The objective was to develop a method to measure the decontamination factor of FPs (aerosols) as they rise in sodium. We conducted measurement experiments with a particle counter using water, iron oxide (Fe3O4), and nitrogen gas. We were able to observe the change in the measured values depending on the particle size and water depth.
