The validation of the strategy of lumbering and forest restoration works in the forests of Byelorussian Chernobyl zone

The analysis of constituent factors of contamination, influencing the long-term prediction or radiation situation and exposure dose in Belarus forests gives a base for validation of the strategy of lumbering works in the Chernobyl zone. In order to receive more accurate information about effective dose obtained by the forestry personnel involved in felling of forest or in decontamination activity the methodical model based on the Monte-Carlo method was developed and three-dimensional program {open_quotes}FOREST{close_quote} was compiled which reflects the relations between rate of irradiation and conditions of work, and allows to estimate effective dose of the forestry crews depending on type of equipment used, its productivity, method of forest clearing and contamination level. The analysis of conditions of lumbering and forest restoration works demonstrated that at their realization the ratio between productivity of the machines and the scenario of works influence essentially the exposure doses. The method of forest clearing at considered conditions slightly influence the dose received by personnel, and thus, it may not be taken into account.
