Cellulose

​IAEA-C-3 cellulose was prepared by W.G. Mook and J. van der Plicht of the Centre for Isotope Research CIO, University of Groningen, Netherlands. The starting material was produced in 1989 from one season’s harvest of ca. 40‑year‑old trees from Sweden, imported to Netherlands. The trees were chopped and bleached to cellulose at a paper factory in Bergum, Netherlands, and supplied to CIO in sheets. The bulk material of about 1 m3 is kept at CIO, where part of it was cut into 50 gram pieces, sealed in plastic and shipped to IAEA. The recommended value of this quality control material is the result of the statistical evaluation of an interlaboratory comparison [1, 2].
