As a preliminary step to elucidate the adsorption behavior of Cs-containing aerosols on epoxy resin, we observed the change in properties of CsI aerosols at each humidity. Specifically, the microstructure of the particles at each humidity was captured by SEM, and the Cs concentration at that humidity was quantified by atomic absorption spectrometry. As a result, we confirmed the particle distribution according to the distance from the aerosol source and the change in properties of particles that aggregate at high humidity. We will investigate the interaction with epoxy resin based on the results of the properties obtained in this study.
