Radium-226 in drinking water and terrestrial food chains: transfer parameters and normal exposure and dose
Environmental transport of Ra-226 from geological formations to drinking water and from soil to vegetation, meat, and milk was quantitatively analyzed following a literature review. Both natural and industrial sources were investigated. Particular attention was given to references specific for the phosphate-mining region of southwestern Florida. Literature sources have been interpreted to develop concentration factors describing terrestrial food-chain transport. Unweighted means and associated ranges of concentration-factor values, representing averages of data collected over a variety of environmental conditions, soil types, and chemical forms, are provided. Annual human exposure and 50-yr dose commitments to bone, lung, liver, kidney, and whole body were estimated by assuming mean concentration factors as well as average annual food and water consumption rates.
