Women were experiencing miscarriages, stillbirths, and genetic abnormalities in their children. Researchers learned that the coral soil behaved differently from mainland soil because it contains very little potassium. Plants and trees readily absorb potassium as part of the normal biological process, but since caesium is part of the same group on the periodic table, it is absorbed by plants in a very similar chemical process. The islanders who unknowingly consumed contaminated coconut milk were found to have abnormally high concentrations of caesium in their bodies. The Trust Territory decided that the islanders had to be evacuated from the atoll a second time.
