摘要:
目的 研究以使用18f-fdg为代表的正电子放射性药物过程中医务人员的受照剂量水平,为临床辐射防护提供参考数据。方法 应用热释光个人剂量对山东省两家医院pet/ct中心的工作人员进行监测。工作人员分别通过佩戴胸部剂量计、眼晶体和指环剂量计,监测其有效剂量当量和从事分装、注射人员的眼晶体剂量和手部剂量。结果 两家医院pet/ct 中心的17名工作人员的平均年有效剂量当量范围为0.09~2.03 msv,不同工作环节外照射个人累积剂量当量存在较大差别,受照剂量由高到低的操作依次为药物分装、注射、摆位、扫描或药物制备。受到较高剂量照射的操作人员的眼晶体剂量当量分别为0.38 msv/a(分装)和0.27 msv/a(注射),手部剂量分别为43.90 msv/a(分装)和17.75 msv/a(注射)。结论 在现有工作条件和工作负荷的情况下,pet/ct中心工作人员的平均年剂量当量水平符合国家标准中关于有效剂量、眼晶体和手部剂量限值的要求。
Abstract:
objective to measure the personal radiation dose for medical staff in pet/ct center and to offer the reference data for clinical radiation protection. methods apply tld methods to monitor the radiation workers’ dose of 2 pet/ct center in shandong province. chest dosimeter for body, lens dosimeter for eyes and ring dosimeter for fingers during distribution and injection. results higher dose of the procedures are distribution, injection, positioning, drug preparation and scanning in descending order. eye dose are 0.38 msv/a and 0.27 msv/a for distribution and injection; finger dose are 43.90 msv/a and 17.75 msv/a for distribution and injection. the average dose for one scanning can be calculated by workload. conclusion under the workload in the research, the doses received by staff members do not exceed the annual limit for professional persons. when the workload is dramatically higher per year, the dose may exceed the national radiation safety standards(gbss) on occupational annual dose limit.
