Water quality considerations - Project Travois

Description: The technical concept for Project Travois contains one simple analysis of the potential hazard of contaminating the Arrowrock Reservoir on the Boise River with some of the radionuclides produced. This previous analysis assumes homogeneous and prompt mixing of all the tritium and tungsten isotopes. This simple analysis is physically unrealistic sine there is no way of transporting all of these radionuclides to the reservoir, promptly. We shall in this paper reanalyze the contamination problem in such a way that we define the type of site geology and hydrology information that must be developed.

Evaluation of dredged material proposed for ocean disposal from Liberty Island Anchorage, New York

Description: Sediment samples were collected from the Liberty Island Anchorage and Military Ocean Terminal in Bayonne, New Jersey (MOTBY), during a survey conducted from June 7 through June 10, 1994. Tests and analyses were conducted on Liberty Island Anchorage sediment core samples according to the manual developed by the U.S. Army Corps of Engineers (USACE) and the U.S. Environmental Protection Agency (EPA), Evaluation of Dredged Material Proposed for Ocean Disposal (Testing Manual), and the regional manual developed by the USACE-New York District (NYD) and EPA Region 11, Guidance for Performing Tests on Dredged Material to be Disposed of in Ocean Waters. The evaluation of proposed dredged material from Liberty Island Anchorage consisted of bulk sediment chemical analyses, chemical analyses of site water and elutriate, and water-column and benthic acute toxicity tests. Individual sediment core samples collected from Liberty Island Anchorage were analyzed for grain size, moisture content, and total organic carbon (TOC). A composite sediment sample, representing the entire area proposed for dredging, was analyzed for bulk density, metals, chlorinated pesticides, polychlorinated-biphenyl (PCB) congeners, polynuclear aromatic hydrocarbons (PAH), 1,4-dichlorobenzene, and dioxin/furan congeners. Site water and elutriate water, prepared from the suspended- particulate phase (SPP) of Liberty Island Anchorage sediment, were analyzed for metals, pesticides, and PCBS.

Research and development program, fiscal year 1970

Description: The biomedical program of the Laboratory of Nuclear Medicine and Radiation Biology for FY 1970 is conducted within the scope of the following categories: Somatic Effects of Radiation; Combating Detrimental Effects of Radiation; Molecular and Cellular Level Studies; Environmental Radiation Studies; Radiological and Health Physics and Instrumentation; Cancer Research; and Selected Beneficial Applications. The overall objectives of the Laboratory within these areas of the Biology and Medicine Program may be summarized as follows: (1) investigation of the effects of ionizing radiation on systems of biological significance and on living organisms; (2) assessment and study of the immediate and long term consequences of the environmental radioactivity on flora, fauna, and man; (3) development of beneficial uses of ionizing radiation and radioactive substances in medicine and biology; and (4) the conduct of training and educational activities in fields related to the biological and medical aspects of radiation.

Hazard analysis for cesium shipments

Description: The rail shipment of large quantities of radiocesium involves a potential accidental release of this material in a readily available form to the biosphere. The magnitude of the associated potential damage to man and his environment is evaluated in this report. The evaluation of the consequences of an accidental release of Cs-137 from the Shielded Transfer Tank, Model II (STT) assumes loss of Cs-137 to the atmosphere or to surface-water. Release to the atmosphere could result from a collision followed by fire or explosion. In the event of a fire, a small fraction of the Cs-137 vould be volatilized. An explosion would disperse the Cs-137 still adsorbed to Decalso as particulates. In either case, the material is assumed to be dispersed by atmospheric mechanisms which can be described by modified Sutton equations. The accident involving a fire or explosion assumes that 1 percent or 10 percent, respectively, of 90,000 curies of Cs-137 is dispersed in a metropolitan area. Contamination of the surrounding suburban area is also involved. Damage estimates amount to about 60 million dollars and 400 million dollars, corresponding to a 1 percent and a 10 percent release respectively. Another possible type of accident involves the release of the Decalso (an inorganic ion exchange carrier for the cesium) into a river. However, the release of Cs-137 by elution into the river results in minor damage compared to the atmospheric release cases.
