摘要

本研究评估了印度拉贾斯坦邦Sawai Madhopur地区地下水中的铀浓度。季风前铀活度为0.01 ~ 9.7 Bq L−1，季风后铀活度为0.003 ~ 7.5 Bq L−1。使用危害商数、终生平均每日剂量和各年龄组的过量癌症风险来评估化学和放射风险。在部分地点，摄入剂量超过了世卫组织100 μSv年- 1的指导值，危害商超过1，表明存在潜在的化学毒性。然而，终生癌症风险和年有效剂量仍低于阈值。空间和季节变化突出了局部健康风险，强调需要定期监测和有针对性的水安全管理。图形抽象

Health risk study of groundwater uranium and terrestrial gamma radiation in Sawai Madhopur, Rajasthan (India)

This study evaluates uranium concentrations in groundwater from Sawai Madhopur district, Rajasthan, India. Uranium activity ranged from 0.01 to 9.7 Bq L⁻¹ pre-monsoon and 0.003 to 7.5 Bq L⁻¹ post-monsoon. Chemical and radiological risks were assessed using hazard quotient, lifetime average daily dose, and excess cancer risk across age groups. At some sites, ingestion doses exceeded the WHO guidance value of 100 μSv year⁻¹, and hazard quotients surpassed unity, indicating potential chemical toxicity. However, lifetime cancer risk and annual effective dose remained below thresholds limits. Spatial and seasonal variability highlight localized health risks, emphasizing the need for regular monitoring and targeted water safety management.
