An urgent and unsolved part of the problem of humanitarian demining of radiation-affected areas by specially trained specialists is the scientific and methodological apparatus of substantiation of standards for assessing the level of preparedness of explosive ordnance disposal (EOD) technicians for putting on a set of armour and radiation protection equipment. According to the results of an experimental study, the authors established that the change in the time of putting on a set of armour and radiation protection equipment is exponential depending on the level of readiness of EOD technicians preparing for humanitarian demining in a radiation-contaminated area. The experiment participants put on a set of armour and radiation protection equipment consecutively for six days (one attempt each day). It is worth noting that with a significance level of a = 0.05, starting from the third attempt, the time EOD technicians put on armour and radiation protection equipment can be considered constant. Based on the experimental results obtained in the third and fourth attempts, we developed standards for assessing the level of preparedness of EOD technicians of the State Emergency Service of Ukraine for putting on a set of armour and radiation protection gear. For this, we used an adapted statistical method for substantiating the standards, which featured the use of weighted average estimates of the fractions (frequencies) of the performance time that fall within the intervals of the excellent standard, as well as between the ‘excellent’ and ‘good’ and ‘good’ and ‘satisfactory’ standards. We determined that for the case of a combination of an L-1 protective suit, armour protection such as a protective vest of the IV protection level, an armoured helmet of the III-A protection level, and a filter gas mask of the GP-5 type, the time for executing this operation could be estimated starting from the third attempt using the following standards: ‘excellent’ – 155 seconds, ‘good’ – 185 seconds, and ‘satisfactory’ – 220 seconds.
