Task 3 Report - PCBs in the Environment Near the Oak Ridge Reservation - A Reconstruction of Historical Doses and Health Risks

Date: July 1, 1999
Creator: Price, Paul S; Widner, Thomas; Bonnevie, Nancy; Schmidt, Charlie; McCrodden-Hamblen, Jane; Vantaggio, Joanne et al.
Description: This report presents the results of an in-depth assessment of historical releases of polychlorinated biphenyls (PCBs) from the Oak Ridge Reservation (ORR) and risks of adverse health effects in local populations. The study was conducted by ChemRisk, a service of McLaren/Hart, Inc., for the Tennessee Department of Health. The project team (1) investigated releases of PCBs from the government sites, (2) evaluated PCB levels in environmental media in the area, (3) described releases of PCBs from other sources in the area, and (4) evaluated potential human exposures and health impacts associated with the historical presence of these contaminants in the environment. Beginning in the 1940s, PCBs were used extensively on the ORR and throughout the U.S. as a fire retardant in electrical components. PCBs were also used as cutting fluids for lubrication and cooling during metal working operations. Using information specific to the ORR, the project team estimated health risks for five off-site populations: (1) farm families that raised beef, dairy cattle, and vegetables on the flood plain of East Fork Poplar Creek (EFPC); (2) individuals who may have purchased beef and milk from cattle raised in the EFPC flood plain; (3) commercial and recreational fish consumers; (4) individuals that ...

Food Safety Provisions of the 2008 Farm Bill

Food Safety Provisions of the 2008 Farm Bill

Date: May 27, 2008
Creator: Becker, Geoffrey S.
Description: Food safety has re-emerged as an issue in the 110th Congress following a series of widely publicized incidents -- including adulterated Chinese seafood and pet food ingredient imports, findings of bacteria-tainted spinach, meat, and poultry produced domestically, and several large food recalls. In May 2008, Congress approved a new omnibus farm law (P.L. 110-234; H.R. 2419) that includes, among other provisions, several changes affecting U.S. food safety programs. Changes in the livestock title (Title XI) include subjecting catfish to U.S. Department of Agriculture (USDA) mandatory inspections similar to those for red meat and poultry; creating an option for state-inspected meat and poultry plants to ship their products across state lines; and requiring meat and poultry establishments to notify USDA about potentially adulterated or misbranded products.

Animal Identification and Meat Traceability

Animal Identification and Meat Traceability

Date: March 7, 2006
Creator: Becker, Geoffrey S
Description: U.S. animal agriculture is seeking to improve its ability to trace the movement of livestock from their birthplace to slaughter. The livestock and meat industries are working with the U.S. government to develop a national animal identification (ID) plan for livestock disease tracking purposes. This report focuses on animal ID and, to a lesser extent, on meat traceability.

Issues for Bringing Electron Beam Irradiators On-Line

Issues for Bringing Electron Beam Irradiators On-Line

Date: April 20, 1999
Creator: Kaye, R.J. & Turman, B.N.
Description: Irradiation of red meat and poultry has been approved by the U.S. FDA, and the U.S. Department of Agriculture's rule for processing red meat is out for comment. Looking beyond the current issues of packaging materials, labeling, and consumer acceptance, this paper reviews the next step of implementation and how to remove, or at least reduce, the barriers to utilization. Polls of the user community identified their requirements for electron beam or x-ray processing of meat or poultry and their concerns about implementation for on-line processing. These needs and issues are compared to the capabilities of the accelerator industry. The critical issues of beam utilization and dose uniformity, factors affecting floor space requirements, and treatment costs are examined.

Methodology for Estimating Ingestion Dose for Emergency Response at SRS

Methodology for Estimating Ingestion Dose for Emergency Response at SRS

Date: July 21, 2003
Creator: Simpkins, A.A.
Description: At the Savannah River Site (SRS), emergency response computer models are used to estimate dose following releases of radioactive materials to the environment. Downwind air and ground concentrations and their associated doses from inhalation and ground shine pathways are estimated. The emergency response model (PUFF-PLUME) uses real-time data to track either instantaneous (puff) or continuous (plume) releases. A site-specific ingestion dose model was developed for use with PUFF-PLUME that includes the following ingestion dose pathways pertinent to the surrounding SRS area: milk, beef, water, and fish. The model is simplistic and can be used with existing code output.

Mobile Melt-Dilute Treatment for Russian Spent Nuclear Fuel

Mobile Melt-Dilute Treatment for Russian Spent Nuclear Fuel

Date: September 17, 2002
Creator: Peacock, H.
Description: Treatment of spent Russian fuel using a Melt-Dilute (MD) process is proposed to consolidate fuel assemblies into a form that is proliferation resistant and provides critically safety under storage and disposal configurations. Russian fuel elements contain a variety of fuel meat and cladding materials. The Melt-Dilute treatment process was initially developed for aluminum-based fuels so additional development is needed for several cladding and fuel meat combinations in the Russian fuel inventory (e.g. zirconium-clad, uranium-zirconium alloy fuel). A Mobile Melt-Dilute facility (MMD) is being proposed for treatment of spent fuels at reactor site storage locations in Russia; thereby, avoiding the costs of building separate treatment facilities at each site and avoiding shipment of enriched fuel assemblies over the road. The MMD facility concept is based on laboratory tests conducted at the Savannah River Technology Center (SRTC), and modular pilot-scale facilities constructed at the Savannah River Site for treatment of US spent fuel. SRTC laboratory tests have shown the feasibility of operating a Melt-Dilute treatment process with either a closed system or a filtered off-gas system. The proposed Mobile Melt-Dilute process is presented in this paper.
