As part of the development and implementation of technogenic risk assessment method, three key tasks were solved: constructing the trajectory of a cloud saturated with vapors of dangerous chemical substance; modeling the dissipation of this cloud; assessing the technogenic risk along the trajectory of cloud movement. The aim of the work is to construct a new numerical method for assessing technogenic risk as a result of wind transport and dissipation of hazardous chemicals. The stages of implementing risk calculation algorithm are shown. The simulation of spatial distribution of dangerous consequences of a conditional man-made event that occurred in the Arctic zone was carried out. It is concluded that the proposed approach can be adapted to the model description of radioactive substances emissions into the atmosphere, environmental pollution of the area as a result of large-scale industrial and geological developments, geodynamic disasters.
Key words: technogenic risk, Arctic zone, modeling, assessment, hazardous chemical, wind transport, wind speed field, cloud movement trajectory.
