1987年我们对X线、同位素工作者进行了健康检查,发现吸~(131)腆(~(131)I)率异常为数不少。大剂量X线可对人体各器官、组织造成损伤,早已被大量的临床、实验等证实。而小剂量的X线对人体是否有损害,仍在探讨中,国内外已有不少报道。本文就146例医用X线工作者甲状腺吸~(131)I率降低、偏低与50例健康者进行对照分析。 In 1987, we conducted a health examination of X-ray and isotope workers and found that there were a large number of abnormalities in the rate of ~ (131) 腆 (~ (131) I). High-dose X-ray can cause damage to various organs and tissues of the human body and has long been confirmed by a large number of clinical trials and experiments. The low-dose X-ray on the human body whether there is damage, still under discussion, there have been many reports at home and abroad. In this paper, 146 cases of medical X-ray workers thyroid suction ~ (131) I rate decreased, low and 50 healthy controls were analyzed.
