摘　　要：目的评价某医院Precedence 16 SPECT/CT建设项目职业病危害放射防护的控制效果。方法依据国家相关放射卫生防护标准和方法,考虑建设项目涉及的2种辐射源:放射性药物(99mTc)产生的γ射线和CT中的X射线,对建成后项目工作场所的周围辐射水平进行检测评价和防护效果进行综合评估。结果不同岗位放射工作人员受照剂量不同,注射室护士手部(4 mSv/a),扫描室操作技师(0.1 mSv/a),给病人摆位技师(2.5 mSv/a)。结论该项目放射防护屏蔽效果良好,符合国家相关标准的要求。[Objective]To evaluate the control effect of radioprotection in construction project of SPECT/CT in a hospital. [Methods]According to relevant national standards and methods for radiation protection,the construction project was considered involving two kinds of radiation sources： radiopharmaceuticals（99roTc） generated γ-rays and the X-ray of CT,after the completion of the project,the protective effect of the workplace and the radiation levels around were comprehensively evaluated. [Results]Workers of different post received radiation at different doses： the hands of nurse in injection room（4 mSv/a）,operations technician in scanning room（0.1 mSv/a）,patient positioning technician（2.5 mSv/a）. [Conclusion]The project has a good shielding effect on radiological protection which accords with the relevant national standards.
