In-depth elemental analyses of large objects by using brilliant gamma beams
and nuclear resonance fluorescence (NRF):
Two experimental methods will be carried out:
• Self-absorption/Transmission NRF (proposed by Bertozzi1 in 2005)
Main interest in SNM control management Witness foil = enriched sample containing the isotope of interest
