为探讨医用诊断X线工作人员辐射防护工 作的重要性,我们对我院1996～1999年从事医用诊断X线的工作人员进行工作量和X线吸收剂量水平的监测研究,现报告如下。 资料和方法 1 研究对象 我院从事医用诊断X线的各类工作人员共158例,其中男性100例,女性58例,放射工龄1～45年,平均11.5年。 2 测量方法 采用热释光剂量(TLD)方法测量X线吸收剂量。以玻璃管封装的LiF(mg cup)粉末作为监测剂量元件,其探测下限小于0.2mR,在1×10~(-3)～1000R之间具有良好线性。经 In order to explore the importance of radiological protection of X-ray staff in medical diagnosis, we conducted a study on the workload and X-ray absorption dose monitoring of medical X-ray staff in our hospital from 1996 to 1999, and are reported as follows. Materials and Methods 1 Subjects There were 158 staff members working in X-ray of medical diagnosis in our hospital, including 100 males and 58 females, with a working age of 1 to 45 years and an average of 11.5 years. 2 Measurement method The thermoluminescence dose (TLD) method to measure the X-ray absorption dose. The glass tube encapsulated LiF (mg cup) powder as a monitoring dose element has a lower detection limit of less than 0.2 mR and a good linearity between 1 × 10 -3 and 1000 R. through
