Vectoring towards buried high-purity quartz metapegmatites using low-elevation radiometric and soil geochemical surveying: Method validation in Tysfjord, Norway | This study validates an MS-350 gamma-ray spectrometer as a powerful tool for detecting buried high-purity quartz-bearing metapegmatites in Tysfjord, Norway. Compared to soil geochemistry, gamma ray surveys deliver higher resolution, faster data collection, and better spatial coverage. | 2025 | |
Drone-based radiometric surveys provide high-resolution mine waste characterization | Drone-mounted gamma-ray sensors offer a high-resolution, efficient method for characterizing mine waste and detecting geochemical anomalies related to uranium, thorium, and potassium. The mine waste in the study originates from copper mines and waste material was investigated for remining of REE minerals with a drone-borne MS-350. The measured levels of K, U, and Th appeared to be proxies for the content of rare earth elements (REE). | 2025 | |
Upscaling ground-based backpack gamma-ray spectrometry to spatial resolution of UAV-based gamma-ray spectrometry for system validation | This study demonstrates the effectiveness of using UAV-based gamma-ray spectrometry (GRS) for mapping uranium contamination at former mining sites, specifically by validating airborne data against traditional ground-based backpack measurements. Geostatistical upscaling to a large dataset from Uzbekistan, demonstrated that UAVs can accurately measure absolute radionuclide activities despite their lower spatial resolution. The results show that UAVs provide a reliable and efficient means of delineating uranium distribution in complex environments. | 2024 |
