Radon: A Tracer for Geological, Geophysical and Geochemical Studies

This book reviews all the major research accomplishments and summarizes the different applications of radon. It serves as a solid reference book for researchers who are interested in the U-series radionuclides and noble gases as tracers and chronometers. Radon has been widely utilized as a powerful tracer to quantify a number of processes that include gas exchange rates between air and water, submarine groundwater discharge in coastal waters, water exchange between rivers and lakes, ocean circulation, hydrocarbon and uranium exploration. It is also used as an atmospheric tracer for the identification and quantification of air masses and as a tool for earthquake prediction, etc. A significant portion of the book presents state-of-the knowledge on indoor-radon-related health issues. Applications of the decay-series of Rn-222 are presented in a chapter. It serves as a reference and a state-of-the-art resource for researchers who want to learn the different applications of radon in Earth systems.

Dr. Mark Baskaran is a tenured Full Professor in the Department of Geology at Wayne State University (Detroit, Michigan). He received his Ph.D. in Physics from Physical Research Laboratory (PRL), a premier research institution in India. After his Ph.D., he spent 2 years at PRL as a postdoctoral fellow before he moved to the Institute of Marine Science at the University of Alaska (Fairbanks, Alaska). After a year, he joined Texas A&M University (Galveston, Texas) where he taught introductory Physics and Geology courses at the Department of Marine Sciences, while conducting research related to atmospheric fluxes of radionuclides, mobility of radionuclides in groundwater, scavenging and particle cycling in marine environment and dating of recent sediments and carbonates. After his eleven year career as a teacher and researcher in Texas, he joined Wayne State University where he became a tenured Full Professor in 2007. He teaches both introductory level courses in Oceanography, Meteorology, and Physical Geology as well as upper level courses including Chemical Fate and Transport in the Environment, Nuclear Geology and Environmental Geochemistry.

Prof. Mark Baskaran has published over 130 peer-reviewed articles (with over 5,100 Google Scholar cumulative citations, h-index 43 in February 2016), most of which are related to the applications of isotopes as tracers and chronometers in Earth systems. He edited a two-volume Handbook entitled "Handbook of Environmental Isotope Geochemistry" with forty articles contributed by eminent scholars in the field in 2011, published by Springer. He spent three months as a Senior Fulbright Scholar at Ege University (Izmir, Turkey) in 2015. He has given invited and plenary talks/seminars at over sixty national/international conferences, workshops, universities and research institutions around the world.

Dr. Baskaran's research work includes all subsystems of the Earth system. Most of his work involved collaboration with a large number of researchers from universities and institutions around the world. His work with marine systems (estuarine, coastal, shelf and open-ocean) on the investigations of particular organic carbon export, particle cycling and remineralization and colloidal thorium scavenging in the Arctic Ocean, Gulf of Mexico, North Atlantic and East Pacific were funded by several funding agencies in the U.S. that include the National Science Foundation (NSF), National Oceanic and Atmospheric Administration (NOAA), and the Department of Energy (DOE). His currently funded ongoing research is to investigate sedimentation and sediment dynamics in dams and other freshwater systems. He has been funded by NSF as a part of the U.S. GEOTRACES group in all four phases (Intercalibration, North Atlantic, East Pacific and Western Arctic Ocean sections). He has served as a Chief Scientist in six major oceanographic expeditions in the Gulf of Mexico and Arctic Ocean.

He convened a National Workshop entitled "Recent Changes in the Biogeochemistry of the Great Lakes System" in March 2013 at Wayne State University. He also had convened a number of sessions and meetings at both national and international conferences and workshops.
