The synthesis of polymeric microspheres, combining organic and inorganic materials (hybrid beads), has a great industrial interest because these beads may have new properties that can be suitable for new applications. Varying the composition, the size or the structure of the components through an appropriate chemical route, the researcher can make the sphere that best fit his purpose. However, hybrid spheres's properties that can be useful for Applied Nuclear Physics, such as The Computer Automated Radioactive Particle Tracking Technique (CARPT) 1, Computed Tomography new hybrid beads ( CT, PET, SPECT ) or Compton Cameras are still unknown. This work presents the properties of PMMA-La2O3 spheres 2 . These spheres were synthetized by suspension polymerization using the recipe presented in Table 1. Then, they were characterized by Scanning Electron Microscopy (SEM) at the Nuclear Engineering Institute.
