Retrospective determination of (137)Cs specific activity distribution in spruce bark and bark aggregated transfer factor in forests on the scale of the Czech Republic ten years after the Chernobyl accident
Result description
The (137)Cs specific activities (mean 32 Bq kg(-1)) were determined in spruce bark samples that had been collected at 192 sampling plots throughout the Czech Republic in 1995, and were related to the sampling year. The (137)Cs specific activities in spruce bark correlated significantly with the (137)Cs depositions in areas affected by different precipitation sums operating at the time of the Chernobyl fallout in 1986. The ratio of the (137)Cs specific activities in bark and of the (137)Cs deposition levels yielded bark aggregated transfer factor T(ag) about 10.5 x 10(-3) m(-2) kg(-1). Taking into account the residual specific activities of (137)Cs in bark 20 Bq kg(-1) and the available pre-Chernobyl data on the (137)Cs deposition loads on the soil surface in the Czech Republic, the real aggregated transfer factor after and before the Chernobyl fallout proved to be T*(ag) = 3.3 x 10(-3) m(-2) kg(-1) and T**(ag) = 4.0 x 10(-3) m(-2) kg(-1), respectively.
