Fluorine determination in different types of ivory by PIGE technique

Abstract

Fluorine was determined by particle induced gamma-ray emission (PIGE) technique with 2.3 MeV protons in elephant, mammoth, aquatic (walrus, pot whale, narwhal, hippopotamus) and archaeological ivory, with concentration varying between 55 ppm and 2.3 %. The characteristic variation of F concentration with species shows that it has the potential to serve as a marker in identifying different types of ivory. Additionally, Na concentration was also reported in all the analysed samples.
