36. 电离辐射对免疫系统的影响可通过估计细胞数量的变化或使用功能性分析来进行评估。此类免疫反应变化的影响取决于辐射剂量、与免疫接种的时间联系和遗传特征等因素，因此：
36. The effects of ionizing radiation on the immune system can be assessed by estimating changes in cell numbers or by using a variety of functional assays. The impact of such alterations in immune response depends on factors such as dose of radiation, its temporal relation to immunization and genetic disposition. Thus:
