Radon

氡是具有符号Rn和原子序数86的化学元素。它是一种放射性,无色,无味,无味的惰性气体,天然存在,作为铀或钍的间接衰变产物。 其最稳定的同位素,222Rn,半衰期为3.8天。 氡是在正常条件下仍然是气体的最密集物质之一。 在正常条件下,只有放射性同位素的气体也是唯一的,因放射性而被认为是健康危害。 强烈的放射性也阻碍了氡的化学研究,只有少数化合物是已知的。 氡是在正常的放射性衰变链中形成的一个中间步骤,钍和铀通过其逐渐衰变成铅。 钍和铀是地球上最常见的两种放射性元素; 自从地球形成以来,他们已经存在了。 他们的天然存在的同位素的半衰期很长,几十亿年。 因此,钍和铀,它们的衰变产物镭及其朽烂产物氡将因此而继续发生数千万年的浓度。 Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas, occurring naturally as an indirect decay product of uranium or thorium. Its most stable isotope, 222Rn, has a half-life of 3.8 days. Radon is one of the densest substances that remains a gas under normal conditions. It is also the only gas under normal conditions that only has radioactive isotopes, and is considered a health hazard due to its radioactivity. Intense radioactivity has also hindered chemical studies of radon and only a few compounds are known. Radon is formed as one intermediate step in the normal radioactive decay chains, through which thorium and uranium slowly decay into lead. Thorium and uranium are the two most common radioactive elements on earth; they have been around since the earth was formed. Their naturally occurring isotopes have very long half-lives, on the order of billions of years. Thorium and uranium, their decay product radium, and its decay product radon, will therefore continue to occur for tens of millions of years at almost the same concentrations as they do now.

在英语 词典里radon的定义

字典中氡的定义是稀有气体组中无色的放射性元素,其中最稳定的同位素是氡-222,是镭的衰变产物。 它在放射治疗中被用作α粒子源。 符号:Rn; 原子序号:86; 222Rn的半衰期为3.82天; 价态:0; 密度:9.73公斤/立方米; 熔点:-71℃; 沸点:-61.7℃。

The definition of radon in the dictionary is a colourless radioactive element of the rare gas group, the most stable isotope of which, radon-222, is a decay product of radium. It is used as an alpha particle source in radiotherapy. Symbol: Rn; atomic no: 86; half-life of 222Rn: 3.82 days; valency: 0; density: 9.73 kg/m³; melting pt: –71°C; boiling pt: –61.7°C.
