A radioactive isotope called tritium will remain in the waste water.

氚这种放射性同位素无法被清除。

Some elements of nuclear bombs, like radioactive tritium becomes stale over time and must be refurbished.

些核弹的元素，比如放射性氢，会随着时间的流逝而生锈，定要翻新才能用。

Instead of hydrogen or deuterium, it contains tritium, an isotope of hydrogen that has two neutrons, and is radioactive.

与氢重氢相比，它还含有氚——氢的种同位素，含有两个中子，具有放射性。

It turned out that the water contains more than tritium, some more radioactive materials that also in the water.

事实证明，污水中不仅含有氚，还含有些放射性质。

Still, there is a form of heavy water you should definitely avoid: tritium oxide, or super-heavy water.

氚氧化，重水。

Experts say tritium is not harmful to humans in small amounts and has been regularly released from nuclear plants around the world.

专家表示，少量的氚对人类无害，而且世界各地的许多核电站都会定期放出氚。

TEPCO and government officials say tritium – a radioactive form of hydrogen – is the only substance that cannot be removed from the water.

东京电公司和政府官员说，氚——氢的种放射性形式——是唯不能从水中去除的质。

Helium-3 is only produced when the tritium in a nuclear bomb decays, and since we're decommissioning more and more nuclear bombs, we're running out of helium-3.

氦-3只在核弹中的氚衰变时才会产生，因为我们在停止使用越来越多的核弹，所以氦-3正在被慢慢消耗。

So, I'm not recommending you do this, but if you really want to test out some heavy water, just make sure we're talking about deuterium oxide, not tritium oxide—it's not going to be a dead person.

所以, 我不建议你这样做。但如果你真的想尝些重水，只要确保我们指的是重水而非重水——这不会致命。
