Determination of beta activity in water
F. B. Barker, B.P. Robinson
1963, Water Supply Paper 1696-A
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...
