Determinazione del CS-134 e CS-137 in matrici alimentari e ambientali nel territorio di serina in Lombardia.
Traduction en anglais : Determination of Cs-134 and Cs-137 in different food-stuffs and environmental-stuffs collected from Serina's area in Lumbardy.
After the explosion of the reactor n°4 in the Ukrainian Nuclear Power Plant of Chernobyl, the highest radioactive contamination in Italy was observed in Lumbardy.
In 1996, ten years after the Chernobyl's accident, the Authors carried out an investigation on soil samples from Serina area, in the district of Bergamo.
N°158 samples have been analysed by NaI (Tl) detector (3 « x3 »), collected from surface soil and subsoil, running and stagnating waters, mosses, lichens, mushrooms, water-plants, fodder leafage, berries, pine-needles, striated muscle from cattle, sheep, chamois, roe-deer, milk and cheeses from cow and goat, chicken eggs.
In all the soil samples analysed Cs-137 was detectable, and its activity was constantly higher in surface soil samples and particularly in those from woods.
In May, the seasonal fallout period at our latitudes, it has been detected on Alben Mount a light fallout of Cs-134.
In the samples collected on poly-phyto meadows no trace of Cs-137 has been detected, while in samples from wood's ecosystem this isotope was always detectable.
Cs-137 was also present in the muds of the bottom of a small natural alpine lake and in water-plants there growing.
On the basis of these data the Authors infer that mosses and lichens are the best markers of environmental contamination due to Cs-137. (...)
