Airborne and liquid releases resulted in exposure to neighbors of the plant through inhalation, uptake through crops, ingestion of milk from livestock grazing on contaminated grass, ingestion of fish or drinking water from streams and rivers contaminated with radioactive releases, and through other pathways. Inhalation was by far the most important pathway. An analysis of inhalation doses to hypothetical populations resulting from these exposures appears in the chart below. Radon from the decay of radium-226 in the K-65 silos located on the site was the cause of the largest off-site doses. Inhalation of uranium dust was the next most important.
