Citizen Scientists: Many Fukushima residents don’t trust the government’s reports of radiation levels because official communications during the crisis were confusing, irregular, and sometimes inaccurate. Citizen science groups have therefore started up to conduct their own radiation monitoring.

Their radiation detectors are strapped to their car, and the GPS-tagged data will be uploaded to online maps.
