[The use of emission spectrum analysis in the forensic medical expertise of gunshot wounds (experimental research)]. / Primenenie émissionnogo spektral'nogo analiza pri sudebno-meditsinskoi ékspertize ognestrel'nykh povrezhdenii (éksperimental'nye issledovaniia)]

Presents the methodology of experimental shots from various guns (n = 11) by common cartridges and of emission spectral analysis (ESA) which was used to study the regularities in deposition of "gunshot metals" at the site of gunshot injuries and to detect the characteristic differences in shooting with and without obstacles. Effects of some factors on deposition of metal components of gunshot products at the site of gunshot injuries are studied: type of gun, shell (with/without coating or semicoated), presence of obstacles, distance, and order of the shot. Results of studies are presented for some guns, which may be useful in forensic medical expert evaluations by means of ESA.

[Evaluation of injuries features inflicted by shots from gas guns by emission spectral analysis]. / Ustanovlenie metodom émissionnogo analiza osobennostei povrezhdenii, prichenennykh vystrelami iz gazovogo stvol'nogo oruzhiia.

The authors describe a methodological approach to emission spectral analysis of material evidences aimed at evaluating the regularities of deposition of the shot metals at the site of injuries inflicted by gas guns. Injuries inflicted by gunshots with chemical cartridges and with shot cartridges, with and without obstructions, from different distances have been examined. The detected regularities may be useful in forensic medical expert evaluations by means of emission spectral analysis in cases with gas gunshots.

Trials of the Russian x-ray fluorescent crystal diffraction scanning spectrometer Spectroscan A01 manufactured by the Spectron firm in St. Petersburg showed its drawbacks which can lead to erroneous interpretation of the results; this does not permit us to recommend this device for practical forensic medical expert evaluations.
