Body surface exposure to X-ray radiation was measured in those with synthetic clue investigation on tuberculosis. The results showed body surface exposure in them appeared a logarithmic normal distribution with a geometric mean of 0.19 mC/kg and was higher than that with fluoroscopy in routine check-ups. The late effect of X-ray radiation showed 0.52 hours of an average life-span cut. But, based on prevalence, mortality and cure rate of chemotherapy for tuberculosis in Jiangsu Province, chest fluoroscopy in synthetic clue investigations brought an average prolongation of 45.8 hours per person in life-span of those X-rayed. Comparison of life-span showed synthetic clue investigation was an adequate method in active tuberculosis case-finding from the viewpoint of radiation protection.
对进行结核病综合线索调查的人群测量了体表X射线辐射量。结果显示，他们的体表辐射量呈对数正态分布，几何平均值为0.19 mC/kg，高于常规体检中透视检查的辐射量。X射线辐射的后期影响显示平均寿命缩短0.52小时。但是，根据江苏省结核病化疗的患病率、死亡率和治愈率，综合线索调查中的胸部透视使接受X射线检查者的人均寿命平均延长了45.8小时。寿命比较表明，从辐射防护的角度来看，综合线索调查是活动性肺结核病例发现的一种适当方法。
