微量元素是人体的重要组成部分,而且,某些微量元素是人体所必需的。为了给中国参考人参数提供依据,为微量元素和健康关系的研究提供我国的当前资料,分析了10种器官和组织中（心、肝、脾、肺、肾、胃、甲状腺、小肠、肌肉和骨）30种元素的含量。 中子活化法是元素分析的最有效方法之一。利用超热中子活化法测定器官和组织中碘和溴的含量,利用仪器中子活化法测定铝、钙等其余28种元素的含量。分析条件分别为:1）中子注量率8×1011 cm-2·s-1,氮化硼作屏蔽材料,照射15min,冷却约5min,测量碘
Trace elements are an important part of the body, and some trace elements are essential to the body. In order to provide a reference for Chinese reference parameters and to provide current data for the study of the relationship between trace elements and health, we analyzed the distribution of trace elements in 10 organs and tissues (heart, liver, spleen, lung, kidney, stomach, thyroid, small intestine, muscle and Bone) content of 30 elements. Neutron activation is one of the most effective methods of elemental analysis. The content of iodine and bromine in organs and tissues was determined by super-heated neutron activation method. The content of the remaining 28 elements such as aluminum and calcium was determined by neutron activation. The analytical conditions are: 1) neutron fluence rate of 8 × 1011 cm-2 · s-1, boron nitride as shielding material, irradiation for 15min, cooling for about 5min, measuring iodine
