Locations of monitoring stations A~G in the greater Kanto Region and radioactive particles isolated in this study. Coordinates and collection time of the filters are shown for each station. White dashed lines on the map indicate distance from the FDNPP. Eight CsMPs were isolated from these seven filters as displayed by SEM images around the map. They are nearly spherical in shape with a diameter of 1.3 μm (particle A1), 1.3 μm (B1), 1.4 μm (C1), 1.5 μm (D1), 1.2 μm (D2), 1.3 μm (E1), 0.9 μm (F1), and 1.8 μm (G1). The scale bars under the SEM images show a length of 1 μm
