Little evidence for health effects of contaminated fish following Fukushima accident

Recent reports in the popular press cite evidence for contamination of tuna and other fish by unnatural radionuclides released after the Fukushima nuclear disaster.  These reports occasionally assert possible consequences to human health, usually without context or reference to rigorous, evidence-backed models. Some reports state that the mere presence of these elements is dangerous without […]
