The development of methods for the removal of radioactive substances from irrigation water is crucial for paddy farming. Removing radioactive substances from irrigation water at the inlet of a paddy field by absorption and filtering media such as chaff and zeolite was tried without knowing the effectiveness.\n Thus, two kinds of experiments were conducted to confirm the removal effects of absorption and/or filtering by some media. Three kinds of materials, rice husk, carbonized rice husk, and zeolite, were compared in the field study while these materials and a fourth, a Prussian blue coated nonwoven textile, were compared in the laboratory test. The results were as follows.\ni) High adsorption ratios of dissolved Cs were obtained using zeolite and Prussian blue coated nonwoven textile, and the adsorption function was also confirmed in rice husk and carbonized rice husk in simple batch tests in the laboratory.\nii) The removal of radioactive Cs was most effective in the order of zeolite, rice husk, and carbonized rice husk in the field tests.\niii) The radioactive Cs concentration in materials rose by decreasing the amount with which the mesh bag was filled with rice husk or carbonized rice husk.\niv) The removal efficiency of radioactive Cs was decreased by increasing the water flow-through when the same materials were used.\nv) The appropriate amounts of materials for the effective removal of radioactive Cs suitable for the size of the mesh bag to be used could be determined.\nvi) The concentrations of radioactive Cs transported with irrigation water and contained in the accumulating precipitate were high in the study area.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_12_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/0002001673","subitem_identifier_reg_type":"JaLC"}]},"item_12_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人
