摘　　要：血液辐照在我国被广泛应用。血液辐照的主要目的是防止免疫缺陷性病人染上输血相关性移植物抗宿主病。其机理为:通过对需要输注的血液制品进行低剂量辐照,灭活血液中的活性淋巴细胞,防止其增殖。大量研究和实践表明,没有发生明显副作用,该项技术已在医院血站和用血相关机构中广泛应用。针对血液辐照项目,在工程分析的基础上,对血液辐照可能带来的辐射环境影响进行了详细分析,预测和评价了项目建设对辐射环境可能造成的影响,并针对性地提出了环境保护措施。Blood irradiation is widely practiced in China. The main purpose of this process is to prevent graft versus host disease into immunodeficiency patients. This is achieved by the abrogation of T-lymphocytes, as a result of specific effect of ionizing radiation at low doses applied. As demonstrated by a lot of studies, there are no accompanying significantly deleterious effects, and therefore the technique has acquired wide utilization in hospital and transfusion services, blood banks, and related institution. This paper discussed radiological environmental impact assessment of blood irradiation and blood components. Based on the project description, a systemic radiological environmental impacts has been identified. The environmental impacts were predicted and assessed.The environmental protection measures are also proposed.
