Mushrooms and soils collected from pine forests in izrnir, Turkey were measured for radiocesium and stable Cs in 2002. The ranges of Cs-137 and stable Cs concentrations in mushrooms were 9.84 +/- 1.67 to 401 +/- 3.85 Bq kg(-1) dry weight and 0.040 +/- 0.004 to 11.3 +/- 1.09 mg kg(-1) dry weight, respectively. The concentrations of Cs-137 and stable Cs in soils were 0.29 +/- 0.18 to 161 +/- 1.12 Bq kg(-1) dry weight and 0.14 +/- 0.004 to 1.44 +/- 0.045 mg kg(-1) dry weight, respectively. Even though different species were included, the concentration ratios of Cs-137 to stable Cs were fairly constant for samples collected at the same forest site, and were in the same order of magnitude as the Cs-137 to stable Cs ratios for the organic soil layers. The soil-to-mushroorn transfer factors of 137Cs and stable Cs were in the range of 0.19-3.15 and 0.17-12.3, respectively. The transfer factors of Cs-137 were significantly correlated to those of stable Cs. (C) 2006 Elsevier Ltd. All rights reserved.
