Japan self-defense force member in plastic body suit and mask is under the operation of decontaminating the land in Iitate-village, Fukushima prefecture. The radiation leakage from Fukushima Daiichi Nuclear Power Plant contaminated the soil after the magnitude 9.0 earthquake and tsunami. While the efficient measure is still being identified, the member, with a flat screwdriver, has to resort to a simple method that digs the soil in stone pavement and sweeps with a broom. The decontamination process, requiring enormous amount of time and costs, have yet to reach the solution.
