This comprehensive survey report by Greenpeace Japan in the towns of Iitate and Namie in Fukushima prefecture, including the exclusion zone, revealed radiation levels up to 100 times higher than the international limit for public exposure. The high radiation levels in these areas pose a significant risk to returning evacuees until at least the 2050’s and well into next century.

Greenpeace Japan conducted the investigations in September and October in 2017, measuring tens of thousands of data points around homes, forests, roads and farmland in the open areas of Namie and Iitate, as well as inside the closed Namie exclusion zone. The government plans to open up small areas of the exclusion zone, including Obori and Tsushima, for human habitation in 2023. The survey shows the decontamination program to be ineffective, combined with a region that is 70-80% mountainous forest which cannot be decontaminated. The findings come just two weeks ahead of a critical decision at the United Nations Human Rights Council (UNHRC) review on Japan’s human rights record and commitments to evacuees from the nuclear disaster.
