“…Neste caso, atendendo às recomendações dos códigos estratigráfi -cos, deve ser utilizada, de preferência, uma denominação geográfi ca para identifi car esses "domínios" (ver discussão e exemplos em Ulbrich et al, 2001). A equivalên-cia entre a denominação mais antiga, lançada na Figura 1 (Guimarães, 1995), e a dos "domínios petrográfi cos" (Guimarães, 2000) aparece explicada na legenda da Figura 5 (ver mais adiante).…”

Modeling Background Radiation Using Geochemical Data

Aerial gamma ray surveys have many applications in geology and science in general, such as locating mining prospects, defining radioactive plumes, and detecting nuclear weapons. Unfortunately there is currently no simple way to separate the natural gamma radiation of soil and rocks from that of contaminants such as radioactive plumes. This project used geochemical data (uranium, potassium and thorium concentrations) collected from national databases, private companies, and the NURE (National Uranium Resource Evaluation) Survey, to create forward models of exposure rates measured by aerial gamma ray surveys. We developed these techniques using an area in north central Arizona known as the Navajo Mines area, chosen for its optimal conditions for aerial gamma ray surveys and readily available survey data. Models based on geochemical I doubt I ever would have been able to finish on time without Jeremiah Smith, who endlessly helped me analyze models. I can't wait to see where you go as a scientist. Chris Adcock has been invaluable to this project by providing so many remote sensing images and endless guidance. Racheal Johnsen has been an amazing source of support throughout this experience, and I can't thank her enough for taking so much time to direct me through this process. Thank you to everyone in the Geoscience Department who made my success at UNLV possible, especially to the office staff, who were always there to answer my endless questions. I'd like to thank my parents for making all of this possible. Matt Mullen, I can't thank you enough for being my constant source of support throughout this past year. You've been amazingly kind, and I cannot wait to spend the rest of my life with you. I'd like to thank my committee: Libby Hausrath for helping me make the tough decisions about my next step in life and offering great advice. Thank you for being an amazing geochemistry teacher and advisor. v Rusty Malchow for constantly wrestling to get everything stipped on time, for offering an excellent outside perspective on all of my work, and having a constant love of science and endless positive attitude. Ralf Sudowe for being so patient while teaching a geoscientist health physics, running so many samples for me, and going above and beyond the call of duty. And finally Pamela Burnley, without you this never would have been possible. I cannot thank you enough for taking a chance on me as a student. My life is infinitely better having had you as an advisor and mentor. Thank you for holding my hand in the beginning and allowing me to grow as an independent scientist. You are the mold that every other advisor should be made with. Thank you for being kind, supportive, and truly creating a family within your office.
