The most dangerous element that came out of the Chernobyl reactor wasn't cesium or plutonium, but lies.

切尔诺贝利反应炉释出的最危险元素并非铯或钸，而是谎言。

The most widely used atomic clocks use cesium atoms.

最广泛使用的原子钟使用铯原子。

Look what happened when the mother was contaminated with cesium during pregnancy.

看看怀孕妇女遭到铯污染后会有什么影响。

It was made from the cesium that he stole from a dental X-ray machine.

他用从牙科X光机里偷来的铯自己做的。

When microwave radiation is humming at the exact right frequency, it does something special to cesium atoms.

当微波辐射以正确的频率震动时，它会对铯原子产生特殊的影响。

Cesium atoms oscillate at microwave frequencies, and are usually paired with a vibrating quartz crystal to keep time.

铯原子以微波频率振荡，通常与振动的石英晶体配对以计时。

Passed every test except the cesium.

到铯检测时才晚节不保。

So cesium is very likely to give up, it's very likely to give up electrons.

所以铯很有可能放弃，很有可能放弃电子。

And you think you can beat this cesium test?

你觉得你能通过那个铯元素测试？

Cesium was already a popular element for atomic clock research, and by 1968, some cesium clocks were even commercially available.

铯已经是原子钟研究的热门元素， 到 1968 年，一些铯钟甚至可以商用。

Radioactive Cesium 137 and lodine 131 rain down on the south of France and Corsica. Crops and pastures are seriously contaminated.

放射性铯137与碘131 在法国南部与科西嘉倾盆而下 作物与牧草遭到严重污染。

Cesium 137 doesn't exist in nature.

铯137并不存在于自然界。

All that was left was to determine how many ticks of a cesium atom were in a second.

剩下的就是确定铯原子在一秒钟内有多少滴答声。

If we don't, they won't run the cesium test.

如果我们不去，他们就不会做铯元素测试。

These atomic oscillations are so consistent that, in 1967, one second was officially defined in terms of cesium oscillations.

这些原子振荡是如此一致，以至于在 1967 年，一秒被正式定义为铯振荡。

That'll force the auction house to run a cesium test.

所以拍卖行不得不做一个铯元素测试。

And so cesium has one electron in it's outer most shell, in the sixth shell, while, say, lithium has one electron.

所以铯的最外层有一个电子，在第六层，而锂有一个电子。

When the larvae were fed the leaves, mortality and abnormality rates sharply went up at low doses in response to the cesium that they were ingesting.

当幼虫被喂食叶子时，低剂量的死亡率和异常率急剧上升， 以响应它们摄入的铯。

So, you turn the dial on your little radiation machine until you hit the sweet spot that excites the cesium atoms, then you count 9,192,631,770 wobbles of that radiation.

所以，你转动你的小辐射机的表盘，直至到达激发铯原子的最佳位置，然后你计算 9，192，631，770 次辐射的摆动。

We apologize for the delay, but as some of you are aware, we have had to conduct a cesium test to verify the authenticity of the two bottles we have been presented with.

很抱歉耽误这么久 为了万无一失，我们必须进行铯检测来确认这里的两瓶酒是否真品。
