Radiation values of radioactively-contaminated soil filled with Mizuho water measured immediately after a rite of Shinto practice(No.14 of the results table). (Putting another substance or to add a new Mizuho water, physical change has not been given).
Experimental result；Radioactive Cesium 2852.7Bq/kg
105.3 Bq/kg decreased from the experiment No.13, it means a decrease of 4%.
Radiation values of radioactively-contaminated soil filled with Mizuho
