Abstract

From 1988 through 2004, samples of upper-layer sediments from the Columbia River and Snake River were collected under the Hanford Site Surface Environmental Surveillance Project to document concentrations and trends of radionuclides. Low concentrations of potassium-40, cesium-137, uranium isotopes, and plutonium isotopes were detected consistently in sediment samples over the entire sampling period. The concentrations of most radionuclides were similar to values measured upstream of the Hanford Site behind Priest Rapids Dam. For all locations, the concentrations of radionuclides in sediment samples from the Columbia and Snake rivers were below concentrations that would result in a 1-mrem effective dose equivalent to a hypothetical exposed individual using a shoreline exposure scenario (i.e., 500 hr/yr of external dose). The DOE limit for public exposure is 100 mrem/yr.

Radiological survey of exposed shorelines and islands of the Columbia River between Vernita and the Snake River confluence

Technical Report Sula, M

This document describes a radiological survey which was performed to evaluate the magnitude and distribution of radioactive contamination on the exposed shorelines of the Columbia River along and downstream of the Hanford Site. The area encompassed by the survey includes the low-lying exposed land on both sides of the river from the uppermost point of production reactor discharge into the river at 100-B Area to the confluence of the Snake and Columbia Rivers, almost 60 miles downstream of the starting point. External exposure rate measurements were made at nearly 30,000 locations during the survey - accounting for approximately 60% ofmore »« less

Hydrodynamic Simulation of the Columbia River, Hanford Reach, 1940--2004

Technical Report Waichler, Scott; Perkins, William; Richmond, Marshall

Many hydrological and biological problems in the Columbia River corridor through the Hanford Site require estimates of river stage (water surface elevation) or river flow and velocity. Systematic collection of river stage data at locations in the Hanford Reach began in 1991, but many environmental projects need river stage information at unmeasured locations or over longer time periods. The Modular Aquatic Simulation System 1D (MASS1), a one-dimensional, unsteady hydrodynamic and water quality model, was used to simulate the Columbia River from Priest Rapids Dam to McNary Dam from 1940 to 2004, providing estimates of water surface elevation, volumetric flow rate,more »« less

Cycling of transuranic radionuclides in the Columbia River, its estuary, and the North Pacific Ocean. Progress report, February 1, 1978--February 15, 1979

Technical Report Beasley, T; Holton, R

Progress from February 1978 through January 1979 on the measurement of radionuclides in the Columbia River and its estuary, with principal emphasis on plutonium isotopes is reported. The goal is to budget the inventory of transuranic radionuclides in the Columbia River system below the Hanford Complex and to estimate the amounts of Pu and Am being carried to the Northeast Pacific Ocean by the river. The results to date have led to conclusions of some importance to the Department of Energy. These are as follows: (1) previously published data on the concentrations of plutonium in McNary reservoir are incorrect. Themore »« less
Survey of Potential Hanford Site Contaminants in the Upper Sediment for the Reservoirs at McNary, John Day, The Dalles, and Bonneville Dams, 2003

Technical Report Patton, Gregory; Priddy, M; Yokel, Jerel; ...

This report presents the results from a multi-agency cooperative environmental surveillance study. of the study looked at sediment from the pools upstream from dams on the Columbia River that are downstream from Hanford Site operations. The radiological and chemical conditions existing in the upper-level sediment found in the pools upstream from McNary Dam, John Day Dam, The Dalles Lock and Dam, and Bonneville Dam were evaluated. This study also evaluated beach sediment where available. Water samples were collected at McNary Dam to further evaluate potential Hanford contaminants in the lower Columbia River. Samples were analyzed for radionuclides, chemicals, and physicalmore »« less

Estimates of Columbia River radionuclide concentrations: Data for Phase 1 dose calculations

Technical Report Richmond, M; Walters, W

Pacific Northwest Laboratory is conducting the Hanford Environmental Dose Reconstruction Project to estimate the radiation doses people may have received from historical Hanford Site operations. Under the direction of an independent Technical Steering Panel, the project is being conducted in phases. The objective of the first phase is to assess the feasibility of the project-wide technical approach for acquiring data and developing models needed to calculate potential radiation doses. This report summarizes data that were generated for the Phase 1 dose calculations. These included monthly average concentrations of specific radionuclides in Columbia River water and sediments between Priest Rapids Dammore »« less
