Abstract |
The Radiation Advisory Committee of the Science Advisory Board has completed its review of the Office of Drinking Water's evaluation of radionuclides in drinking water and four draft criteria documents that support the evaluation, including Man-Made Radionuclide Occurrence, Radium, Radon and Uranium. The Committee addressed four issues: the weighting factors to be used in effective dose equivalent calculations, the chemical toxicity and radiotoxicity of uranium, the linearity of the dose-response curve for naturally occurring radionuclides, and the appropriate use of the relative and absolute risk models. The Subcommittee concludes that the Office of Drinking Water has developed scientifically comprehensive assessment documents. |
