| Research Abstract |
It has been considered impossible to perform high accuracy radiocarbon(^<14> C) dating on wooden cultural properties when they were treated for preservation with any kinds of drugs that contain foreign carbon. We focused on removing chemically conservation drugs, such as PEG, from wood properties as completely as possible, and on measuring^<14> C dates accurately on them. Up to now, we could not establish a perfect method to eliminate PEG from wooden properties. However, if we can estimate the amount of PEG still remaining in the samples, we are possible to get aprecise^<14> C age of the wood sample by correcting the^<14> C age for the effect of the remaining PEG amount.
