A dh spokesman said information from the hpa has so far indicated that the risk of having been exposed to po - 210 remained low 生署发言人表示，跟据英国生防护局的资料，公众人士受到钋- 210照射的风险相当低。
The recent death of a russian ex - spy in britain has been linked to the presence of a radioactive polonium - 210 in his body 最近一名俄罗斯前特工在英国中毒身亡，该事件被指与在死者体内发现的放射性钋元素有关。
The hpa appeal was made after the death of a man who might have been exposed to the radioactive material called polonium - 210 po - 210 英国生防护局是鉴于一名男子因接触过一种名为钋- 210的放射性物质后死亡而发出是项声明。
The element was discovered by mr . and mrs . curie in 1898 and was later named after mrs . curie s homeland of poland latin : polonia 1898年居礼夫妇在处理铀矿时发现钋元素，她为纪念自己祖国波兰拉丁文: polonia ，把这种新元素定名为钋。
That compresses the plutonium while it is simultaneously bombarded with neutrons from a trigger made of polonium , and thus begins the second stage 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。
Polonium - 210 , a naturally occurring isotope of polonium , is found in all environmental media , such as in soil , air and even in human body , at very small amounts 钋210是钋元素的一个同位素，在所有自然环境中，例如泥土大气以至人体都可以找到极少量钋210 。
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 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。

We found that pitchblende contains at least two radioactive materials , one of which , accompanying bismuth , has been given the name polonium , while the other , paired with barium , has been called radium 我们发现沥青铀矿物中至少含有两种放射性物质：与铋伴生的命名为钋，与钡伴生的命名为镭。
Polonium - 210 can be used to eliminate static electricity in machinery , remove dusts from photographic film and camera lens , and provide heat energy for thermoelectric power devices in space applications 钋210可消除机器所产生的静电去掉照片底片和摄影机镜头上的污尘及在太空工业上为恒温发电机提供热能。
