Abstract
In this study, activity of 238U,232Th, and 40K was determined in coal, bottom, and fly ash samples collected from in and around the thermal power plant area of Cuddalore district, Tamil Nadu. The mean activity concentration for 238U, 232Th, and 40K in coal were (45 ± 0.4, 28 ± 0.2, and 145 ± 0.5 Bq kg−1) and ash samples were (103 ± 0.5, 31 ± 0.5, and 334 ± 0.6 Bq kg−1), respectively. To assess the radiation hazards, calculated radiological parameters are compared with permissible limits. This result indicates that the indoor (1.15 × 10–3 mSv y−1) and outdoor (0.56 × 10–3 mSv y−1) excess lifetime cancer risk is slightly greater than the permissible limit and cluster analysis was performed to understand the relation between the variables.
