Series Description: This 1960 report provides information on the deposition of low-level radioactive waste discharged into the Clinch and Tennessee rivers by ORNL. The purpose of the report, which is based on data collected from surveys of these rivers since 1951, is to assess the reconcentration and absorption of radioactive material in riverbed sediments. It evaluates the hazards to humans from the radioactivity in the sediments, estimates the ability of the Tennessee River system to continue receiving and storing radioactive contaminants, determines the effects of an increase in bottom radioactivity on industry, and makes recommendations on further waste disposal in the system. Instrumentation, calibration, and procedures are discussed. Figures and tables include information on the presence of cesium 137, strontium-90, cerium-144, ruthenium-106, cobalt-60, and rare earth elements in the river sediments with beta and gamma counts and radioactivity levels in relation to the riverbed contour.
