Price per Unit: 130 €
Report: IAEA-TECDOC-825
Date of Release: September 1995
IAEA CH 7 (formerly PEF-1) was prepared by H. Gerstenberger and M. Herrmann, Zentralinstitut für Isotopen und
Strahlenforschung, Leipzig, Germany [1,2]. It was checked for isotopic homogeneity and its recommended δ13C value was determined in an international calibration exercise [3].
