为了调查北京放射工作者个人剂量的水平并估算集体剂量,我们在1986年采用双TL元件,对北京市319个放射性工作单位(7类放射性工作)中的1761名放射工作人员的个人剂量作了监测。 1 材料与方法 1.1 监测对象共累计监测了2284名放射工作人员。经核查剔除了不真实的剂量,并剔除1年内监测次数低于3次者,剩余的有效监
In order to investigate the individual dose levels of radiologists in Beijing and to estimate the collective dose, we used a double TL element in 1986 to quantify the individual doses of 1761 radiation workers from 319 radiological units in Beijing (7 types of radiological work) monitor. 1 Materials and Methods 1.1 Monitoring objects A total of 2,284 radiation workers were monitored. After verification, untrue dosimetry was eliminated and the number of monitoring times less than 3 times within 1 year was excluded. The remaining effective monitoring
