实 验以体外 培养的 小鼠 B16 黑色 素瘤细 胞为 材料, 在50 Me V/u 12 C6 + 离子 的展 宽 Bragg峰区辐 照细胞 ,得到的结 果是这 种离子的 O E R 值为 125 。说明这 种能量的 离子具 有低的氧 效应。
In the experiment, the B16 melanoma cells cultured in vitro were used to irradiate cells in the broadened Bragg peak region of 50 Me V / u 12 C6 + ions. The result showed that the O E R value of this ion was 1.25. The ions that illustrate this energy have a low oxygen effect.
