摘要
PET/CT中心使用^(18)F-FDG作为正电子放射性诊断药物,为此研究该中心的辐射水平,为临床辐射防护提供参考依据。利用X、γ辐射剂量率仪测量各工作区的辐射剂量率,利用热释光剂量仪估算工作人员的年有效剂量,并进一步研究了作为放射源的受检者离开前,周围人员与其保持不同距离时的辐射剂量率。结果表明:PET/CT中心各工作区及工作人员的辐射剂量符合国家标准。当周围人员与受检者保持3 m以上距离时,所测辐射剂量率近似环境本底值。
The PET/CT center used 18F-FDG as a positron diagnostic drug to investigate the radiation level of the center. It provided a reference for clinical radiation protection. Radiation dose rate of each working area was measured by radiation dose rate meter. Personal annual effective dose was monitored by thermoluminescent dosimeter,and the radiation dose rate at different distances from examinees was studied. It was found that the radiation dose rate of working area and staff in PET/CT center met the national standard. The radiation dose rate was close to the environmental background beyond 3 m away from the examinee.
