目前,我省使用X线单位1477个,共有医用诊断X线机2003台。使用工业X线机单位119个,共有探伤机281台。为了加强射线装置管理和X线测量的质量控制,使全省测量结果具有可比性,我们对吉林省现有的X线巡测仪进行了一次相对测量比对。一、相对测量比对仪器我省目前应用的各系列X线巡测仪其中有Xs一系列32台、WF一系列5台、FJ一系列8台、Z一系列1台,现有44个单位46台仪器参加本次全省性测量比对。二、相对测量比对方法 At present, our province uses 1477 x-ray units, a total of 2003 medical diagnostic X-ray machine. The use of industrial X-ray unit 119, a total of 281 flaw detector. In order to strengthen the quality control of ray device management and X-ray measurement and make the measurement results of the province comparable, we conducted a relative measurement comparison to the existing X-ray detector in Jilin Province. First, the relative measurement of the instrument compared to the current series of X-ray detector used in our province which has a series of Xs 32, WF a series of 5, FJ a series of 8, Z a series of 1 units, the existing 44 units 46 instruments to participate in the comparison of the province’s measurement. Second, the relative measurement method
