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

一些核弹元素，比如放射性氢，会随着时间流逝而生锈，一定要翻新才能用。

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。

Tritium is an isotope of what element? - Hydrogen.

氚是哪个元素同位素 -氢。

They say tritium is not considered harmful in small amounts.

他们表示，少量氚不被认为是有害。

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。但如果你真想尝一些重水，只要确保我们指是重水而超重水——这不会致命。

The concentration of tritium released is set to come under the World Health Organization's regulatory limit, but such assurances have not been enough to assuage the fears of many in Japan and around the region.

释放氚浓度将低于世界卫生组织监管限制，但这样保证还不足以缓解日本和该地区许担忧。

Tepco said for years that its purification system would reduce 62 radionuclides to safe or non-detectable levels and that only traces of tritium, a radioactive form of hydrogen, and two other isotopes would remain.

来，Tepco声称其净化系统将把62种放射性核素降低到安全或不可检测水平，只会残留微量氚（一种放射性氢同位素）和其他两种同位素。

Professor Suchana Chavanich at Chulalongkorn University in Thailand says no matter the amount, tritium in the discharged Fukushima water can cause mutations in both marine organisms and humans in the long term.

泰国朱拉隆功大学 Suchana Chavanich 教授说，无论泄漏福岛污水中氚含量有少，长远来看，都会导致海洋生物和类发生突变。

The International Atomic Energy Agency (IAEA) said in its report that the treatment process can't remove all radioactive material, and tritium can't be removed at all.

国际原子能机构（国际原子能机构）在其报告中表示，处理过程不能去除所有放射性物质，尤其是氚根本无法去除。

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

东京电力公司和政府官员说，氚——氢一种放射性形式——是唯一不能从水中去除物质。

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，少量氚对类无害，而且世界各地许核电站都会定期放出氚。

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，还含有一些放射性物质。

Before being released, the water is filtered to remove isotopes, leaving only tritium, which is difficult to separate.

在排放污水之前，水经过过滤以去除同位素，只留下难以分离氚。

A level of the hydrogen isotope called radioactive tritium will remain in the water.

一种被称为放射性氚氢同位素会留在水中。

The agency says tritium cannot enter the body through human skin.

该机构表示，氚不能通过体皮肤进入体。

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

与氢或重氢相比，它还含有氚——氢一种同位素，含有两个中子，具有放射性。

It's uncertain whether the ALPS can remove tritium, carbon-14 and other radionuclides effectively based on past experience, Deng said.

邓说，根据过去经验，ALPS 能否有效去除氚、碳-14 和其他放射性核素还不确定。

Tritium is present there in a very, very low concentration.

氚浓度常常低。

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

Plant operator Tepco said the levels of tritium in the water are weakened to below official limits.

核电站运营商东京电力公司表示，水中氚含量已降至官方限值以下。
