Micro particle-induced X-ray emission (micro-PIXE) was applied to determine the inter- and intracellular distribution of boron-10 (B) in tumor cells. The peak B atom measurement was large on the measurement spectrum in comparison to the circumference background. It was possible to confirm that B atoms were measured. But, the intracellular micro-distribution of boron could not be clearly detected in this analysis. Improvements are therefore necessary in the technical methods of cell fixation, while the micro-PIXE and PIGE analyzing system also needs to be further upgraded.
