We have found radiation at levels high enough to raise health concerns for the people who continue to live daily with this contamination. We have also shown that the authorities have consistently underestimated both the risks and extent of radioactive contamination. Based on our results we called for a significant extension to the evacuation area, which was later implemented. We advised that until decontamination was completed, children should be held back from their schools to avoid high radiation levels. We have also found that official monitoring stations systematically underestimate the radiation risks for the population.
Our analysis of the threats to public health have given residents an alternative to the often contradictory information released by Japan’s authorities since the Fukushima disaster began.
The teams are made up of Greenpeace radiation experts who have been trained in radiation monitoring and the use of sophisticated measuring devices.
Locations and details of radiation levels to date are shown on the maps below.
