低能质子辐照活体细胞的能量沉积特性

Energy Deposition Properties of Living Cells by Low Energy Protons Irradiation

  • 摘要: 为了研究带电粒子与活体细胞的相互作用,利用能量为2,2.5,3 MeV的质子外束,在室温环境下对厚约50 nm的氮化硅支持膜上的毕赤酵母菌进行辐照,并用金硅面垒探测器测量其透射能谱,通过对能量沉积特性的分析,表明质子外束穿过毕赤酵母菌后能损随入射能的增大而减小,但能量歧离随入射能的增大而增大。

    To study the interaction of charged particles with biological living cells,we delivered 2,2.5 and 3 MeV protons outside vacuum as external beam at room temperature to irradiate yeast Pichia cells which are supported by 50 nm thick silicon nitride film and the transmission energy spectrum were measured by an Au-Si surface barrier detector to analyze energy deposition properties.The results demonstrate that the energy loss decreases with the incident protons energy increase,but the energy straggling increases with incident protons energy increase.
