Abstract

As a result of the industrial accidents, including the accident at the Chernobyl nuclear power plant, a significant part of forests of the country was subjected to radioactive contamination. The use of wood from these regions is very important as it allows solving the environmental problems by reducing the probability of recontamination of surrounding areas with radionu-clides. This problem can be fixed on the basis of the processing technology of wood con-taminated with radionuclides with the use of mobile units in the felling sites operated from gasoline or diesel engines via the driveshaft. This enables to avoid transportation of contam-inated wood in the clean regions, to organize the processing without the stationary plant constructions and to reduce the cost of processing. To implement such technology we offer the cutting schemes for wood, contaminated with radionuclides, which allow obtaining sawn timber of desired size, not containing radionuclides. This solves the problems of optimal planning of log cutting of various diameters by including only those sawing patterns in the optimum cutting plan that provide the desired size of sawing lumber with the permissible content of radionuclides at the lowest raw-materials consumption. This technology provide with minimal losses harvesting and shipping to a consumer of "clean" wood in the form of debarked raw material or finished lumber. The products, which eliminate a direct contact with people, such as sleepers, make the most sense. The resulting radioactive waste wood can be disposed by shredding and landfilled directly in a felling site or by the gasification methods using a gas generator producing mixture gas with a minimum level of radionuclide contamination
