Radioactive Cesium (Cs*) on granular particles were detected using autoradiography, Germanium detector and energy dispersive X-ray spectrometry. The granular particle was included in the suspension of the rainwater tank, which was collected 20 months after the explosion of the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) triggered by the earthquake and following Tsunami on 11 March 2011. The particles are a compound of the silicon oxide and compound of the silicon oxide with Aluminum and Magnesium, respectively. Particle shape was not round but roughly granular with a size of 20μm. The particles are included at the rainwater tank at Ohkuma near FDNPP. The Cs*granular particles are proven to originate to the FDNPP investigating the ratio of Cs137 and Cs134
