对不同医院工作人员进行了2-脱氧-2-[F-18]氟-d-葡萄糖正电子发射断层扫描（18F-FDG PET）个体剂量当量的时间过程研究，并对日常工作职责进行了分析。对于测量，使用半导体剂量计。使用专用软件采集1 min和1 h间隔的值、月累积剂量和日累积剂量以及趋势图，并显示在读取器上。包括以下职责涉及最大外照射工作的放射工作人员：进行诊断的医生（4.8 μSv/程序）、移除注射针的护士（3.1 μSv/程序）、执行质量控制测试的药剂师（2.9 μSv/程序）、协助患者定位的核医学技术人员（6.5 μSv/程序）和进行日常检查的回旋加速器工程师（13.4 μSv/程序）。日常工作分析结果揭示了外照射剂量的影响因素。为了减少外照射剂量，研究者应缩短患者与18F-FDG源或患者示踪剂的接触时间。
Time-course study of individual dose equivalents of 2-deoxy-2-[F-18]fluoro-d-glucose positron emission tomography (18F-FDG PET) was conducted in different hospital workers, and the daily work duties were analyzed. For the measurements, a semiconductor dosimeter was used. The values at intervals of 1 min and 1 h, the monthly cumulative and daily cumulative doses, and trend graphs were acquired with dedicated software and displayed on the reader. The following radiation workers with duties involving maximum external exposure work were included: doctors making diagnoses (4.8 μSv/procedure), nurses removing injection needles (3.1 μSv/procedure), pharmacists performing quality control tests (2.9 μSv/procedure), nuclear medicine technologists assisting patient positioning (6.5 μSv/procedure), and cyclotron engineers performing daily checks (13.4 μSv/procedure). The results of analysis of daily work duties revealed the influencing factors of external exposure dose. To reduce the external exposure dose, investigators should shorten the patient’s contact time with the18F-FDG source or patient tracer.
