Litvinenko was poisoned by tea laced with radioactive polonium-210 at a restaurant in London.

由于钋本身稀有且所过之处留下的放射可被追踪（另见他文），应该能成为发掘信息的线索。

The polonium itself, with its rarity and trail of irradiated locations (see article) ought to be a telling clue.

居里夫人是一位具有化学专门知识的物理学家。1898年，她在法国巴黎发现了放射性物质的镭和钋。

在开始讨论这次演讲的话题之前，我还想回忆一下，镭和钋发现是皮埃尔·居里与我合作完成的。

Before broaching the subject of this lecture, I should like to recall that the discoveries of radium and of polonium were made by Pierre Curie in collaboration with me.

这个过程能压缩钚，并与此同时钚也会受到由钋组成的触发器散发出的中子的轰击，这样就引发了第二个阶段。

That compresses the plutonium while it is simultaneously bombarded with neutrons from a trigger made of polonium, and thus begins the second stage.

A sealed capsule of polonium exploded in her laboratory and her death from leukaemia a decade later, in 1956, was attributed to the accident.

钋- 210是自然存在的物质，但科学家们说，利特维年科一案中发现的高浓度显示，是核反应堆、或者是例子加速器生产的。

Polonium-210 occurs naturally, but scientists say the high concentrations found in the Litvinenko case indicate production at a nuclear reactor, or a particle accelerator.

伟大无私的她、谦虚质朴的高尚品格，坚毅刻苦、锲而不舍的顽强精神，她发现了两种元素——钋和镭，她一生获得了两次诺贝尔奖。
