Abstract

137Cs and 40K concentrations in soil and air were measured since 1986. 137Cs wind-resuspension factor was 7.4 ± 1.3 × 10–6 m−1 after Chernobyl, while one decade later, it reduced to 1.5 ± 0.3 × 10–9 m−1, but for 40K was constant 7.4 ± 1.3 × 10–9 m−1 The air 137Cs-to-40K ratio was 12:7 after the accident, dropping to 0.04 during 1995. The Fukushima accident gave 1.0, which is like a radiological event in Spain when it was 0.6. The Chernobyl wildfires recorded 0.18, while contaminated wood combustion for heating showed 0.15. The results indicate that forest ecosystems remain a source of unwanted radioactivity in the environment.

希腊近40年137cs - 40k比值和风再悬浮因子监测
自1986年开始测定土壤和空气中的137Cs和40K浓度。切尔诺贝利事故发生后,137Cs的风悬浮系数为7.4±1.3 × 10-6 m−1,10年后降至1.5±0.3 × 10-9 m−1,而40K的风悬浮系数为7.4±1.3 × 10-9 m−1,事故发生后空气137Cs- 40K比值为12:7,1995年降至0.04。福岛核事故的得分为1.0,与西班牙的放射性事件的得分0.6相当。切尔诺贝利的野火记录为0.18,而被污染的木材燃烧取暖的记录为0.15。结果表明,森林生态系统仍然是环境中有害放射性的来源。
