目的为掌握辖区内五种类型的x射线机对受检者的剂量照射情况,以保证医用辐射安全。方法按照国家的相关标准规定,于2008年4~10月份,对448例受检者的受照射剂量进行了监测。结果选取一家三级、两家一级医疗单位的五大类X射线的机种的9台机器,其中数字胃肠机2台,DR机3台,CR机2台,普通胃肠机1台和屏片机1台。测量这9台机器进行诊断检查时受检者各部位的剂量。结论五种机型中应特别注意普通胃肠机作上消化道检查时的防护和操作规范,以降低受检者的受照射剂量。
Objective To understand the dose exposure of five types of X-ray machines in the area to ensure the safety of medical radiation. Methods According to the relevant national standards, the radiation dose of 448 subjects was monitored from April to October in 2008. Results Nine machines of five major types of X-ray were chosen from three levels and two first-level medical units, including 2 digital gastrointestinal machines, 3 DR machines, 2 CR machines, 1 ordinary gastrointestinal machine, Screen machine 1 Taiwan. Measure the dose of various parts of the subject during the diagnostic tests of the nine machines. Conclusion Five kinds of models should pay particular attention to the general gastrointestinal machine when the upper gastrointestinal tract protection and operation practices to reduce the subject’s exposure dose.
