肿瘤是严重危害人类健康的疾病之一,靠单一治疗手段往往难以达到根治效果。放射性核素内照射治疗作为外科手术、化疗、放疗等手段的补充,在肿瘤治疗中的应用正逐渐受到重视。放射性核素肿瘤治疗是一种系统特异性的靶向治疗,其主要是利用载体或采取介入措施,将用于治疗的放射性药物定向运送到病变组织和细胞。由于核医学科应用的口服、注射的放射性药物活度大,医务人员在给病人诊断、治疗时接触放射药物时间较长,剂量又较大,医务人员、患者均可能因受到较大剂量的照射而受到伤害,因此,做好核医学科的辐射安全防护工作是所有开展放射
Tumor is one of the diseases that seriously endanger the health of human beings. It is often difficult to achieve the radical effect by a single treatment. Radionuclide irradiation as a surgical, chemotherapy, radiotherapy and other means of supplement, the application in the treatment of cancer is gradually receiving attention. Radionuclide oncology therapy is a system-specific targeted therapies that target the delivery of radiopharmaceuticals for therapeutic delivery to diseased tissues and cells primarily through the use of carriers or interventions. As the nuclear medicine applied oral, injection of radiopharmaceutical activity, medical staff to the patient diagnosis and treatment of exposure to radiopharmaceutical longer, the dose is larger, medical staff, patients may be subject to a larger dose of radiation And be harmed, therefore, to do a good job in nuclear medicine radiation protection work is all radiation
