Age assessment of ivory by analysis of 14C and 90Sr to determine whether there is an antique on hand

Zusammenfassung

A method is described to determine whether an elephant has died before 1955 or not. This is accomplished by determination of the radionuclides C-14 and Sr-90 in artifacts made of ivory. The reliability of this method is considerably increased by double nuclide analysis and therefore is applicable for judicial expert opinions. (C) 2010 Published by Elsevier Ireland Ltd.
