核探员:制造核武器的"关键工种"

　　Hutcheon: If you go out on the beach and pick up a handful of sand, it contains about 4 parts per million of uranium.

　　赫琴：如果你到沙滩上抓起一把沙子，这其中就含有大约百万分之四的铀。

　　Nuclear investigative testing is used by agencies such as the United Nations to monitor countries’ nuclear activities such as the production of enriched uranium and their compliance with international agreements on weapons of mass destruction.

　　联合国等机构会利用核侦查测试来监测各个国家的核活动情况，比如浓缩铀的生产以及对国际大规模杀伤性武器协定的履行。

　　Hutcheon: Our charge is to measure the properties of the material and to demonstrate that we can do this with high precision, and that the data we can collect would stand up, for example, in a court of law.

　　赫琴：我们的任务是检测这种材料的属性，并证明我们可以对其进行高精度的检测。我们所能收集的资料可以成为证据——比如在法庭上。
