Now, as far as radioactive things go, tritiated water is pretty weak.

现在，就放射性物质而言，氚化水相当弱。

Scientists don’t actually have a great sense of how dangerous tritiated water is, they're

科学家实际上并不清楚氚氧化物水到底有多危险。

But because tritiated water is used in nuclear reactors, the real concern is when those reactors leak, or if there's an accident.

由含氚水会用核反应堆，真正值的是如果这些反应堆发生泄露，或出现事故。

由核反应堆中使用了氚化水， 真正令人担忧的是这些反应堆何时泄漏，或者是否发生事故。

Scientists don't actually have a great sense of how dangerous tritiated water is, they're not just like putting it in cups and having people try it, but they assume exposure isn't good.

实际上，科学家们并没有强烈地意识到含氚水有多危险，他们不只是把它放进杯子里，让人们尝尝，还认为与其接触无大碍。
