Radiation effects of nuclear physics rays on hepatoma cells.

The traditional method of cloning formation is used to study the radiation effect of nuclear physics rays on hepatoma cells, and the results obtained are not reliable. Therefore, a new method of studying the radiation effect of nuclear physics rays on hepatoma cells is proposed. PCC method is used to study the radiation effect ofγ-rays on hepatoma cells. Radiation effects of X-rays on hepatoma cells were studied by radionuclide formation assay, neutral comet electrophoresis and γH2AX focal detection. The results showed that the survival curves of HepG2 hepatoma cells irradiated byγ-rays were well fitted by linear squares. There was a linear relationship between the survival rate and irradiation dose of HepG2 hepatoma cells irradiated byγ-rays. HepG2 hepatoma cells showed strong tolerance to X-ray irradiation, and the positive rate of H2AX cells reached 100% in each dose group only 0.5 h after X-ray irradiation. [ABSTRACT FROM AUTHOR]
