It delivers a focused vertical microbeam of 3.4 MeV protons to either or both of a targeted cell nucleus and cytoplasm. Such advantages of the SPICE have motivated further investigations on the cellular response to different DNA damage complexities induced by ionizing radiation. Previously, we reported an accurate and systematic investigation of the SPICE microbeam profile using a fluorescent nuclear track detector (FNTD). In the present study, as a second step, we discuss the localized dose distribution in targeted nuclei of human lung normal WI-38 cells and its correlation with intensity and area of DNA double strand breaks (DSBs) region, visualized by immunostaining against g-H2AX. Finally, superlinear dependence of the g-H2AX spot area to the beam area was interestingly observed for a large\nnumber of protons per position, suggesting that the penumbra dose fraction in the localized dose distribution significantly contributed to the DSB induction.
