【摘要】 作者考虑到医学辐射防护对人类健康的特别重要性,为了能及时监测机体受放射性核素内污染的情况,研究设计了用各种不同水平的放射自显影术进行不同条件内污染的监测。先后摸索成功了用冰冻微观放射自显影术来监测体内呈游离态和结合态的内污染核素;涂片放射自显影对污染机体的血、髓、尿和粪样进行监测;并设计探讨用双标记放射自显影术对复合污染的核素进行鉴别监测;尤其是我们摸索成功的将闪烁液直接渗入液体乳胶中的荧光增敏放射自显影术,可以提高灵敏度达10倍之多,从而显著提高对低水平内污染核素的监测能力。更多还原

【Abstract】 In view of the exceptionally important role of the medical radiation protection in human health? in this paper we try to study on the monitoring of internal contamination of radionuclides in organism by different autoradiogra-phic methods* such as: monitoring of the body retention of isolated or combined radionuclides by freezing microautoradiography; monitoring of blood>bone marrow and excreta radioactive samples by smear autoradiographyi differentiation of two radionuclides contamination by double radionuclide autoradiogra-phy? especially? monitoring of low level of radionuclides contamination by fluorescence sensitization autoradiography. The sensitivity of autoradiographic formation was increased by the scintillator by 10 times.更多还原
