Abstract

This study aimed to minimize radiation risk in Solok Selatan by analyzing active concentrations of 226Ra, 232Th, and 40K, calculating excess lifetime cancer risk (ELCR) from annual effective dose equivalent (AEDE). Soil samples from seven sites in the Solok Selatan, 0 – 5 cm deep, were tested with a high-purity germanium (HPGe) detector. 232Th concentrations exceeded the established global standard of 30 Bq/kg. In addition, the study included the determination of Radium Equivalent (Raeq), absorbed gamma dose rate (D), AEDE, and ELCR. Annual effective dose ranged from 68.33 to 19.92 μSv/y, below the global average of 80 μSv/y. The ELCR, the critical measure for understanding potential health risks, was 0.27 ± 0.12 x 10-3, under the global average of 0.29 x 10-3. Interestingly, areas closer to the geothermal sources, especially Koto Baru and Sungai Pagu, showed slightly higher natural radioactivity and corresponding effects. These findings emphasize the importance of rigorous surveillance and proactive measures in areas with high radioactivity characteristics. In summary, the results of this study provide important insights into the radiological landscape of Solok Selatan, urgently assisting in addressing potential health risks through informed risk assessment and strategies.
