Standard test methods for determining the biobased content of natural range materials using radiocarbon and isotope ratio mass spectrometry analysis 使用放射性碳和同位素比率质谱分析法测定天然材料中生物基含量的标准试验方法
The portion of the shroud used for the radiocarbon dating was from a corner , which would have been handled often , increasing the likelihood of contamination 来自裹尸布一角的部分用作放射性碳年代测定，通常是经过处理的增加了被污染的可能性。
If the coating is of a great enough thickness , according to gove , it would make the fabric sample seem younger than it should be to the radiocarbon method 依照哈里所说： “如果覆盖物有足够的厚度，那么放射性碳测定法会得出比预期年代要晚的结果。 ”
The ancestors of modern man moved into and across europe , ousting the neanderthals , faster than previously thought , a new analysis of radiocarbon data shows 用放射性碳测定年代的一项最新数据显示，现代人祖先进入欧洲并逐渐取代尼安德特人的过程要比传统理论认为的更快。
Using radiocarbon techniques on sediments collected from four rivers , they determined that bacteria may alter riverine carbon , making it indistinguishable from ocean carbon 科学家以放射性碳技术研究收集自四条河流的沉积层，发现细菌可以改变河水里的碳，使它与海水里的碳无法区别。
By examining these samples for the presence of radiocarbon , the developer of a particular drug can see whether the active ingredients are absorbed into the body and , if they are , how long they persist there 通过检测这些对象中放射性碳，特殊药物的研发者可以看到药物有效成分是否被机体吸收，如果是，他们能存在多久。
Archaeologists have not excavated the site in modern times , and there has been no radiocarbon dating , but juval is the nearest place to the hollow where a number of the flowering plants and mosses associated with ? tzi now grow 考古学家直到现代才到那儿发掘，遗址还没有碳14定年，但是，许多与奥兹有关的开花植物与藓类，现在都在居佛生长，在发现奥兹的地点周围，有这种特徵的就数居佛最近了。
The bacterial bioplastic coating argument is the strongest , as there have been cases in which ancient textiles have yielded radiocarbon dates much younger than other artifacts in the same sites ? most notably in the instance of mummy 1770 in the british museum , whose bones dated 800 to 1 , 000 years older , according to the radiocarbon tests , than the textile in which they were wrapped 细菌性的“原生体覆盖物”的争论来得更激烈，已经有案例，就是古代纺织品的放射性碳年代测定比其他同样大小的史前器物的年代要晚得多? ?最值得注意的例子就是1770年陈列在大英博物馆的木乃伊，根据放射性碳年代测定，骨骼的年代为800至1000年之久，它们都被包裹着。
Arguments and evidence cited against a miraculous origin of the shroud images include a letter from a medieval bishop to the avignon pope claiming personal knowledge that the image was cleverly painted to gain money from pilgrims ; radiocarbon tests in 1988 that yielded a medieval timeframe for the cloth ' s fabrication ; and analysis of the image by microscopist walter mccrone , who concluded ordinary pigments were used 争论和证据却与裹尸布的神奇起源相反，包括一封中世纪的主教写给教宗阿维尼翁的信，声称肖像是有人运用容貌知识聪明地印上去，为了从朝圣者身上获得金钱； 1988年，碳的放射性同位元素测试得出这是一块中世纪时期制造的伪造物；分析肖像的显射镜技术人员沃尔特指出，这只是使用了一种平常的颜料。
