Abstract
Technological methods for preparing geospatial data for assessing the radioecological situation and visualizing the results using geographic information system (GIS) software packages are presented in the article. The current levels of soil l37Cs contamination density within the grid of forest quarters of the reserve are given. The article emphasizes that the current levels of radiation contamination in the reserve have an irregular distribution. In this work, the procedure for data preparation was developed and technological methods were tested to assess the current state of the radioactively contaminated territory by forest quarters. The interpolation method was used to eliminate unevenness in the mapping layer of the source data. Radioecological zoning of the territory based on the density of soil contamination with l37Cs for 2023 was carried out to determine the suitability of the territory for the implementation of forest protection measures. Critical areas that generate hazardous levels of dose load for the employees of the Reserve were identified on the maps. The spatial distribution of forest fallout density was calculated. The spatial distribution of radiation contamination of timber and flammable fuel material within the forest quarters of the reserve was estimated. The analysis of the current radioecological situation for the territory of the Drevlians Reserve showed the effectiveness of using modern ArcGIS and MapInfo software packages. Such software combines the following capabilities: preparation of information matrices for calculations and interpolation, in case of limited input data, grouping and classification by values, formation of thematic data sets for storage and further display of results on map schemes.
Keywords: Drevlians Nature Reserve, geosystem analysis, radiation status, radioecological criticality of forest plantations.
