Many elements have one or more naturally radioactive isotopes, and several hundred other radionuclides have been produced artificially. Radioactive substances may be present in natural water as a result of geochemical processes or the release of radioactive waste and other nuclear debris to the environment. The Geological Survey has developed...
Chemical quality of surface waters in Pennsylvania
Charles N. Durfor, Peter W. Anderson
1963, Water Supply Paper 1619-W
