摘要

Few data are available to quantify the transfer of both natural and anthropogenic ra-dionuclides to detritivorous invertebrates to facilitate estimation of the internal dose to such biota in models used to assess radiation exposure. To enhance the available data, activity concentrations Of ~(137)CS, ~(40)K, ~(90)Sr, ~(239+240)pu, 241 Am, ~(235) U and ~(238)U were measured in ants (Formicidae) and corresponding undisturbed soil collected from the Zlatibor mountain in Serbia and ant/soil concentration ratios (CR) calculated. The ~(241)Am concentration ratios for ants were fourfold higher than those calculated for ants in a previous study whereas they are similar to the more numerous data previously reported for a range of detritivorous invertebrates in other studies. CR values for ~(137)Cs in ants were similar to the few other reported values and slightly lower than those for a range of detritivorous invertebrates. Those for ~(239+240)pu were slightly higher than those for ants in two other studies but they were close to upperrnlimit of a range of data reported for detritivorous invertebrates. All the CR values will be included in a future revision of the ERICA Tool database and will particularly improve the information available for uranium.
