Radiology experts from Greenpeace urged the government to revise their evacuation protocol Monday after they found high levels of radiation around the greater Fukushima area and in the region's fresh produce.
A team of radiologists and safety advisers of the nongovernmental organization said a survey conducted from April 4 through Sunday detected radiation levels of 4 microsieverts per hour at a playground in the city of Fukushima. That would translate into a potential annual exposure of 5 millisieverts, Greenpeace expert Rianne Teule said, explaining that the level was the threshold for evacuation at Chernobyl.
The group also said that all 11 samples of local vegetables from gardens and small farms within the prefecture contained radioactivity exceeding the legal limit of 2,000 becquerels per kilogram set by the farm ministry. For example, 152,340 becquerels were found in spinach from a small patch on the outskirts of the city of Fukushima, the group said.
