Popis: This work is realized in view to determine appropriate techniques for the revelation of mineral gun shoot residues. Picked up from the crime scene, these indicial traces are used as material proofs for helping and guiding judicial investigations. As achievement of this process, two (02) technics were employed for mineral gun shoot residues, namely; Neutron Activation Analysis, and scanning electron microscopy/EDX. Samples of metallic powder residue were realized after several shoots by different kind of weapons with local and foreign ammunitions. So, this study was undertaken to develop chemical ballistic specialty in order to improve forensic investigations and drive benefit to Technical and Scientific Police of Algeria to be use for judicial investigation. It turns out that the SEM/EDX method is more adequate to this type of investigation, despite the high sensitivity of the NAA. This is stated; NAA remains a complementary methods.
