对甲状腺功能亢进(以下简称甲亢)患者,~(131)Ⅰ不但有令人满意的疗效,而且有治疗费用低、并发症少、方便无痛、安全可靠等特点。近年来成都市这项治疗技术发展较快。在20世纪80年代末,全市仅有2家省级医院开展这项业务,至1998年,全市已发展到9家医院,年治疗达15 000余人次。由于接受~(131)Ⅰ治疗的甲亢患者口服放射性药物剂量较大,因而操作医生所受到的剂量也可能较大。同时,患者接受治疗后未在医院隔离而直接回家,也可能给家庭环境造成一定的放射性污染,对家庭成员或其他密切接触者形成不必要的照射。因此,开展~(131)Ⅰ治疗甲亢的频率与相关剂量调查,提出相应的防护措施,对于合理实施医疗照射,保护医生、患者和公众的健康与安全均有重要意义。
For patients with hyperthyroidism (hereinafter referred to as hyperthyroidism), ~ (131) Ⅰ not only has satisfactory curative effect, but also has the advantages of low cost of treatment, less complications, convenient and painless, safe and reliable. In recent years, Chengdu, the treatment technology developed rapidly. In the late 1980s, only two provincial hospitals in the city carried out this business. By 1998, the city had grown to 9 hospitals and treated over 15,000 people annually. Due to the large doses of oral radiopharmaceuticals received by 131I-treated hyperthyroid patients, the operating physician may experience a greater dose. At the same time, patients who return home without isolation in the hospital after receiving treatment may also cause some radioactive contamination of the home environment and form unnecessary exposure to family members or other close contacts. Therefore, to carry out ~ (131) Ⅰ treatment of hyperthyroidism frequency and related dose survey, put forward appropriate protective measures for the rational implementation of medical exposure, protection of doctors, patients and the public health and safety are of great significance.
