Eight months after a tsunami caused a nuclear accident in Japan, ordinary people are using new technology and the power of crowdsourcing to find radiation hotspots. NewsHour science correspondent Miles O’Brien reports from Japan.
Wherever they go, they draw a crowd, a curious, nervous, thankful crowd. In a restaurant parking lot in Nihonmatsu, about 60 kilometers from the nuclear plant, we met Hiroko Ouchi.
“I’m worried about my children and grandchildren,” she told us. “Thank you for measuring. Thank you for your hard work. The government doesn’t release the accurate figures of radiation.”
