Description: This article deals with the problems of non-liquid methods of decontamination, detailed analysis of these methods of decontamination of weapons, military equipment and military objects. Characteristic features of the liquid-free decontamination of weapons, military equipment and military objects as deactivation by a gas (air) jet are analyzed. abrasive blasting, deactivation by dust extraction. On the basis of the study, the following is suggested: when decontaminating stool gas (air) - the first stage of the process in the event of the removal of structured RA contamination, the second stage of the decontamination process is associated with the removal of RA contaminations that have lost contact with the surface of the object and prevention of possible secondary RA contamination ; when abrasive blasting - the possibility of improving the efficiency of the treatment is based on the use of an air jet after the introduction of a powder having an abrasive action and capable of removing the upper contaminated layer, while deactivation by dust extraction - deactivation based on a closed cycle. The necessity of using these methods of nonliquid decontamination in the cases of the restoration of combat capability of units.
