“…Reasons for nonradioactive T. aestivum possibly involve species-specific requirements for soil structure and chemistry, together with mycelium depth, melanin content, and/or the lack of 137 Csbinding pigments. It has also been argued that calcium carbonate reduces the soil-plant/fungi transfer of 137 Cs, while its availability for organisms is elevated in nutrient-poor organic soil horizons (Mascanzoni, 2001(Mascanzoni, , 2009. Truffles generally fruit near the surface of calcareous substrate (Stobbe et al, , 2013.…”

Abstract. Although ranging among the most expensive gourmet foods, it remains unclear whether Burgundy truffles (Tuber aestivum) accumulate radioactivity at a harmful level comparable to other fungal species. Here, we measure the 137 Cs in 82 T. aestivum fruit bodies from Switzerland, Germany, France, Italy, and Hungary. All tested specimens reveal insignificant radiocaesium concentrations, thus providing an all-clear for many truffle hunters and cultivators in large parts of Europe as well as the subsequent chain of dealers and customers from around the world. Our results are particularly relevant in the light of ongoing efforts to cultivate Burgundy truffles, as well as the fact that several forest ecosystems are still highly contaminated with 137 Cs, for which mushrooms are one of the main pathways to human diets.

“…A study published in 1992 presented data on 383 samples (22 species) of edible mushrooms collected between June and September in 1986 and analysed for radiocaesium (Mascanzoni, 1992). There was a large variation in activity concentrations between samples; Agaricus arvensis on average contained 360 Bq/kg dw, whereas Rozites caperata contained 1,154,110 Bq/kg dw.…”

Suillus variegates showed constant levels during the period, around 100 000 Bq/kg dw, whereas the activity concentration increased moderately in Cantharellus spp.…”

Comparative analysis of¹³⁷Cs bioavailability in forest ecosystems of different type

Abstract.A quantitative analysis of ,37 Cs bioavailability in forest soils in the long term after the Chernobyl NPP accident based on a 3 years (1996-1998) investigation is presented. Five sites with different trees composition and properties of soil were studied to identify factors determining radiocaesium transfer to trees and different under story species. The following parameters were investigated: ,,7 Cs activity concentrations and its speciation in various horizons of forest soil, accumulation of this radionuclide by different species of under story vegetation and distribution of their root biomass in the soil profile. It has been shown that one decade after the deposition maximum l37 Cs activity in soil of the experimental sites considered is located in different soil layers dependent on moisture regime, characteristics of litter and soil properties. High level of heterogeneity of 137 Cs specific activity in different parts of tree, which is related to physiological peculiarities of their functions, has been shown. The data obtained have demonstrated a non-uniform character for i37 Cs distribution along trunks, which can be explained by radionuclide fixation by walls of xylem vessels and by changes in geometry along the tree trunk. It has been found that the radial distribution of l37 Cs in the tree trunk is dependent on the availability of 137 Cs in soil, which governs the transfer of this radionuclide via xylem sap, and on the properties of the xylem. The accumulation of m Cs by both trees and under story species was influenced by J7 Cs vertical distribution and availability in soil as well as by the root (mycelia) biomass distribution in different soil horizons. A "bioavailability factor", which takes into account the above factors, is proposed for comparative analyses of l37 Cs transfer from soil to plants in different types of forest ecosystems.
