Methodological Approaches to Selection of Personnel of Emergency Rescue Teams for Liquidation of Consequences of Radiation Accidents

Summary. The aim of the study is to develop methodological approaches and criteria of selection of specialists for participation in the work on liquidation of consequences of radiation accidents as part of emergency rescue formations.

Materials and research methods. Due to the lack of detailed individual medical, psychophysiological and dosimetric data on persons involved in the elimination of consequences of radiation accidents in the available scientific literature, the study was conducted using theories of occupational risks and functional reliability, as well as mathematical modeling of data on the results of health assessment and professional and psychophysiological adaptation of personnel of radiation facilities.

Results of the study and their analysis. A conceptual model and criteria of professional selection of specialists for participation in the work on liquidation of consequences of radiation accidents are proposed for selection of personnel. The criteria include an integral indicator of the suitability level and a probabilistic nomogram determining the acceptable range of its variation. This indicator takes into account accumulated dose load, level of health loss of worker from the impact of life factors and his/her functional reliability. It is proposed to use the data of periodic medical examinations and psychophysiological examinations, as well as individual dosimetry to assess the level of professional suitability. A proposal is made to use the results of the conducted research on assessment of professional suitability to eliminate the consequences of radiation accidents as one of the qualification indicators of workers required for preliminary authorization to work in emergency rescue formations under conditions of planned increased exposure.
