A group of more than 10 mothers set up a citizen-led laboratory to monitor radiation levels in Fukushima communities only months after a massive earthquake and tsunami caused meltdowns at a nuclear power plant in the prefecture nine years ago.

Since the foundation of the institute on Nov. 13, 2011, it has been recording and disclosing radiation data on foodstuffs and soil it collected or were brought in by people from different parts of the prefecture, as well as seawater off the Fukushima No. 1 nuclear power plant.

"If the risks of nuclear power had been thoroughly verified by the previous generations, I think the disaster would not have happened," Kaori Suzuki, 54, an executive of Mothers' Radiation Lab Fukushima, based in Iwaki, said in a recent interview.
