Quantification of 222Rn exhalation rates and effective 226Ra content from geological samples across the Kopili Fault Zone, India

AbstractThe study presents measurements of222Rn exhalation rates,226Ra contents and radiological exposure doses of granite, gneiss, shale, sandstone and soil samples across the seismically active Kopili Fault Zone, India using LR-115 (II) track detectors. The granites were found to have higher222Rn exhalation rates than the other types of rocks. The study shows higher222Rn exhalation rates and radiological exposure doses of soil samples collected near the fault than those collected away from the fault. However, the226Ra contents in every geological sample were within the global average value of 40  Bq kg−1 for materials used in common buildings.
