When I read the story, I do what I always do, and shot off a note to Ralph Andersen, NEI's chief health physicist. Here's what he had to say about the study:
Please note that there are species of plants, insects and animals that are particularly sensitive to changes in environmental conditions, including radiation. The pale grass butterfly is among the most sensitive, which is why it was selected for study following the accident at Fukushima Daiichi.Good advice, and just the sort of guidance we ought to be paying attention to when we read headlines in the media. In the meantime, some nuclear bloggers have taken a closer look and have shared some similar thoughts. Please visit Atomic Insights and Nuclear Diner for more. Also, be sure to check in with the conversation on Reddit.
This article provides a rational perspective on what has been found, what it may mean, and what it doesn’t necessarily mean.
Similar findings in some species of biota were detected around Chernobyl in the first few years after the accident there, but impacts on the overall environment and ecology were relatively small and the area today is considered by scientists to be verdant and robust in regard to plant and animal life.
Fukushima Daiichi represents a major accident with significant radiological releases and there are and will be discernible consequences for some years to come. Our emphasis here is on taking actions to prevent such an event in the US and globally.
In regard to understanding the consequences there, we remain open-minded and objective, gaining (and sharing) a fact-based perspective on what it is and what it isn’t.
