The details are not understood though it is thought that protists take on specialized roles on the transition of radioisotopes in soil. In this study, the three-dimensional distribution of Pb in a cell of 
in water including Pb was tried to measure with micro-PIXE and ML-EM (maximum likelihood expectation maximization) algorithm. As a result, it was found that the distribution of Pb was limited on the surface of the cell.

In the ML-EM for PIXE-CT, energy loss of incident particles and absorption of X-rays affect must be estimated using STIM-CT. This paper shows the appropriateness and the expected spatial resolution of this method are evaluated by a computer simulation and some practical experiments using 3 MeV proton microbeam with a diameter of 1m at TIARA. The PIXE-CT experiments were carried out using a dried unicellulate and human lung tissue as a test sample placed on an automatic rotation stage, which made a full turn by rotating 360
at each step of 18 in vacuum. In the simulation, X-ray yield and absorption were calculated using density distribution of two-dimensional Shepp phantom. The results of those simulation and experiments have proved that this method is effective in PIXE-CT.

In order to make elemental analysis in a minute cell, we developed in-air micro-PIXE analysis system in which light-ion microbeam of diameter 0.25m is used, and the imaging of the trace-element distribution was successfully carried out. This system is widely applied in the fields of medicine, biology, pharmacy, and dentistry.
