It begins to decay and emit positrons, aka, anti electrons.

Kara, we calculated the rate of radioactive decay.

Stars will die out after a few trillion years, protons will decay and matter will dissolve after a thousand trillion trillion trillion years, black holes will evaporate after 1092 years, and then all will be dark.

恒星会在几万亿年后消失，质子会衰变，物质会在一万亿万亿年后溶解，黑洞会在1092年后蒸发，然后一切会变暗。

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·索迪同事一起，发现很少物质里就储备着巨大能，地球大部分热自这种储备放射衰变。

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

当放射性元素衰变时， 单个原子分裂成个原子，但当这种情况发生时， 反应过程中也会释放能。

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，放射性衰变和半衰期，如果你...如果你喜欢高等物理或化学话会明白。

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.

然而其他类型不含希格斯粒子亚原子衰变过程也能够精确地产生相同最终观测结果，就跟缺失希格斯粒子预定产生一般。

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.

布里斯托尔大学亚历山大·法恩斯沃思博士说，钚是一种放射性元素，会随着时间推移而衰变，因此可能不会在数百万年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.

条带年龄可以通过分析其中放射性同位素确定，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细菌，从岩石放射性衰变中获取能，生物需要氮。

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.

但放射性衰变产生热在固体岩石中移动速度很慢，将放射性考虑在内，只能使 Kelvin 估计值提高… … 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，这些核素衰变率表明，岩石在全新世时代并没有暴露出。
