Abstract

A radiochemical group separation using APDC extraction was applied to the neutron activation analysis of normal and cadmium injected rat liver. In order to optimize determinations of induced radionuclides with various half lives, the gamma-ray spectra were obtained after various decay times. Eight elements, Cd, Co, Cu, Fe, Mn, Mo, Se and Zn, were determined from rat liver samples within 12 day after irradiation. Although Cd, Cu and Mo in normal rat liver could not be detected by nondestructive method, they could be determined after the extraction. The tendency was seen that the concentration of all the elements as mentioned above are increased by cadmium injection. In particular, zinc and copper exhibited high values.

摘要

采用APDC萃取进行放射化学分组分离，应用于正常大鼠肝脏和注射镉的大鼠肝脏的中子活化分析。为了优化对具有不同半衰期的诱发放射性核素的测定，在不同衰变时间后获取γ射线光谱。在照射后12天内从大鼠肝脏样品中测定了8种元素，即镉、钴、铜、铁、锰、钼、硒和锌。虽然正常大鼠肝脏中的镉、铜和钼用非破坏性方法无法检测到，但萃取后可以测定。可以看出，上述所有元素的浓度都因注射镉而增加。特别是，锌和铜的值较高。
