Monitoring the genotoxicity of radiocontaminants in Swedish lakes by fish micronuclei.
The frequency of micronuclei in erythrocyte cells from fish collected in six Swedish lakes with high concentrations of radiocaesium and other suspected natural and induced pollutants, was investigated. The frequency was enhanced in some lakes but was not correlated with caesium concentrations. Fish could prove to be interesting models for investigations of ionizing radiation effects at low doses because of their sensitivity.
