With a colleague named Frederick Soddy he discovered that immense reserves of energy were bound up in these small amounts of matter, and that the radioactive decay of these reserves could account for most of the Earth's warmth.

他与一位名叫弗雷德里克·索迪的同事一起，发现很少量的物质里就储备着巨大的能量，地球的大部分热量都来自这种储备的放射衰变。

As a radioactive element decays, the individuals atoms split into multiple, but when that happens the reaction also releases energy.

It's the idea that over time we forget things at an exponential rate, sort of like, you know, radioactive decay and half-life if you... if you're into A-level physics or chemistry.

这个想法是，随着时间的推移，我们会以指数速度忘记一些内容，这有点像，你知道，放射衰变和半衰期，如果你...如果你喜欢高等物理或化学的话会明白的。

But other sorts of subatomic process that do not involve the Higgs can produce precisely the same final readings as those the missing boson is predicted to generate.

然而其他类型的不含希格斯粒子的亚原子衰变程也能够精确地产生相同的最终观测结果，就跟缺失的希格斯粒子预定产生的一般。

Dr Alexander Farnsworth, at the University of Bristol, said plutonium is a radioactive element and decays over time, so might not persist over geological timescales of millions.

布里斯托尔大学的亚历山大·法恩斯沃思博士说，钚是一种放射元素，会随着时间的推移而衰变，因此可能不会在数百万年的地质时间尺度上持续存在。

The age of a band can be determined by analysis of the radioactive isotopes within it, particularly those of uranium and its decay products.

条带的年龄可以通分析其中的放射同位素来确定，尤其是铀及其衰变产物。

Living things need nitrogen, whether you're a giraffe or a bacterium living two miles underground gathering your energy from the radioactive decay of rocks.

无论你是长颈鹿还是生活在地下两英里的细菌，从岩石的放射衰变中获取能量，生物都需要氮。

But heat from radioactive decay moves so slowly through solid rock that taking radioactivity into account only improves Kelvin's estimate by...pretty much nothing.

但放射衰变产生的热量在固体岩石中的移动速度很慢，将放射考虑在内，只能使 Kelvin 的估值提高… … 几乎没有提高。

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，这些核素的衰变率表明，岩石在全新世时代并没有暴露出来。
