放射性元素

Now I'm injecting a material that's tagged with a radioisotope.

我现在在注射一种以放射性同位元素做为标记的物质

Ernest Rutherford and Frederick Soddy were working out the nature of radioactivity.

是卢琴福和索迪揭示了放射性的奥秘，发表了元素的嬗变理论。

Academic achievement:(1) early study of the electromagnetic wave transmitting and receiving;(2) found that there is penetration of uranium weak penetration of the α and β two kinds of radiation;(3) and Soddy worked together to propose release of radioactive atoms can be α or β atom into another element.

学术成就：（1）早年研究电磁波的发射和接收；（2）发现铀中有穿透力弱的α和穿透力强的β两种辐射；（3）和索迪合作提出放射性原子可以通过放出α或β变成另一种元素的原子。

In 1898, the Curies obtained a new element, whose radioactivity was several million times stronger than that of uranium.

1898年，居里夫妇获得了一种新元素，它的放射性比铀强几百万倍。

Radioactivity is the energy given off by rays from a few unstable elements such as uranium and thorium.

放射性是某些不稳定元素如铀和钍的射线放射出来的能量。

In the process of mining, milling and steel and rare earth melting, thoron element was released to the accessible environment together with smoke, wastewater and disposed slag, leading to radioactive contamination to the environment.

在采矿、选矿、钢铁和稀土冶炼等生产中，钍元素随烟尘、废水和废渣排放至环境中，造成放射性污染。

A radioactive transuranic element which has been ''.

一种合成的放射性超铀元素。

A radioactive transuranic element which has been synthesized.

一种合成的放射性超铀元素。

The concept behind the ABR is to "burn" the transuranic elements, such as plutonium and other long-living radioactive material.

背后的概念ABR是"烧"的超铀元素，如钚和其他长期居住放射性物质。

A radioactive transuranic element; discovered by bombarding ''.

一种放射性超铀元素，在用α粒子轰击''。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
