放射性核

The heavy elements in the theory of spontaneous metamorphosis immediate sensation around the world ;(4) is proposed to estimate the Earth's radiation age;(5) from the charge-mass ratio α which is derived helium ions;(6) from the scattering of α Bighorn recognized atomic mass concentrated in a radius of 10-12 meters in the nuclear, on positively charged core surrounded by negatively charged electrons;(7) with natural α-particles from the nitrogen nuclei in the outgoing protons, this is the first time human beings to change the chemical elements of artificial nuclear reactions;(8) predicted that heavy hydrogen and neutron sub-existence .

这一重元素自发蜕变理论立即轰动全世界；（4）提出用放射性估算地球年龄；（5）从α的荷质比得出它是氦离子；（6）从α大角散射认识到原子质量集中在半径为10－12米的核上，核带正电，周围是带负电的电子；（7）用天然α粒子从氮原子核中打出质子，这是人类第一次实现改变化学元素的人工核反应；（8）预言重氢子和中子存在。

Radioactive decay studies have found a kinds of elements can be α or β decay and the decay into another element, while the α-decay product of -α-rays became one of the deep structure of the material means of .1911, the Rutherford and others bombarded atoms with α-rays observed wide-angle deflection to determine the nuclear structure of atoms and nuclei was first proposed the term .1919 year, Rutherford and others have also found that with α-ray bombardment of nitrogen will release the nuclear protons, this is the first time Artificial realization of a nuclear reaction, after the bombardment of nuclei with the radiation caused by nuclear reaction method to become the primary means of research in nuclear.

放射性衰变研究发现了一种元素可以通过α衰变或β衰变而变成另外一种元素，而α衰变的产物——α射线又成了人们探讨物质深层结构的手段。1911年，卢瑟福等人用α射线轰击原子、观察到大角度偏折，从而确定了原子的有核结构，并首次提出原子核这一名词。1919年，卢瑟福等人又发现用α射线轰击氮核会放出质子，这是首次用人工实现的核反应，以后用射线轰击原子核来引起核反应的方法逐渐成为研究原子核的主要手段。

TGS method can determine quantitatively with high accuracy transuranic nuclides in heterogeneously distributed media with medium- and high-density, and is thus widely used to assay the location and quantity of selected radioisotopes in scraps and wastes within sealed containers.

它是专用于准确定量测量中、高密度非均匀分布介质中的放射性核素及其含量，是核设施中可回收物以及核废物测量分析的主要方法之一。

SMI had protection and therapeutic effects on leucocytopenia of mice induced by irradiation.

试验还显示，照射后四天SMI大、中剂量组小鼠骨髓有核细胞数与正常对照组无显著性差异，说明其骨髓造血功能比较活跃，提示SMI对放射性损伤所致小鼠血虚证有一定的保护和治疗作用，对于小鼠白细胞减少有较好的治疗效果。结论：SMI对小鼠放射性损伤所致血虚证有一定的保护和治疗作用。

The electrolytic decontaminating method may be used for eliminating radioactive contaminant from metal parts of exservice nuclear installation, so that the metal waste may be degraded and reused.

本方法可广泛用于核设施金属表面放射性污染的电解去污，使核设施退役时产生的大量金属废物得以降级或再循环、再利用。

In order to achieve the required angular resolution, a sophisticated tracking detection system was established to reconstruct the track of each incident particle, as well as each scatted particle. The upstream detection system consisted of two plastic scintillators (T1 and T2) and two low-pressure multiwire proportional chambers .

He是结构性质比较典型的丰中子核，也是RIBLL可以产生的束流强度较大的放射性核素。2001年3月，我们利用兰州近代物理研究所的放射性次级束流线装置提供的25MeV/n的〓He轰击〓Be和〓Li靶，进行了〓He+〓Be的准弹性散射的研究。

The neutrinos are used for fundamental physics experiments, but the proton beam that is produced at the start (this hits the target rod at the beginning of the simulation you download) is also going to be used in experiments for neutralising radioactive waste by transmuting the radioactive elements into stable ones.

中微子使用为根本物理实验，但导致在开始的氢核射线(这击中目标标尺在模仿开始您下载)并且被使用在实验为中立化放射性废物由transmuting 放射性元素入槽枥一个。

With the progress of nuclear medicine and space physiology, People become more and more interesting in the radiation injury and it s protection study.
