Description: This article discusses the possibility of using that way to improve the non-liquid decontamination method. Such characteristic features as decontamination by removing the contaminated layer and isolating the contaminated surface from samples of weapons, military equipment and military facilities, electronic equipment, electrical devices, roads, terrain, etc., as well as in the absence of the necessary for decontamination, are analyzed water resources. Based on the analysis, it is proposed to distinguish two stages of the decontamination process: the first stage of the process is carried out in case of removal of structured RA contaminants, the second stage of the decontamination process is connected with the removal of RA contaminants that have lost contact with the object surface to prevent possible secondary RA contamination. It is noted that the practical implementation of decontamination by removing the top layer of contaminated soil is associated with high material costs and laborious. When removing a contaminated layer along with RA, a part of the soil itself or material is removed, the mass of which is a thousand or more times greater than the mass of the RA itself. This soil is a source of RA pollution during transportation, as well as along the path of traffic. All those surfaces with which this soil comes into contact are also polluted. In addition, burial sites for contaminated soil are required. Not less problems arise during the decontamination of equipment, buildings and steel structures. In this case, the depth of the removed layer is relatively small relative to the contaminated layer; the mass of the removed contaminated layer is less than during decontamination of the soil. However, the top layer of soil is removed with less effort than the top layer with different materials and equipment. In addition, the elastic properties of the material being removed contribute to a greater spread of this material into the environment and create a greater likelihood of secondary pollution. And decontamination by insulation of the contaminated surface will be effective only in the case when the insulating material can reduce the damaging effects of RA contamination. Usually, the insulating material fixes RA contamination and does not allow it to spread from the contaminated surface, thereby reducing the risk of direct contamination when in contact with these surfaces or is completely eliminated. There remains another, the main danger - the danger of exposure of people. Determined and justified the need to use this method in cases of restoring the combat capability of military units after the conduct of hostilities, both in cases of the use of weapons of mass destruction by the enemy and, especially, after emergency radioactive contamination, as well as during decommissioning of spent nuclear power plants.
