摘要
用仪器中子活化法在微型反应堆上对小鼠的毛、脑、心肝、肾、肺、肌肉、肿瘤等８种组织中Ｂｒ、Ｃａ、Ｃｌ、Ｃｕ、Ｉ、Ｋ、Ｍｇ、Ｍｎ、Ｎａ、Ｓ和Ｖ等１１种元素进行了测定。其中铜的分析利用６５Ｃｕ（ｎ，γ）６６Ｃｕ反应，通过测定６６Ｃｕ的１０３９．６ｋｅＶγ射线强度进行定量。方法可靠性用ＮＢＳ－１５７７（牛肝）、ＩＡＥＡ－Ｈ４（肌肉）、虾粉等标准物质核对，测定值与推荐值相一致。
In order to study the correlation of trace elements with liver cancer,the content of 11 elements of Cu,Ca,Mn,etc.in mice's hair,brain,heart,lung,kidney,muscle and tumor tissues were determined by neutron activation analysis using a miniature neutron source reactor. The content of copper was analyzed by determining 1039.6keV γ-rays of 66Cu.The standard reference materials NBS-1577,IAEA-H4 and shrimp powder were also determined,of which the results were in agreement with the recommended values.
