Fukushima's Biological Legacy

An anonymous reader sends this report from Eurekalert: Scientists began gathering biological information only a few months after the disastrous 2011 meltdown of the Fukushima power plant in Japan. 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 been published in the Journal of Heredity describing impacts ranging from population declines to genetic damage (abstract 1, abstract 2, abstract 3, abstract 4). 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. Meanwhile, efforts to restart Japan's nuclear power program are dead in the water.

How accurate is the Eurekalert article?

Did the AC submitter read the abstracts? Did they understand them?
* The papers on chronic (low-dose rate) exposures focussed on the DNA repair and other healthy mechanisms in the exposed organisms.
* Some of the butterfly exposures were done as high-dose rate simulations in the lab, not env exposures.
* The monkey blood-count study was mentioned in the Eurekalert article, but NOT in any of the *journal* (of heredity) papers that I could see; it has been widely criticized on several bases (improbably-low causative dose and insufficient statistical power).
* Look at the refutations at the bottom of this sensational Guardian article:

“Unfortunately yet another paper with insufficient power to distinguish real effects and relevance to human health”
"correlations between the caesium and low blood counts in the Fukushima study were not statistically strong."
"monkeys are about the same as those found in sheep in some parts of the **UK** following the Chernobyl accident, i.e. extremely low .."
"in terms of damage to the animals themselves. I think it much more likely that the apparently low blood cell counts are caused by something other than radiation"
