The Decrease Demonstration Experiment of the Radiation of the Nuclear Accident The asphalt surface of the about 4km spot from the Fukushima 1st Nuclear Power Plant in Okuma-Town “The radioactive-ray-contamination area density BECQUEREL“ “The spatial radiation dose SIEVERT” Radiation level decrease in BECQUEREL & SIEVERT effect by Adsorption Miracle Sand (Ryukyu limestone) An experiment purpose:Return to the normal level before the nuclear plant accident 0.00 Bq/cm2 0.04 µSv/h

The demonstration experiment on the increase of the radiation value by the accumulation surplus soil、 and the decrease of the radiation value by the Ryukyu limestone scattering The discovery of the coefficient "7" of the 　fluctuation of the radiation value　 3km spot from Fukushima first Nuclear Power Plant “The radioactive-ray-contamination area density BECQUEREL“ “The spatial radiation dose SIEVERT”

Radiation level increase experiment by the accumulation remaining soil Purpose: In a process of the accumulation remaining soil , the risk that a radiation level increases occurs. It shows that by this experiment. In accumulation of the 60cm square soil by this experiment, there is increase of approximately 2 times. In the case of large quantities,it increases more
