Assessment of natural radioactivity and radiological hazards in rocks from Thiruvananthapuram, Kerala
This study investigates the natural radioactivity levels in Thiruvananthapuram, Kerala, focusing on uranium (238U), thorium (232Th), and potassium (40K) concentrations in rock samples collected from various locations. Rock samples were collected and analyzed using gamma ray spectroscopy with NaI(Tl) detectors to determine activity concentrations and radiological parameters. The results reveal varying concentrations of 238U (5.05 to 200.31 ± 11.85 Bq kg−1), 232Th (5.04 to 632.73 ± 37.44 Bq kg−1) and 40K (556.89 ± 3 2.95 to 2072.2 ± 122.61 Bq kg−1) with mean values of 49.12 Bq kg−1, 257.71 Bq kg−1, and 1451.56 Bq kg−1 respectively. Radiological parameters (Raeq, DR, AED, H(in,out), GI, RLI, ELCR(in, out), AUI, AGEDE) were also calculated. Correlation and ratio analyses further highlight relationships between uranium, thorium, and potassium concentrations, revealing their geological associations and implications for radiological hazards. This study underscores the importance of monitoring natural radioactivity in urban environments to mitigate potential health impacts and ensure public safety.
