ABSTRACT

Paper describes the problem of modeling radiation impact on personnel, population, and the environment in accidents and incidents with spillage of liquid radioactive media (LRM), which includes the process of evaporation of radioactive substances, transport of radionuclides within the emergency room, the dynamics of air emissions and the impact of pollution on certain categories. Shows the analysis of mathematical and software tools for modeling the consequences of radiation accidents and incidents with the spill of LRM among which the RODOS decision-making system deserves special attention. Developed the mathematical model of emission source characteristics, which includes the instantaneous volume concentration of radionuclides in the air of the process room and the atmospheric emission power, which characterize the emergency situations with the LRM spill. Proposed to improve the process of data preparation for modeling radiation accidents taking into account the spillage of LRM in order to further integrate the developed tools into the decision-making system of RODOS.

KEYWORDS
