Detailed protocol for an accurate non-destructive direct dating of tooth enamel fragment using Electron Spin Resonance

Joannes-Boyau R.

In the context of human evolution, fossil remains are too valuable to be destroyed and any alteration should be kept to a minimum. The newly developed protocol on fossil fragments has open the gate for ‘virtually’ non-destructive ESR (Electron Spin Resonance) direct dating of human re-mains. The method allows the separation of unstable and interfering signals that were responsible for large dose underestimation. While a complete investigation of the ESR signal remains a complex task and requires numerous hours of manipulations, a rapid dose assessment protocol can be achieve with-out compromising the accuracy nor the integrity of the sample. The new protocol should be used for future dating regardless of the possibility of measuring powder.
