These phenomena could be explained by the different local energy deposition as illustrated by the track structure composed of core with high-density ionizations and penumbra with scattered delta-rays. We discussed the relationship between the track structure and cell death in mammalian cells or 8-hydroxy-2'-deoxyguanosine (8-OHdG) formation by different ion species with the same LET. In addition, we tried to provide experimental basis for the oxygen-in-the-track hypothesis that explains the decreased oxygen effect in the high LET region by measuring 8-OHdG under hypoxic condition.}, pages = {9--12}, title = {細胞やDNAへの影響から見たトラック構造}, year = {2010} }
