title: [A micro copper analysis with dithiooxamide as the basis of a new method of the determination of gunshot firing distances (author's transl)].
abstract: The determination of gunshot firing distances up to 160 cm is possible by means of a simple micro copper analysis. From a comparison of accurately known standards with the results from spot analysis by dithiooxamide it is possible to make, without additional instrumentation, a semiquantitative estimation of the copper content. The copper powder from bullet reaching the target is a function of muzzle to target distance. The experiments where analysed by flying spot densitometrie with a TLD 100 and the scatter of the data was determined statistically. This enables the method to a applicable in a very accurate way. The limitations of the method and possible perturbations are discussed and the results from this work are compared with the data obtained by other authors and by different methods.
