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.
