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, but right now I got bigger problems on my hands.
当然我也可以想成,其实我很暖和,是因为我身后有跟着一个正在衰变的放射性同位素,但现在我手头有更大的问题。

The meteorite, which recently fell to the tropical island in Pacific Ocean, proved to be the present well of the thinnest radioactive isotope!
最近落到在太平洋的热带岛陨石证明是最薄的 放射性的 同位素的现在井!
放射性同位素指有放射性的同位素。 放射性同位素的原子核很不稳定,会不间断地、自发地放射出射线,直至变成另一种稳定同位素,即“核衰变”。
