Greenpeace radiation specialist Heinz Smital doing measuring outside an abandoned kindergarten in Shimo-Tsushima in the exclusion zone of Namie, Fukushima prefecture, Japan, which is closed for people to return to. Greenpeace radiation survey at a home nearby area showed levels ranging from averages of 1.3 microsieverts per hour to a maximum of 5 microsieverts per hour. However, the Japanese government plans to open a small area of Tsushima as early as 2023. The levels of radiation measured by Greenpeace in this highly contaminated area mean that it will be many decades and beyond the end of the century before radiation levels will even approach government targets.
