Radiocarbon Measurements of Paper: A Forensic Case Study to Determine the Absolute Age of Paper in Documents and Works of Art
Published online by Cambridge University Press: 31 October 2017
Abstract
In a case study to assess the possibilities and limitations of determining the exact age of paper, we measured radiocarbon (14C) concentrations in bulk-paper cellulose and starch extracts from 20 known-age paper samples of the last 65 yr. As expected, 14C concentrations in single-seasonal grown starch extracts are in reasonably good agreement with post-bomb atmospheric 14C. In contrast, 14C concentrations in bulk-paper cellulose indicate apparent admixtures of tree-ring fibers spanning up to >50 yr. In a forensic investigation, combining 14C results from single-seasonal components like starch with those from long-lived fibers, could potentially enhance the precision of paper production-date estimates for samples made after 1955.
