“…Mean activities of 137 Cs in contaminated pine wood in Zhytomir region located in the north part of the Ukraine ranged from 900 to 3000 Bq/kg (IAEA, 2006), while radiocaesium specific activities in different compartments of contaminated Scots pine in Gomel district of Belarus varied from 1.8 to 62.4 kBq/kg (Goor and Thiry, 2004). It should be noted that the accepted standard for contaminated firewood utilization is <750 Bq/kg, as an exception, the temporary permissible level for 137 Cs activity concentrations in firewood in Russia is 1400 Bq/kg (Davydchuk, 1999;IAEA, 2006). Nevertheless, about 550,000 tons of firewood from local contaminated forests are annually utilized in 80,000 dwelling houses of rural settlements in Belarus.…”

“…For 137 Cs, this is set at 740 Bq kg −1 in Belarus, Ukraine, and the USSR for domestic use and at 3,700 Bq kg −1 for industrial fuel use (Davydchuk, 1999;Dvornik and Zhuchenko, 1999;Szekely et al, 1994). Exemption limits for use of ashes on gardens for 137 Cs are set at 33,000 Bq kg −1 (Szekely et al, 1994).…”

Field experiments were conducted in the Chernobyl-affected area to assess if short rotation coppice (SRC) for energy production is a feasible alternative for contaminated land. Four willow clones were planted on sandy and peaty soil and the radiocaesium (137Cs) and radiostrontium (90Sr) transfer factors (TF) and yield relevant parameters were recorded during four growing seasons. The 137Cs and 90Sr soil-to-willow wood TF on sandy soil (second growing season) were on average 1.40+/-1.06 x 10(-3) m2 kg(-1) and 130+/-74 x 10(-3) m2 kg(-1), respectively. The 137Cs TF recorded for the peaty soil (fourth growing season or end of the first rotation cycle) was on average 5.17+/-1.59 x 10(-3) m2 kg(-1). The 90Sr-TF was on average 2.61+/-0.44 x 10(-3) m2 kg(-1). No significant differences between clones for the 137Cs and 90Sr-TF were observed. Given the high TFs and the high deposition levels, Belarus exemption levels for fuel wood were highly exceeded. The annual average biomass production for one rotation cycle on the peaty soil ranged from 7.8 to 16.0 t ha(-1) y(-1) for one of the clones, comparable with average annual yield figures obtained for western Europe. On the sandy soils, first-year yields were 0.25 t ha(-1) y(-1). These soils are not suitable for SRC production and should better be dedicated to pine forests or drought-resistant grasses.

“…In semi-natural ecosystems, the contamination of forest stands with radiocaesium ( 137 Cs, T 1/2 ¼ 30.2 years) is particularly worrying due to large-scale (Izrael et al, 1996) and long-term radiation exposure risks for local populations and forest workers, but also in terms of loss of economic return for the wood industry (Shaw et al, 2001) because of sanitary restrictions applied to contaminated wood use (Tikhomirov et al, 1993;Davydchuk, 1999).…”
