Precise radiocarbon dating of conserved archaeological woods

用来保存受涝木材的材料，如聚乙二醇酯和乳糖醇，会污染木材的放射性碳年代。为了揭示保存木材的精确放射性碳测年能力，对木材样品进行了放射性碳测年处理。结果表明，碳污染干扰了准确的测年。用Py-GC/MS对污染物进行了检测，结果表明Py-GC/MS有可能用于放射性碳测年。

Conservation material such as PEG and lactitol used for preservation of waterlogged woods will contaminant radiocarbon dates of the woods. In order to disclosed capability of precise radiocarbon dating of the conserved woods, the wood samples were treated and dated by radiocarbon dating. As the results, carbon contamination which disturb precise dating was slightly observed. The contamination was also detected by Py-GC/MS. This result imply that Py-GC/MS has a possibility to detect the contamination for radiocarbon dating.
