Development of the digital twin to assess current radioecological situation inside the 30-km zone in the area of pilot demonstration energy complex (PDEC) siting

The development of the digital twin for the assessment of current radioecological situation is considered in the paper. For the twin development data of comprehensive radioecological survey in the area of the Pilot demonstration energy complex (PDEC) siting were used. The twin was developed with the use of the ArcMap 10.5 software module, the part of the ArcGis package. The digital twin is a virtual model that describes the real-time radioecological situation inside the 30-km zone of the nuclear object influence using a set of mathematical models and maps. The twin contains information on radionuclides and heavy metals content in the environment, radiation doses to humans and biota. The data contained in the twin were used for preparing and publishing the atlas of the radioecological situation in the 30-km zone of PDEC influence. The results obtained can be used for radiological safety assessment and optimization of radiation monitoring programs for PDEC.
