Over the years, scientists have analysed these meteorites and determined their age through radioactive dating.

近年来，科学家们分析了这些来物通过放射性同位素衰减测其年龄。

Using radioactive isotopes, scientists discovered that trees share water and nutrients with others in need.

The other option is radioisotope decay, which uses a substance such as polonium-218 to heat and evaporate a liquid.

另一个选择是放射性同位素衰变，即利用一种物质，如polonium-218，加热液体。

One fossil is a reasonably complete, though fragmented, skull. Radioisotope dating shows it is 170,000 years old.

有一块化石是相当完整的头骨，虽然有裂痕。放射性同位素年份测定显示它有17万年的历史。

Another application is things like radio isotopes for medicine.

另一个应用是用于医学的放射性同位素。

These are radioactive isotopes, atoms with an unusually high amount of nuclear energy.

这些是放射性同位素，具有异常高的核能的子。

On my 12th birthday, I really wanted a titanium centrifuge so, you know, I could separate radioactive isotopes. Of course.

我12岁生日时非常想得到一个钛金属离心机，我就能分离放射性同位素了。当然。

That's why radioactive isotopes spontaneously decay and eject subatomic particles and radiation in the process.

这就是放射性同位素自衰变在此过程中喷射出亚子粒子和辐射的因。

这种影响将氧 18 转化为氟 18，这是一种可以在 PET 扫描中检测到的放射性同位素。

Also, I should note that some radioactive isotopes like carbon-14 in the atmosphere are constantly being renewed by cosmic rays.

另，我应该注意到大气中的一些放射性同位素， 如碳 14，不断被宇宙射线更新。

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

条带的年龄可以通过分析其中的放射性同位素来确定，尤其是铀及其衰变产物。

And sure, I could choose to think about the fact that I'm warm...Because I have a decaying radioactive isotope riding right behind me.

当然了，我也可以想到，我之所以不冷了是因为我正在受到后面放射性同位素热电机的辐射。

They're Radioactive (a tiny bit): Bananas contain a small amount of potassium-40, a naturally occurring, mildly radioactive isotope of potassium.

7. 它们具有放射性（一点点）：香蕉含有少量的钾 40，这是一种天然存在的轻度放射性钾同位素。

I get it. RTGs are good for spacecraft, but if they rupture around humans...no more humans. Which is why we buried it when we arrived.

放射性同位素热电机对航天器是好东西，但要是泄漏了，附近的人类就连渣都不剩。所以一着陆我们就把它埋了起来。

The main heat sources were the electrical heat from spacecraft components and waste heat from their nuclear power sources – the Radioisotope Thermoelectric Generators.
