Title: Radionuclide uptake by trees at a radwaste pond in Washington State

Abstract

This paper presents work conducted in the summer of 1980 by Rockwell Hanford Operations, Hanford, WA, in support of a proposed effort to decommission and decontaminate a Hanford radwaste pond (216-U-10 Pond). The radionuclide values presented here are in addition to the U-Pond work that was recently published (La83) and are below any levels of environmental concern and within state and federal guidelines. U-Pond was constructed in 1944 for the surface disposal of industrial waste waters from nuclear separation processes and is one of the longest used aquatic, low-level, radioactive waste-disposal sites in the world. Tree leaf/twig, root, core and soil samples were collected and analyzed for /sup 137/Cs, /sup 90/Sr and /sup 239/Pu//sup 240/Pu. Strontium-90 was more readily taken up by trees than /sup 137/Cs or /sup 239/Pu//sup 240/Pu. Soil concentration values for /sup 137/Cs and /sup 239/Pu//sup 240/Pu were significantly greater (p less than or equal to 0.05) than all tree component parts. Radionuclide concentration ratios were higher for /sup 90/Sr (0.01-1355.0) than for /sup 137/Cs and /sup 239/Pu//sup 240/Pu for all tree components examined. Concentration ratios for /sup 239/Pu//sup 240/Pu ranged from 10(-6) to 10(-2) and are comparable to other studies conducted at the US Department ofmore » Energy's Oak Ridge and Savannah River Laboratories. These data represent the first quantitative information with respect to radionuclide uptake by trees on the Hanford Site.« less
