So far found that there are more than 2800 kinds of nuclides, in addition to 271 kinds of stable isotope and the rest are about 2530 kinds of radiation nuclide, including natural and artificial radionuclides radionuclides.

到目前为止发现的核素有2800多种，除271种是稳定的核素，其余约有2530种是放射线核素，包括天然放射性核素和人工放射性核素。

Because of the administration and equipment, the radiation accident in which radioactive nuclide and rays do harm to the public or the workers directly or indirectly occurs sometimes.

由于管理或设备的原因，核技术应用中放射性核素、射线直接或间接对工作人员或公众的健康、安全造成危害的放射性事故时有发生。

Radioisotope means the nuclide in a certain element with radioactive decay, which has the same ordinal number of atoms but different mass.

放射性同位素，是指某种发生放射性衰变的元素中具有相同原子序数但质量不同的核素。

According to distance protection,time protection and material protection to protect;contamination with radionuclides should be treated in accordance with its mutual imˉpaction.

放射性核素的防护应采取距离、时间、材料防护；放射性核素污染应根据污染特点进行去污处理。

Methods: A early model of brain radiation-induced injuries in the rat was developed. Analysis of the expression of TNF-α TNFR1 and TNFR2 in the pallium was done at different dose and time level after whole-brain irradiation with immunohistochemistry and computer technology.

在大鼠早期脑放射性损伤模型基础上，应用免疫组织化学方法染色标本，运用计算机图像技术计算并分析大鼠大脑放射性损伤后大脑皮质区在不同剂量、不同时间点TNF-α、TNFR1和TNFR2的动态表达。

We summarize the study of geochemistry of the Co rich crust, and explain the diffusion of elements in the Co rich crust and the exchange with ambient seawater. Besides, we discuss the effect of phosphatization and substrate rocks on the composition of the Co rich crust. We also introduce the application of stable isotopes (including the stable isotopes of Pb, Nd, and Hf), radioactive...
