Development of Unified Approaches to Determining Forecast Levels of Cesium-137 Content in the Main Tree Species (UDC 630.62:539.163)

Automatic translation: Within the framework of the National Strategy for Sustainable Socio-Economic Development of the Republic of Belarus for the period up to 2020, one of the directions is to increase the use of local types of fuel and energy resources, and in particular wood fuel. To ensure the radiation safety of the population when handling wood, the content of cesium-137 in wood fuel (firewood) should not exceed 740 Bq / kg - the permissible level established in the Hygienic Norms GN 2.6.1.10-1-01-2001 ''Republican permissible levels of cesium-137 in wood, products from wood and wood materials and other non-food products of forestry'' (RDU / LH-2001). In order to reduce the likelihood of the formation of ash waste with a specific activity of cesium-137 of 10 kBq / kg and more (the level of withdrawal, NRB-2012) at industrial heat supply and wood-fueled power plants with a capacity of more than 0.1 MW, it is proposed to use wood with a cesium-137 content not exceeding 200 Bq / kg. The control level for wood fuel of 200 Bq / kg was adopted in most of the leshozes, with the exception of the five most "polluted" leshozes of the Gomel and Mogilev GPLHOs.
