要旨 For the decommissioning of the Fukushima-Daiichi Nuclear Power Station and for the safety assessment of concrete facilities for radioactive waste disposal, evaluation of cesium (Cs) transfer in concrete is essential. In this study, several factors affecting Cs transfer, such as Cs concentration, clay, and carbonation, are experimentally evaluated using autoradiography of radioisotope Cs-137 by imaging plate. For the evaluation, mortar specimens were immersed in CsCl solution. The concentration did not affect the transfer profiles for sound mortar. However, carbonation increased the Cs binding and retarded the transfer.
