除天然辐射照射外,医疗照射是澳大利亚公众总的辐射负担中唯一最大的来源。为确定核医学中应用放射性药物造成的澳大利亚公众剂量,进行了一项调查。在调查中,用澳大利亚核医学中心提供的资料估算了由于施用放射性药物而造成的平均有效剂量。调查了69个中心,要求每个中心提供1991年6月24日到7月21日的4周内每个病人的下述详细资料:放射性药物、施用活度、年龄、性别、体重(对<15岁的儿童)及怀孕时期(如果怀孕)。用ICRP 60号出版物和53号出版物提供的方法和参数进行了有效剂量估算并对特定年龄组进行修正,从而给出了每种放
In addition to natural radiation exposure, medical exposure is the single largest source of total radiation burden on the Australian public. A survey was conducted to determine the public dose in Australia for the use of radiopharmaceuticals in nuclear medicine. In the survey, the information provided by the Australian Nuclear Medicine Center estimated the average effective dose due to the administration of radiopharmaceuticals. A total of 69 centers were investigated and each center was requested to provide the following details for each patient within 4 weeks from June 24 to July 21, 1991: radiopharmaceutical, activity, age, gender, weight (for < 15 years old) and during pregnancy (if pregnant). Effective dose estimates were made using methods and parameters provided in ICRP Publication No. 60 and Publication No. 53 and amendments were made to specific age groups to give an indication of each dose
