Comparative analysis of the regulations of humanitarian demining in a radiation-contaminated area

Abstract

A comparative analysis of the regularities of the implementation of a control typical operation of humanitarian demining in a radiation-contaminated area was carried out by comparing the time of implementation of the method of jerking an anti-tank mine, which is located at a distance of 50 meters from the shelter, where the sapper is located during the execution of the most dangerous stage, in three different options for the use of a complex of means individual protection by sappers of the State Emergency Service of Ukraine under various conditions of possible radiation exposure: a combination of a protective suit L-1, armor protection of the type of protective body armor of the IV level of protection, a protective armor helmet of the level of protection III-A, and a respirator of the type ZM 6200 ffp3; a combination of L-1 protective suit, armor protection of the IV level of protection type protective body armor, III-A level of protection armor helmet, and GP-5 type filter gas mask; a combination of L-1 pro-tective suit, armor protection type IV protective vest, III-A protective helmet, and compressed air apparatus Dräger 7000. This was caused by the fact that an important and unsolved part of the problem of humanitarian demining is the lack of regularities in the operational activity of sappers of the State Emergency Service in conditions of radiation contamination. The uniqueness of the considered situation is that only in Ukraine there is a need for humanitarian demining of radiation-contaminated area. The analysis of the obtained regularities showed that the time of execution of typical operations of the considered process is described by a normal distribution regardless of the combination of personal protective equipment in which sappers work. At the same time, if the time of performing typical operations in a set of protective equipment, which includes an isolating device, differs significantly from their performance in a set that includes a filtering gas mask, then the time of performing it in a set with a respirator of class ffp3 is practically no different from the time of performing it in a set with filter gas mask.
