The Cs atoms (IMAGE) University of Helsinki Caption Figure 1. (Left) A structure model of pollucite and a simulated HAADF-STEM image using MacTempas. (Right) A high resolution HAADF-STEM image of iron-rich pollucite in the CsMPs. The Cs atoms in the image appear as bright spots (circled in the image). Approximately half of the Cs atoms in the structure are radioactive. Radioactive Cs atoms have not been imaged before from environmental samples. Credit Kanako Miyazaki et. al.
