Molluscs as indicators of environmental pollution by radionuclides
- Shmal`gauzen Inst. of Zoology (Ukraine); and others
Theoretical and systematical aspects of the utilization of molluscs were elaborated in an effort to bioindicate pollution by radionuclides after the accident at Chernobyl` Atomic Electric Power Station (CAEPS). Beta-radiometry of shells, gamma-spectroscopy of shells and animals, and a number of chemical and radiochemical analyses were carried out. The composition of radionuclides, incorporated by molluscs before and after the accident, is cited. Average values of the factors of transition and accumulation (relative to water) {sup 90}Sr and {sup 137}Cs are estimated. Individual variability and taxonomic distinction of these parameters for {sup 90}Sr are analyzed. The results of radioecological monitoring of rivers of the Dnieper basin and reservoirs of the Dnieper cascade are shown. Direct beta-radiometry of molluscan shells is recommended as the most convenient method of rapidly estimating the level of pollution of the area of {sup 90}Sr.
