The Silica coating technique has been developed at Choetsu Chemistry Research Co. Ltd. Within a shorter time after the TEPCO Daiichi Nuclear Plant Accident, decontamination method and shielding cloth were invented in order to protect Fukushima children from radiation. In the experiments to verify their applicability, the following facts were observed: depth of radioactive cesium was 1.5 cm in soil of school grand and shielding performance from the results on radiation transmission images measured at KURNS.
