It adds that the existing treated wastewater still contains other radionuclides and needs to be further purified.

报告还称，现有经过处理的污水中仍含有其他放射性核素，需进一步净化处理。

In five years, the radionuclides sink five centimeters into the contaminated soil.

五年内，放射性核种在污染土壤里下沉了五公分。

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

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

It still contains a potentially harmful radionuclide called tritium.

它仍然含有一种潜在有害的放射性核素，称为氚。

A water treatment system removes radionuclides and reduces radioactivity.

水处理系统去除放射性核素并降低放射性。

Every time a nuclear weapon goes off - which happens more often than you think - it spreads radionuclides.

每次核武器爆炸——这种情况比你想象的更频繁——它会传播放射性核素。

A radionuclide cystogram uses a similar procedure as the VCUG, except that it uses a radioactive tracer injected into a blood vessel.

放射性核素膀胱显像和VCUG的过程相似，只不过需要静注放射性示踪剂。

It is possible that the composition of the radionuclides are proving more dangerous to the Fukushima birds than they are to the birds near Chernobyl.

也许是因为福岛的放射性核素成分对鸟类更危险。

Melted nuclear fuel debris inside the damaged reactors is being cooled by pumped-in water, which comes into contact with a toxic cocktail of radioactive substances known as radionuclides.

受损反应堆内的熔化核燃料残渣通过注入的水进行冷却，这些水与一系列有毒的放射性物质（即放射性核素）接触。

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.

多年来，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的水平，只会残留微量的氚（一种放射性氢同位素）和其他两种同位素。
