为进一步加强医用X射线的防护管理,降低受检者受照剂量,我们对山东省部分医院各类X射线检查受检者的现实剂量与正当剂量水平进行了调查。一、调查方法1.采用回顾性调查与前瞻性调查相结合的方法,计算出山东省部分各级医院各类X射线检查的频数及百分比。2.现实剂量水平调查:现实剂量水平即在对全省各级医院原有的X射线诊断设备与防护设施、透视条件、人员素质与操作程序没有任何限制与改进情况下,受检者一次检查所接受的皮肤照射量与全身有效剂量当量。首先将测得的皮肤照射量乘以各级医院
In order to further strengthen the protective management of medical X-rays and reduce the dose of the subject, we investigated the actual dosage and the proper dosage level of X-ray examination subjects in some hospitals in Shandong Province. First, the survey method 1. Using a combination of retrospective surveys and prospective surveys to calculate the frequency and percentage of various types of X-ray examination at some levels of hospitals in Shandong Province. 2. Actual Dose Level Survey: The actual dose level is in the province at all levels of the hospital’s original X-ray diagnostic equipment and protective equipment, perspective conditions, personnel quality and operating procedures without any restrictions and improvements, the subjects of a check The amount of skin irradiation received corresponds to the effective systemic dose. First, multiply the measured skin exposure by hospitals at all levels
