The Reacting of Gun Shot Residues in the Dependence on the Gun Barrel Lenght

Currently, the study of gun shot residues constitutes a wide and a very interesting problem as from the shooter´s view so as from the design enginneers´ view and furthermore possibilities, which infuence the conditions of the products formation process. Currently, one direction of the investigation of gun shot residues proceeds the study of morphology and thereby even possibilities of improvement of frm particles and further physical conditions, which infuence for instance on their stability in the surveyed environment or scatter particles. This problem is investigated by research police institutes above all. The detection of the shot place from the specifc cartridge of a concrete weapon is the objective of their investigation. The lay formation of gaseous gun shot residues and their possible toxicity is interesting from the gunner´s view. We have been dealing with this problem for 5 years. This research paper is intented the problem of the dependence of composition of gaseous gun shot residues on the gun barrel lenght.
