Resumo |
Human hepatoma and normal liver cells were irradiated with C-12(6+), ion beams (LET= 96.05 keV/mu m) and gamma-rays at Heavy Ion Research Facility in Lanzhou (HIRFL). The chromatid breaks and break types were detected using the premature chromosome condensation technique. Our experimental results showed that chromatid breaks seem to have a good relation with C-12(6+) absorbed dose and C-12(6+) are more effective to induce chromatid breaks as compared to they-rays. For C-12(6+) ion irradiation the major break was isochromatid break, while chromatid breaks were dominant for gamma-ray irradiation. We also observed that the Relative Biology Effectiveness (RBE) of C-12(6+) ion is about 2.5 times higher than that of gamma-rays. |
