Keywords: Soil to mushroom transfer, 137Cs, 40K, Alkali–alkaline earth elements, Heavy metals
Abstract: The present work is devoted to an investigation on the soil to mushroom transfer parameters for 137Cs and 40K radionuclides, as well as for some stable elements and heavy metals. The results of transfer factors for 137Cs and 40K were within the range of 0.06–3.15 and 0.67–5.68, respectively and the most efficiently transferred radionuclide was 40K. The TF values for 137Cs typically conformed to a lognormal distribution, while for 40K showed normal distribution. Statistically significant correlations between 137Cs soil to mushroom transfer factors and agrochemical soil properties have been revealed. Although the concentration ratios varied within the species, the most efficiently transferred elements seems to have been K, followed by Rb, Zn, Cu, Cd, S, Cs and Hg.

Title: 137Cs, 40K, alkali–alkaline earth element and heavy metal concentrations in wild mushrooms from Turkey
Author: Özlem Karadeniz, Günseli Yaprak
Reference: Journal of Radioanalytical and Nuclear Chemistry , September 2010, Volume 285, Issue 3, pp 611-619
DOI: 10.1007/s10967-010-0575-8
Keywords: Mushroom, 137Cs, 40K, Internal dose, Alkali–alkaline earth elements, Heavy metals
Abstract: In 2002, an extensive study was performed in forest sites of Izmir. This first study results led on the one hand, to quantify of 137Cs and 40K concentration in mushrooms collected in the Izmir region and to a first evaluation of dose in people due to the ingestion of radionuclide-contaminated mushrooms. The mushroom concentration values varied over a wide range from below detection limit to 401 ± 4 Bq kg−1 (dry wt) for 137Cs. The 40K concentration values obtained for different species of mushrooms ranged from 588 ± 26 Bq kg−1 to 2024 ± 63 Bq kg−1 (dry wt). The annual effective dose values due to mushroom ingestion for 137Cs are lower than the ICRP-2007’s reference level value of 1 mSv for “existing” exposure situation. Inductively coupled plasma-mass spectrometry was used to measure many alkali–alkaline earth elements and heavy metals in mushroom samples. The relationships among the concentrations of 137Cs and the stable elements were presented and the occurrence of metals in mushrooms was evaluated.

Title: Radioactive pollution of Turkish biotas one year after the Chernobyl accident

DOI: 10.1007/BF02166951
Keywords: Radioactive pollution, Turkey, biota
Abstract: Long-lived fission radionuclides spread out after the Chernobyl accident have been measured in samples collected from the Black Sea and at the Aegean coasts of Turkey between June 15 and September 15, 1987. Nondestructive analysis was performed using high resolution γ-spectroscopy. The activity remaining 16 months after the event was found to be enhanced in coniferous needles as well as in lichens, while foodstuff did not show any appreciable contamination. The relatively high106Ru/134Cs and144Ce/134Cs ratios compared to those found in analogous samples from Southern Europe, might result from a fractionation between refractory and volatile elements.
