aggregation coefficients - Opis:
- The paper presents results for the 137Cs, 90Sr, 40K activity concentrations and 228Th/232Th, 230Th/232Th activity ratios in several samples needles from two Norway spruce (Picea abies) trees and two soil samples collected in the Tatra Mountains (Poland) area. Activities for artificial 137Cs and 90Sr show moderate values. Statistically different values were found between the mean concentration of 90Sr and 137Cs in current (C) and two years old (C+2) needles of the first tree, whereas for potassium no significant difference was observed. For the second, fallen tree, no significant difference between the mean activity concentration in needles for C+1 and C+2 was found for each radionuclide, but much lower levels of 137Cs contamination were observed. Observed values of the aggregation coefficients for 137Cs and 90Sr are presented.
