[The Association for Citizens and Scientists Concerned About Internal Radiation Exposures] measured radiation levels about 10 meters away from each of the posts.
The group’s readings at those locations averaged 40-50 percent higher than the figures reported by the ministry at the posts themselves.
“We are afraid that the ministry might have thoroughly decontaminated areas immediately adjacent to the monitoring posts or tinkered with numbers in an attempt to get lower readings,” Katsuma Yagasaki, professor emeritus of physics at the University of Ryukyus, told a news conference in Tokyo.
