Dicentric Chromosomal Aberration As Nano Dosimeter Model

Chromosomal aberrations is one important biological damage for exposure to both directly and indirectly ionizing radiation. By modeling the dicentric aberration damage we get the response curve in terms of biological parameter effective cross-section which represent the probability of interaction in unit area μm2 versus the best physical parameter mean free path.The proposed radiobiological model may use as new technology in radiotherapy (as biodosimeter).
