医疗照射来源于X线诊断、核医学诊断和放射治疗。目前,医疗照射频度逐年增加。为摸清我省医疗照射水平和提供放射防护标准依据,我们于1984年7月开始对全省进行了医疗照射频度调查。全省总人口28552942人,一般农业县791,省会医院36个。共有诊断X线机1410台,核医学诊断22家,放射治疗5家。调查方法一、本次调查采取的方法是前瞻性调查,调查时间为一年。调查项目主要是:透视、消化道检查、各种照片、特殊造影、核医学诊
Medical irradiation comes from X-ray diagnosis, nuclear medicine diagnosis, and radiation therapy. At present, the frequency of medical radiation has increased year by year. In order to understand the level of medical radiation in our province and provide basis for radiation protection standards, we began to investigate the frequency of medical irradiation in the province in July 1984. The province has a total population of 28,552,942, a general agricultural county of 791, and 36 provincial capital hospitals. A total of 1,410 X-ray machines were diagnosed, 22 nuclear medicines were diagnosed, and 5 were radiation therapy. Survey Method 1. The method used in this survey was forward-looking investigation. The investigation time was one year. Survey items are mainly: perspective, digestive examination, various photos, special imaging, nuclear medicine
