Radium-226 in drinking water and terrestrial food chains: a review of parameters and an estimate of potential exposure and dose
Environmental transport of /sup 226/Ra from geological formations to drinking water and from soil to vegetation, meat and milk were quantitatively analyzed following a review of literature. 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 also provided. Annual human exposure and 50-year dose commitments to bone, lung, liver, kidney and whole body were estimated by assuming mean concentration factors as well as annual food and water consumption rates.
