摘要
重离子是原子序数≥2的原子被剥掉或部分剥掉外周电子后带正电荷的原子核,它主要来自于太阳系外的带电粒子。虽然重离子占宇宙射线的比例只有1%,但由于它能够形成Bragg峰,产生巨大的能量沉积,因此对较为敏感的免疫器官所造成的生物学效应要比电磁辐射等射线严重得多。本文主要简述了重离子对免疫器官、免疫细胞及染色体等几个方面的生物学效应,为研究重离子辐射对免疫系统的影响提供参考。
Heavy ions are the positively charged nuclei of the atomic number greater than two in the universe, which mainly comes from the charged particles of the solar system outside. Heavy ions occupy only 1% in cosmic ray, but because they are is capable of forming the Bragg peak, resulting in huge energy deposition, they have much more severe biological effects on immune organ than electromagnetic radiation in the cosmic rays. This paper outlines the biological effects of heavy ions on several aspects of immune organs, immune cells and chromosomes, and provide a theoretical basis for the study of the impact of heavy ion radiation on the immune system.
