1.The sediment was dated based on the ratio of two nuclides.

2.He explained that if the rock can " see the sky" it collects these nuclides.

3.They measured beryllium-10 and carbon-14 nuclide levels and found that concentrations were nearly zero.

4.These particles react with minerals in rocks to produce radioactive nuclides, a class of atoms.

5.It adds that the existing treated wastewater still contains other radionuclides and needs to be further purified.

报告还称，现有经过处理的污水中仍含有其他性，需进一步净化处理。

6.This is possible because the two nuclides break down at different rates, through the process of radioactive decay.

这是可的，因为这两种在性衰变过程中以不同的速率分解。

7.Miescher found a substance he didn't recognize and called it nuclein (because it resided in the nuclei of cells).

米歇尔发现了一种他不认识的物质，他给它取名为（因为它寄居在细胞里）。

8.It's uncertain whether the ALPS can remove tritium, carbon-14 and other radionuclides effectively based on past experience, Deng said.

邓说，根据过去的经验，ALPS 否有效去氚、碳-14 和其他性还不确定。

9.A water treatment system removes radionuclides and reduces radioactivity.

水处理系统去性并降低性。机翻

10.But that date has been overthrown by work employing cosmogenic nuclide dating.

但该日期已被采用宇宙成因测年的工作推翻。机翻

11.He added that the decay rate of these nuclides shows that the rock had not been exposed during the Holocene Era.

他补充说，这的衰变率表明，岩石在全新世时代并没有暴露出来。

12.Her MUGA had an ejection fraction of 19% with no focal wall motion abnormalities.

性活动血管扫描结果提示血分数为19％无局部心室壁运动异常。

13.A radionuclide cystogram uses a similar procedure as the VCUG, except that it uses a radioactive tracer injected into a blood vessel.

性膀胱显像和VCUG的过程相似，只不过需要静注性示踪剂。

14.Every time a nuclear weapon goes off - which happens more often than you think - it spreads radionuclides.

每次武器爆炸——这种情况比你想象的更频繁——它会传播性。机翻

15.It is possible that the composition of the radionuclides are proving more dangerous to the Fukushima birds than they are to the birds near Chernobyl.

也许是因为福岛的性成分对鸟类更危险。

16.The offshore discharge of ALPS-treated water is an issue that cannot be postponed in order to advance the decommissioning of the plant and the reconstruction of Fukushima.

为了推进电站的退役和福岛的重建，向近海排经过多去设备处理的水不推迟。

17.A sophisticated dating technique, called cosmogenic nuclide dating, has upended previous estimates—and, with that, is rewriting an important chapter in the story of human evolution.

一种称为宇宙成因测年的复杂测年技术推翻了之前的估计，并由此改写了人类进化史的重要篇章。机翻

18.To test that idea, they directly dated the cave breccias in Members 2 and 4 using cosmogenic nuclide dating, which Dr Granger helped develop.

为了验证这个想法，他们使用格兰杰博士帮助开发的宇宙成因测年法，直接对成员 2 和成员 4 中的洞穴角砾岩进行了测年。机翻

19.Melted nuclear fuel debris inside the damaged reactors is being cooled by pumped-in water, which comes into contact with a toxic cocktail of radioactive substances known as radionuclides.

受损反应堆内的熔化燃料残渣通过注入的水进行冷却，这水与一系列有毒的性物质（即性）接触。

20.Tepco said for years that its purification system would reduce 62 radionuclides to safe or non-detectable levels and that only traces of tritium, a radioactive form of hydrogen, and two other isotopes would remain.

多年来，Tepco声称其净化系统将把62种性降低到安全或不可检测的水平，只会残留微量的氚（一种性氢同位）和其他两种同位。
