Hayama says that "This first data from non-human primates -- the closest taxonomic relatives of humans -- should make a notable contribution to future research on the health effects of radiation exposure in humans."
Despite the fact that this data seems fairly indicative of the effects of radioactivity on these local primates, some scientists disagree. "Unfortunately this is yet another paper with insufficient power to distinguish real effects and relevance to human health," says Professor Geraldine Thomas, at Imperial College London. Professor Jim Smith, from the University of Portsmouth elaborates this skeptical sentiment by saying that "The levels of radiocaesium in the Fukushima 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."
