DMC STEM Lecture: Radiation in Geological Time & Space

Del Mar College STEM Lecture titled "Radiation and Radioactivity in Geological Time and Space" The natural background of ionizing radiation on Earth varies spatially by two orders of magnitude at present. Claims of risk to organisms from exposure to the upper limits of the natural background range remain unsupported by observed evidence. A broader understanding, beyond just radiometric age-dating, of radioactiviy must become a part of literacy of all of the sciences. Geology is well suited to play a major role in this effort. Retired employee of the Waste Isolation Pilot Plant in Carlsbad, New Mexico, Norbert T. Rempe offered this presentation at Del Mar College. Presented by the Natural Sciences Department. Recorded on January 22, 2016.
