摘要

The present study was performed in Ghuttu window of Garhwal Himalaya, India. The average radon level in water was 4.61 ± 1.40 Bq L−1. The corresponding average annual effective ingestion dose was 9.68 ± 2.94 µSv y−1, while inhalation dose for organs (lungs and stomach) was found 1.66 ± 0.50 µSv y−1. Additionally, the total annual effective dose was estimated as 23.59 ± 7.16 µSv y−1. The anomalous change in radon concentration indicates the significant impact of the tectonic characteristics of the area. Radon concentration and estimated doses fall well below the safety limit prescribed by AERB and WHO. Low values of excess lifetime cancer risk (ELCR) from radon exposure indicate no significant health threats in the area.
