title: Children and guns: The detection of recent contact with firearms on children's hands by the PDT reagent.
abstract: Throughout the world, young children are worryingly found to be involved in both unintentional and intentional gun violence, rendering the forensic investigation of gun handling by children a highly important matter. The effectiveness of the PDT reaction for mapping iron traces on hands of children has been tested and compared to its application on adults. Counter-intuitively, children were found to produce considerably more intense PDT impressions than adults. A plausible explanation which is based on physiological differences between children and adolescents is suggested.
