Fukushima's legacy
Date:8/14/2014

Following the 1986 Chernobyl nuclear power plant meltdown, biological samples were obtained only after extensive delays, limiting the information that could be gained about the impacts of that historic disaster. Determined not to repeat the shortcomings of the Chernobyl studies, scientists began gathering biological information only a few months after the disastrous meltdown of the Fukushima Daiichi power plant in Japan in 2011. Results of these studies are now beginning to reveal serious biological effects of the Fukushima radiation on non-human organisms ranging from plants to butterflies to birds.

A series of articles summarizing these studies has now been published in the Journal of Heredity. These describe widespread impacts, ranging from population declines to genetic damage to responses by the repair mechanisms that help organisms cope with radiation exposure.

"A growing body of empirical results from studies of birds, monkeys, butterflies, and other insects suggests that some species have been significantly impacted by the radioactive releases related to the Fukushima disaster," stated Dr. Timothy Mousseau of the University of South Carolina, lead author of one of the studies.

Most importantly, these studies supply a baseline for future research on the effects of ionizing radiation exposure to the environment.

Common to all of the published studies is the hypothesis that chronic (low-dose) exposure to ionizing radiation results in genetic damage and increased mutation rates in reproductive and non-reproductive cells.

One of the studies (Hayashi et al. 2014) documented the effects of radiation on rice by exposing healthy seedlings to low-level gamma radiation at a contaminated site in Fukushima Prefecture. After three days, a number of effects were observed, including activation of genes involved in self-defense, ranging from DNA replication and repair to stress responses to cell death.
