The objective of the present study was to develop the standardized approach to the evaluation of the character of injurious exposure with a view to objective interpretation of the conditions of injury formation and the properties of the traumatic agent. The main attention was given to such parameters of the injurious exposure as loading conditions (mass, speed, direction) and the surface properties of the traumatic agent (area, shape, hardness). It is expected that the use of the proposed system for the evaluation of the injurious exposure in the practical work of forensic medical experts will enhance the reliability of their conclusions and help to avoid mistakes.

This paper is concerned with the topical problems of forensic medical diagnostics of acute radiation injury. The general and specific problems pertaining to the organization and performance of forensic medical expertise of the corpses of persons deceased by reason of acute radiation sickness are considered. The special emphasis is laid on the selection of autopsy materials and their referring to specialized laboratories for the additional investigation. The methods of anti-radiation protection of the medical personnel are considered.

It is generally accepted that an optimal control group for pathomorphological studies of the heart should be constituted by individuals who died from a craniocerebral injury without near-death experience. Polarization microscopy is a principal tool for the assessment of pathomorphological characteristics of myocardium. The presence of ethanol in the blood of a dead individual is associated with enhanced permeability of vascular walls, venous plethora, sludge phenomenon, microcirculatory thrombosis, perivascular and intermuscular oedema but does not on the whole interfere with the objective evaluation of microscopic images of the cardiac muscle.

Mathematical modeling of postmortal themperature used at present for definition of prescription of the death is shown in the article from a position of theory ofprobablibistic functions. Accuracy of examined techniquies is analized by comparison of modeled temperatures with real, fixed by the authors on a material of 158 expert supervisions. The conclusion about inadmissibility of practical use of some mathematical expressions is made in connection with low accuracy of the mathematical device used in them.
