This report summarizes the research within the weapons traumatology program during 2005. In the report both the scope and aim of the program is shortly presented. Both national and international aspects are discussed. The research activities are described for each project and results are shortly presented. The research is divided into the following defence related projects: 1/ Biomedical effects of trauma, 2/ Wound ballistics, protection, treatment, 3/ Safety criterion BABT (Behind Armour Blunt Trauma). Project 1/ is part of a 6-nation study dealing with the effects of HPM (High Power Microwave). Dose dependent effects of HPM have been confirmed. The work will continue to find safe levels. Neuro trauma research in project 1/ is focused on early diagnostic methods. The value of small portable digital EEG equipment either as a stand alone unit or used in combination with bio markers have been evaluated with positive results. Within the project effects of non lethal weapons are also studied. Project 2/ is focused on trauma behind body armour, BABT (Behind Armour Blunt Trauma). Research is performed using micro dialysis (MD) technology to look at the metabolism in brain and lungs where the MD-technology has proved its value. Pressure measurements have been performed inside the skull and chest to look at a connection between trauma and fysiological effects. Project 3/ is aiming for a new safety criterion for the evaluation of body armour. The method is based on a new type of technical measurement where results from animal tests can be used for calibration. Within all projects the collaboration between the medical and technical research has been further developed both on a national and international scale.
