to date, epidemiological studies have not found an association between radon in drinking water and cancer of the digestive and other systems.
迄今开展的流行病学研究未发现饮用水中的氡与消化系统及其它系统的癌癥之间有联系。
due to dilution in the air, outdoor radon levels are usually very low.
鑒于在空气中的稀释,室外的氡水平通常很低。
radon comes from radium decay.
氡来自镭的衰变。
radon is a natural radioactive gas that emanates from the ground into the air.
氡是一种放射性的自然气体,从地下散发到空气中。
outdoor radon levels are usually very low.
室外的氡水平通常很低。
radon is a chemically inert, naturally occurring radioactive gas without odour, colour or taste.
氡是一种自然产生的放射性惰性气体,它无色、无味、无臭。
for example, indoor radon exposure was estimated to cause between 3-14 % of all lung cancers in 2004, the second most important cause of lung cancer in many countries.
例如,据估计,2004年肺癌患者总数的3-14%是由室内氡暴露引起的,这也是许多国家第二大肺癌发病原因。
radon levels are usually higher in basements, cellars or other structural areas in contact with soil.
氡水平在地下室、地窖或与泥土接触的其它结构区通常较高。
however, all the scientists agree that more data is necessary to prove that radon levels in water are associated with the possible birth of an earthquake.
不过,所有的科学家都一致认为,需要更多的资料才能证明水中氡的含量和可能发生的地震有关。
building codes should be implemented to reduce radon levels in homes under construction.
应采用建筑规范,在住宅建筑中减少氡的水平。
more recently, researchers have sought to associate electromagnetic fields, the radon or hydrogen content of the soil and seismicity patterns with impending earthquakes.
最近,研究者们试图将电磁场以及土壤中氡和氢的含量与将要发生的地震类型联系在一起。
when inhaled, the radiation exposure from radon may lead to lung cancer.
当吸入之后,来自氡的放射暴露可导致人们罹患肺癌。
overall, reducing radon exposure is an important contribution to the goal of good quality indoor air.
在总体上,减少氡接触对实现优质室内空气的目标具有很重要的作用。
these sources of water normally have much higher concentrations of radon than surface water from rivers, lakes and streams.
这些水源通常比河流、湖泊和小溪的地表水具有高得多的氡浓度。
two other air pollutants require some mention: radon and asbestos.
另外两种空气污染需要某种提示:氡和石棉。
although the easier ionization of radon leads one to expect the most extensive chemistry for that element, the high instability of even the most stable isotope has severely limited studies of it.
氡容易离子化,这让人期望,该元素有最广泛的化学反应,但是,这个元素最稳定的同位素也极不稳定,这使氡的研究受到了严重的约束。
the pair used a signal-processing technique called the radon transform to create spectrograms of a variety of audio clips, each just half a second long.
二人使用一种被称为氡变形的单处理技术创造出多种音频片段组成的声谱图,每种只有半秒长。
radon is the second most important cause of lung cancer in many countries.
在许多国家中,氡是肺癌的第二种最重要病因。
the dose-response relation is linear – i.e. the risk of lung cancer increases proportionally with increasing radon exposure.
剂量反应关系是直线的,这意味着肺癌风险与氡接触量的增加成正比上升。
