The spent absorbent was stably solidified by using metakaolin as a hydraulic solidifier. The weight of the final radioactive waste was estimated to be less than 1/1000 of the original one.環境放射能除染学会The Society for Remediation of Radioactive Contamination in the Environment2018-06jpnjournal articleVoRhttp://hdl.handle.net/2115/78806400216213942187-8382環境放射能除染学会誌Journal of the Society for Remediation of Radioactive Contamination in the Environment627380https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/78806/1/2018SRRCEV6N2-P73-80_Ichikawa.pdfapplication/pdf1.03 MB2018-06
