A study on distribution of natural radionuclide polonium-210 in a pond ecosystem

摘要

This paper presents the results of an investigation on the distribution of ~210Po in Mutharasanallur pond ecosystem. It has been demonstrated that ~210Po is non-uniformly distri- buted within the ecosystem. The results of the study show a dissolved ~210Po concentration in pond water of 1·4mBq·l~-1. The sediment sample recorded a ~210Po activity of 59·9Bq·kg ~-1. The aquatic organisms showed differential accumulation of the radionuclide with enhanced bioac- cumulation in soft tissues and muscle. The ~210Po activity in the biota fell within the range of 1·2-53·3 Bq·kg~-1 (wet wt.).
