Pilot: Center for Appalachian Research in Environmental Sciences: UAV-based Aeroradiometric Mapping to Understand Geologic Controls on Intraformational Radon Variability: Towards an Improved Rational Basis for Indoor Radon Potential Microzonation

UAV-based Aeroradiometric Mapping to Understand Geologic Controls on Intraformational Radon Variability: Towards an Improved Rational Basis for Indoor Radon Potential Microzonation Abstract The Kentucky Geological Survey is seeking funds to support acquisition of a UAV-mountable gamma spectrometer and to perform a limited pilot study demonstrating utility for microzonation of radon-related soil radionuclides for future radon mitigation and education. In combination with UAV-mounted LiDAR and ground-based in-situ soil-radon measurements, the spectrometer data will be used to evaluate potential variation of soil radionuclides (and by proxy soil radon) in the vicinity of mapped faults and observed karst sinkholes. The results of these local surveys will be evaluated quantitatively for uncertainty and the results used to inform future radon potential mapping in Kentucky and elsewhere.
