Abstract

Abstract The present work investigated the activity concentrations of natural radionuclides 226Ra, 232Th and 40K in beach sand samples along coastal Kerala including high background radiation area. The activity of 232Th ranges from below detectable level to 23029.9 Bq kg-1 with a mean value of 2660.2 Bq kg-1 for 0–10 cm depth interval. For 10–20 cm depth, the 232Th activity ranged from below detectable to 4452.2 Bq kg-1 with a mean value of 815.5 Bq kg-1. The variation of 226Ra activity with depth is parallel with the 232Th activity distribution in beach sand. Its activity varied from below detectable to 5169.5 Bq kg-1 with a mean value 487.6 Bq kg-1 at 0–10 cm depth. For 10–20 cm depth interval, the 226Ra activity ranges from below detectable to 1823.6 Bq kg-1 with a mean value 296.0 Bq kg-1. Similarly the activity varies from below detectable to 1826.6 Bq kg-1 with a mean value of 211.0 Bq kg-1 for a depth interval of 20–30 cm. The activity of 40K at different depth is also discussed. Statistical analysis of radioactivity was also carried out. The results of these investigations are presented in this paper.
