There was a recent report in Nature about two groups of monkeys. One group was in Fukushima, and the other group was about 70 km away. The report stated:
Compared with Shimokita monkeys, Fukushima monkeys had significantly low white and red blood cell counts, hemoglobin, and hematocrit, and the white blood cell count in immature monkeys showed a significant negative correlation with muscle cesium concentration. These results suggest that the exposure to some form of radioactive material contributed to hematological changes in Fukushima monkeys.
This study in a reliable journalSupports the notion that significant Injury to the bone marrow of monkeys has been caused by the radiation disaster at Fukushima.
