Tóm tắt :

20 p. Radioactive materials are introduced into the environment from a number of sources – naturally-occurring and man-made. The naturally-occurring sources include those substances produced by cosmic rays, which may find their way to water courses with rainfall and run-off, and those present in the soil, such as uranium-238 and its daughters radium-226 and, radon-222. The man-made radionuclides are those resulting from fallout from nuclear tests, nuclear power production, and medical and other beneficial uses of radioactive materials. Increases in environmental releases resulting from beneficial practices could add to the amount of radioactive substances in surface and ground water and could have a direct effect on radioactivity levels in water sources used for public water supply. These increased discharges thus suggested the need to review the current radioactivity levels included in the WHO drinking-water standards. Accordingly, the WHO Regional Office for Europe, in cooperation with the Government of Belgium, convened a Working Group on Examination of Drinking-water for Radioactive Substances in Brussels on 7–10 November 1978. The Working Group was to review the current WHO drinking-water standards pertaining to radioactivity in drinking-water and recommend revisions as appropriate. The Group also discussed procedures for sampling and analysis of radon-222 to be incorporated in the manual on Analysis for Water Pollution Control.
