Abstract

The paper deals with the problem of formation of general procedures for experimental study of environmental impact due to forest fire in complex radiation conditions of fire load formation and its further testing on the example of the ChNPP exclusion zone. The study carried out an experimental verification of the adequacy of the previously proposed methodological apparatus and identified the main directions of its further use as a basis for solving the problems of predicting the negative environmental impact on the environment.

To this end, the following tasks have been solved:the general procedures of the methodology of experimental study of environmental impact due to forest fire in complex radiation conditions of fire load formation are formulated; a comprehensive experimental study was carried out using the developed method on the example of the fire load of the Chernobyl exclusion zone.

Conducted studies in the field indicate that the content of radioactive smoke in the ground atmosphere of the Exclusion Zone can be dramatically increased by several orders of magnitude due to forest fires. Short-term (several days) increased content of radioactive combustion products in the surface air can reach the level of radiation hazard for both the environment and directly for the life of the population living in a clean area at considerable distances (up to 30 km along the track axis) wildfire. The fires in the forests contaminated with Chornobyl radionuclide in the western trace due to the loss of TUE are of particular environmental danger, since the presence of plutonium combustion products in radioactive products results in significant dose loads for the environment and the population.

The practical significance of the obtained results lies in the possibility of their application for carrying out complex ecological audit of the territory, which is subject to secondary radiation influence both inside and outside the exclusion zone of the Chornobyl NPP.
