Volunteers Crowdsource Radiation Monitoring to Map Potential Risk on Every Street in Japan

Volunteers Crowdsource Radiation Monitoring to Map Potential Risk on Every Street in Japan

"Safecast is a network of volunteers who came together to map radiation levels throughout Japan after the Fukushima Diiachi nuclear power plant disaster in 2011. They soon realized radiation readings varied widely, with some areas close to the disaster facing light contamination, depending on wind and geography, while others much further away showed higher readings. Safecast volunteers use Geiger counters and open-source software to measure the radiation, and then post the data online for anyone to access."
