Radiologic sampling of surface soils near a USEPA superfund site

Creator:: Blakeman, Christopher John
Abstract:: The human health effects of acute exposure to high levels of ionizing radiation are well understood; however, when these irradiations occur at low levels, there is controversy as to their potential health threat (BEIR V, 1990). For individuals living in areas where the level of naturally occurring background radiation is...

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®...

Determining the bioavailability of soil-associated radium using in vitro methodology

Creator:: Tack, Krystina M.
Abstract:: Soil that is contaminated with radioactive elements poses an exposure hazard to those whom may take up temporary or permanent residence on such a site. Of particular interest is the internal exposure from ingestion of this radioactive soil. Although most ingestion of soil is inadvertent, usually being attached to foodstuffs...

Biological remediation strategy for immobilizing Ag-110m and Cs-134 in soils

Creator:: Whitlow, Jesse Lynn
Abstract:: After contamination of soil in Japan due to the Fukushima Daiichi accident, there has been an increased interest in remediation of radiologically contaminated land. This study investigated the efficacy of a new biological remediation technology developed by Earthfort, an Oregon based company to hold radionuclides at the soil surface. Cesium-134...

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...

Use of GIS software to map contaminant distributions and determine integrated dose for purposes of assessing impact to biota

Creator:: Myers, Margaret C.
Abstract:: The objective of this research was to estimate the radiological impact on various non-human biotas by the Fukushima Daiichi Nuclear power plant radiation release resulting from Japan's tsunami in March 2011 consistent with the recent recommendations of the International Commission on Radiological Protection. Soil concentration data given by Japan's Ministry...

A comparison of deterministic and probabilistic radiation dose assessments at three fictitious ¹³⁷Cs contaminated sites in California, Colorado, and Florida

Creator:: Brock, Terry A.
Abstract:: Two methods of radiation dose assessment were evaluated for the Cs-137 in soil ⇒ leafy vegetable ⇒ human consumption exposure pathway at three fictitious contaminated sites in California, Colorado, and Florida. An annual dose equation was developed and per USEPA risk assessment guidelines, traditional, single point annual dose estimates were...

A study of residual Cesium 137 contamination in southwestern Utah soil following the nuclear weapons tests at the Nevada Test Site in the 1950's and 1960's

Creator:: Bentley, R. Blair
Abstract:: The Nevada Test Site (NTS) was the location for at least 100 above ground Nuclear Weapons tests during the 1950's and early 1960's. Radioactive fallout from these tests spread to many areas north and west of the NTS. According to estimates from the NCI and DOE, Washington County, Utah was...

Establishment of concentration ratios for riparian and shrub steppe areas of the eastern Washington Columbia basin

Creator:: Napier, Jonathan Bamberger
Abstract:: Concentration ratios are used to determine the transfer of nuclides from soil to biota to fauna. Some nuclides have limited associated data though, this has not prevented predictions from being performed at sites without associated data. These ratios are site specific and are not fully applicable when applied to other...
