大气中的低电离能也将是影响的地球放射性排放量，尤其是当X射线辐射工程。
The ionisation of the low atmosphere could also be the effect of the radioactive emissions of the Earth, especially when the X radiation works.
早期地球含有丰富的放射性物质。
因为内核失去在其形成时捕捉的热能，而且是通过内核里的放射性元素产生的热能，所以地球正渐渐冷却下来。
The Earth is growing cooler as it loses the heat trapped in its creation and generated by radioactive elements within it.
当氦衰变成为氦-3相对于我们在太阳里看到的那它就可用了，因为地球上多数的氦-4是通过元素铀和钍自然放射性衰变而造成的。
What helium is available is depleted in helium-3 relative to what we see in the sun, because most of Earth's helium-4 is freshly made via natural radioactive decay of the elements uranium and thorium.
氮是地球大气中最平常的气体，它在核电站中的主要放射性形式被叫做氮16。
Nitrogen is the most common gas in the earth's atmosphere, and at a nuclear plant the main radioactive form is known as nitrogen-16.
他向普渡大学的研究者提出建议：寻找地球上放射性元素衰变速率的变化同太阳自转的关系。
His advice to Purdue: Look for evidence that the changes in radioactive decay on Earth vary with the rotation of the sun.
而竹制玩具则可以减少森林滥伐，并且竹子在收割过程中所制造出的放射性物质极少，几乎为零，所以选择竹制玩具不仅是为宝宝的健康着想，也为我们的地球做出了环保贡献。
Toys made from bamboo also don't contribute to deforestation. Plus, their harvesting process creates little to no emissions, making them healthy toys for your baby and the planet.
这两项相结合，导致了地球上比磁力更大的放射性，而在100年以前还没有这样。
The two combined cause greater radiation upon earth than magnetism when less than 100 years ago this was not so.
它来自星际空间抵达地球的宇宙射线，来自土壤中矿物质的放射性衰变。
It results from cosmic rays reaching the earth from the outer space, and from the radioactive decay of mineral in the soil.
一种可能性就是内部岩石的放射性衰变，地球热量的0.025%来自于这种衰变。
One possibility is radioactive elements decaying inside rocks, which already give the Earth about 0.025 percent of its geothermal energy.
还有一种地球物理勘探仪器，这就是盖格计数器。它用来探查放射性物质的存在。
Still another geophysical device. That is Geiger counter, which detects the presence of radioactive substances.
研究人员发现，在地球传送到大气的热流中，地球内部放射性同位素衰变所产生的热量占了其中一半。
The Earth has cooled since its formation, yet the decay of radiogenic isotopes, and in particular uranium, thorium and potassium, in the planet's interior provides a continuing heat source.
为查明537-1放射性废物库是否发生泄漏，进行了放射性水文地质、地球化学和地球物理等综合研究。
