AN ABSTRACT OF THE THESIS OF Margaret C. Myers for the degree of Master of Science in Radiation Health Physics presented upon July 13, 2012 Title: Use of GIS Software to Map Contaminant Distributions and Determine Integrated Dose for Purposes of Assessing Impact to Biota Abstract approved:

Kathryn A. Higley The objective of this research was to estimate the radiological impact on various nonhuman 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 of Education, Culture, Sports, Science and Technology in Japan (MEXT) were used to approximate doses to various organisms. Cumulative doses and dose rates were plotted in ArcGIS 10, geographic information system (GIS) software, and Kriging interpolations were performed between the sampling points. The conclusion of this preliminary investigation that there appears to be the potential for adverse biological impacts of the studied biota; however, the magnitude of the impact will require further investigation.
