Dating of fallout in lacustrine sediment in southwestern Utah
… of southwestern Utah which received the highest fallout from Nevada Test Site (NTS) nuclear testing during the period 1951-1959. The reservoir was shown to have a constant sedimentation rate and to be relatively undisturbed. A 40 centimeter (cm) core taken from this reservoir contained sediment …

Online Communities and Offline Criminal Justice: The Digital Fallout of Major Criminal Incidents
<p>User-generated online data has, in recent years, become an important basis for sociological research, and the ubiquity of social media presages the importance of an increased understanding of its inner workings in the spheres of criminology and sociology. This dissertation examines the dynamics …

Nuisance to nemesis: nuclear fallout and intelligence as secrets, problems, and limitations on the arms race, 1940-1964
Fallout sampling and other nuclear intelligence techniques were the most important sources of United States strategic intelligence in the early Cold War. Operated as the Atomic Energy Detection System by a covert Air Force unit known as AFOAT-1, the AEDS detected emissions and analyzed fallout from …

Impact on soil chemistry of atmospheric sulfur fallout near Arnot coal-fired power station, in the Eastern Transvaal highveld region, South Africa
The objective of the study was to evaluate the potential impact of atmospheric sulfur deposition on the soils surrounding Arnot power station. In particular, the study focused on the relationship between sulfur and organic carbon (OC) and on the various pools of sulfur in the soil. A representative …

Investigating the Use of Fallout Radionuclides Beryllium-7 and Excess Lead-210 as Short-Term Stream Sediment Chronometers in the Agricultural Upper Midwest, USA
… In the first chapter of my thesis, I use the fallout radionuclides beryllium-7 and excess lead-210 to estimate the relative time since precipitation exposure, or “age”, of suspended sediment at various points in a stream system in eastern Wisconsin during storms. The purpose of this work was …
