Chromium-51 as a Radioactive Tracer of Columbia River Water at Sea
Science (New York, N.Y.)
|December 17, 1965
Abstract:
The plume of the Columbia River was followed 350 kilometers to sea by measurement of its chromium-51 content. This radioactive tag, introduced into the river by nuclear reactors at Hanford, Washington, promises to provide a useful oceanographic tool for determining rates of transport and mixing, and for identifying plume waters in the presence of other sources of fresh water.
