业已证实,急性或高剂量率照射可破坏或抑制大多数免疫反应。T 和 B 细胞都是辐射敏感的,但对急性照射一般 B 细胞比 T 细胞敏感,而被促有丝分裂素或抗原活化的 T 细胞则极不敏感.虽然,慢性照射能降低抗体形成、空斑形成细胞数和某些细胞免疫反应,但关于低剂量率照射对 T 和 B It has been demonstrated that acute or high dose rate irradiation can destroy or inhibit most immune responses. Both T and B cells are radiation-sensitive, but B cells are more sensitive to acute radiation than T cells and less sensitive to mitogen-activated or antigen-activated T cells.Although chronic irradiation reduces antibody formation and plaque formation The number of cells and some cellular immune responses, but about low dose rate irradiation on T and B
