MICRO-BEAM SCANNING PIXE IN NIRS AND THE APPLICATION TESTS TO BIOLOGICAL SAMPLES
Preview AbstractMicro-beam scanning system for PIXE analysis newly installed in National Institute of Radiological Sciences (NIRS) was introduced in this paper. Fine ring structure of a fish scale was observed using elemental mapping with proton micro-beam scanning. Pollen was analyzed as one example of single cell to demonstrate the elemental distribution. The minimum size of the proton beam is estimated as 0.4×0.65 μ m.
