Application of internal mono standard neutron activation analysis method in elemental analysis of car glasses for forensic study

The use of nuclear techniques for elemental analysis has been successfully developed in many laboratories in the IAEA Member States, including Vietnam. Nuclear techniques have also been proven to be extremely powerful in provenancing samples relevant to forensics. In the framework of the CRP project on Enhancing Nuclear Analytical Techniques to Meet the Needs of Forensic Sciences (IAEA CRP F11021), a total of 19 elemental concentrations in 48 car glass samples has been determined by the internal monostandard neutron activation analysis (IM-NAA) method. In this work, obtained results from the statical analysis indicated that rare earth elements (La, Ce, Sm, Eu, Tb, Yb), transition (Sc, Mn, Fe, Co, Zn) and major (Al, Na, Fe, Ca) elements play a significant role in the group study of car glasses.
