Investigation of depleted uranium migration offsite from a military ordnance range : potential concentrations and radiological doses

Creator:: Rynders, David G.
Resource Type:: Masters Thesis

Determining preliminary remediation goals for contaminated Hanford sites

Creator:: Hekkala, Darin R.
Abstract:: The Hanford nuclear reservation in Washington state was initially created during World War II for the production of plutonium to be used in atomic bombs. A perceived need for a large increase in the number of nuclear weapons spurred expansions in production facilities at Hanford through the 1960's, and production...

Development of a functional prototype of an environmental risk assessment parameter database on the World-Wide Web

Creator:: Potter, Nathan Kent
Abstract:: The goal of the project was to develop a functional prototype of an environmental risk assessment parameter database on the World-Wide Web. The ability to develop a consolidated environmental database has become possible due to the phenomenal growth of the Internet and the World-Wide Web over the past few years....

Calculation of scanning efficiencies for portable instruments used to detect particulate contamination

Creator:: Moss, Stephen Craig
Abstract:: Efforts are continually being made in remediation surveys to reduce the time and manpower required to perform work while maintaining the ability to detect low levels of contamination. To this end, organizations are utilizing portable instrumentation in conjunction with global positioning systems (GPS). This combination of technologies allows a surveyor...

Application of autoradiographic techniques for contaminant distribution studies in soils

Creator:: Povetko, Oleg G.
Abstract:: In order to determine the physical location of contaminants in soil, two solidified soil "thin" sections, which preserve the undisturbed structural characteristics of the original soil, containing weapons-grade plutonium from the Rocky Flats Environmental Test Site were prepared. Two autoradiographic methods were used in radionuclide mapping: contact autoradiography using CR-39®...

Environmental pathway analysis of a radioactive zirconium sand uploading facility

Creator:: Miller, Robert E.
Abstract:: The Teledyne Wah Chang facility is a manufacturer of the rare metal zirconium. The facility has been in constant production since 1956. In 1973 an attempt to utilize different sand ore sources from Nigeria and India in a new carbiding process, prior to chlorination, failed. The resulting byproducts of the...

Predicting instrument detection efficiency when scanning small area radiation sources

Creator:: Hart, Kevin G.
Abstract:: Accurate quantification of radionuclides detected during a scanning survey relies on an appropriately determined scan efficiency calibration factor (SECF). Traditionally, instrument efficiency was determined from a fixed instrument to source geometry. However, as is often the case, the instrument is used in a scanning mode where the source to instrument...

A method for predicting peak scanning detection efficiency of a cylindrical sodium iodide scintillation detector

Creator:: Duffy, William L.
Abstract:: Scanning surveys of building surfaces and land areas are performed with radiation detection equipment to identify areas of elevated radioactivity. To quantify the extent and magnitude of the contamination, follow-up radiation surveys and soil sampling are usually required. The ability to accurately quantify discrete locations or "hot particles" of contamination...
