Reactor cooling water samples fr9m the Hanford Operation at Richland, Washington, have undergone particulate separations and study utilizing recently developed ultracentrifugation techniques. The suspended parti cles contained in these samples were separated into classifi~d groups and then subjeded to a variety of analytical investigations including ele mental and radiochemical analyses. The samples selected for study were taken in sets ranging from o~e to four samples per set. Six sets or a total of sixteen samples were collected and shipped to the Biophysical Limnology Laboratory at Oak Ridge for study. The analytical results from these investigations are summarized in a series of tables. selected for the more prominent radio nuclides the particulate or the dis solved fractions contained in the sample volume. A few of the radionuclide parent elements such as chromium, sulphur, and zinc were found almost entirely associated with the dissolved materials fraction. These results along with the other data showed that the sus pended materials isolated from the various samples of reactor cooling water did not add significantly to the production of radionuclides and the radioactive pollution of the Columbia River at Hanford.
