Differences in effects of radiation on abundance of animals in Fukushima and Chernobyl-PDF

Radioactive contamination can negatively affect the abundance of living beings through the radiation and chemical toxic effects of radionuclides or the effects of mutation accumulation over time. If radiotoxic effects were the main determinant of the abundance of organisms, we should expect a reduction in abundance immediately following radioactive contamination, while we should expect a gradual increase in negative effects over time if mutation accumulation was the main determinant.
