曝露

Acetone has been in common use as a solvent and as an extracting regent, in industry for several decades. It is easy to evaporate in air. When the concentration of acetone in air is higher than 10,000 ppm, people may experience such symptoms as cephalalgia, nausea and so on.

由於丙酮是工业上广泛应用的溶剂，它极易挥发，且当人体曝露在高浓度的丙酮下，会有头痛、困倦及呕吐等症状，所以丙酮感测器可应用於工业的环境检测。

Every cloud, however, has a silver lining, for it was this strange side effect that gave a team of researchers at the Massachusetts Institute of Technology their crucial idea: stamp-sized patches, much like litmus paper, that change colour when exposed to the urine of people with traces of medicine in their systems.

然而，每一片乌云都有一线希望，因为正是这种奇怪的副作用启发了麻省理工大学的一个研究团队，让他们产生了一个重要的思想：类似邮票大小的一小块补丁，很像石蕊试纸，当人体内有药物成分时，试纸曝露在人的尿液里就会改变颜色。

"In this study, antepartum dental radiography in pregnant women was associated with an increased risk for a LBW infant, especially a TLBW infant," the authors write."Since women may not always be aware of their pregnancy status, it may not be possible to eliminate all dental radiography during pregnancy, but if this goal could be achieved and if the identified association is causal, the prevalence of TLBW infants could be reduced by up to 5%.... The notion that very low-dose radiation exposures to nonreproductive organs in expectant mothers are safe needs to be investigated further."

研究人员表示，在这项研究中，怀孕期妇女分娩前牙科X光摄影与LBW新生儿的风险增加联结在一起，特别是TLBW，由於妇女不能总是注意到她们的妊娠状态，也不可能在怀孕期间取消所有的牙科X光摄影，但如杲这个目标能达成，而且被识别的联想是偶然的，则TWBL新生儿的盛行率能依5%减少；此外，在妊娠妇女中，对非生殖器官极低剂量辐射曝露，是须进一步研究的安全需求概念。
