Natural radioactivity in soils of Elephant hills, Tamilnadu, India

The aim of the present work is to determine the activity concentrations of natural radionuclides and the associated radiation hazards in soils of Elephant hills, Tamil Nadu, India using gamma-ray spectrometry. The average activity concentrations of 238 U, 232 Th and 40 K are 52, 48, and 840 Bq kg −1...

Description
Summary:The aim of the present work is to determine the activity concentrations of natural radionuclides and the associated radiation hazards in soils of Elephant hills, Tamil Nadu, India using gamma-ray spectrometry. The average activity concentrations of 238 U, 232 Th and 40 K are 52, 48, and 840 Bq kg −1 respectively. The average dose rate of 89 nGy h −1 is nearly 1.5 times higher than the outdoor world average, but the average annual effective dose equivalent (AEDE) is less than the recommended limit of unity. Pearson correlation analysis indicates that 40 K does not contribute to radioactivity in these soils.
