radiation levels in 2007.

“The readings were so high, 50 times higher than natural radiation,” he said of the post-disaster data. “I was amazed. The news told us there was nothing, the administration was telling us there was nothing to worry about.”

That dearth of trustworthy information was the genesis of Safecast, said co-founder Pieter Franken, who was in Tokyo with his family when disaster hit. Franken and friends had the idea of gathering data by attaching Geiger counters to cars and driving around.

“Like how Google does Street View, we could do something for radiation in the same way,” he said. “The only problem was that the system to do that didn’t exist and the only way to solve that problem was to go and build it ourselves. So that’s what we did.”

Within a week, the group had a prototype and got readings that suggested the 20-kilometer exclusion zone declared around the Fukushima plant had no basis in the data, Franken said.

“Evacuees were sent from areas with lower radiation to areas with higher radiation” in some cases, he said.

The zone was eventually redrawn, but for many local residents it was too late to restore trust in the government.

Okano evacuated his mother, wife and son while he stayed with his flock.

A year later, based on his own readings and after decontamination efforts, he brought them back. He learned about Safecast’s efforts and in 2013 installed one of their static counters on his temple.

“I told them: ‘We are measuring the radiation on a daily basis… so if you access the (Safecast) website you can choose (if you think) it’s safe or not’.”

Norio Watanabe has been a Safecast volunteer since 2011. In the days after the disaster evacuees flocked to Koriyama, which was outside the evacuation zone. He assumed his town was safe.

He sent his children away, but stayed behind to look after his mother, a decision he believes may have contributed to his 2015 diagnosis of thyroid cancer.

“As a scientist, I think the chance that it was caused by the Fukushima accident might be 50-50, but in my heart, I think it was likely the cause,” he said.

His thyroid was removed and is now healthy, but Watanabe worries about his students, who he fears “will carry risk with them for the rest of their lives.”

“If there are no people like me who continue to monitor the levels, it will be forgotten.”

Safecast now has around 3,000 devices worldwide and data from 90 countries. Its counters come as a kit that volunteers can buy through third parties and assemble at home.
