Long-term behaviour of Cs-137 in spruce bark in coniferous forests in the Czech Republic

Popis výsledku v původním jazyce

Activity concentrations of Cs-137 were detected in more than 400 outer spruce bark samples collected at sites variably affected by Chernobyl fallout across the Czech Republic in 1995 and 2010. The temporal changes in the Cs-137 activities were found. Themean effective half-life (T-EF) for Cs-137 in spruce bark was 9.6 years, and the mean environmental half-life (T-E) was 14 years. The effective half-lives were significantly higher in areas with higher long-term annual precipitation sums. Coefficient ain linear regression y = ax + b of half-lives on precipitation sums was 0.015 y mm(-1) for T-EF and 0.036 y mm(-1) for T-E. The aggregated transfer factor of Cs-137 from soil to bark was determined and the pre-Chernobyl bark contamination related to year2010 was estimated.
