The Study Analyzed Soil Samples from the Bellary District of Karnataka, India, and Revealed Activity Concentrations of 238U, 232Th, and 40K

Abstract

Research has been conducted to examine the depth profile distribution of natural occurring radioactive elements, including ⁴⁰K, ²³²Th, and ²³⁸U, in the soil of the Bellary District of Karnataka, India. Gamma-ray spectrometry techniques were employed to evaluate samples from five talukas in the Bellary districts employing 4˝x4˝ NaI (TI) Scintillation detectors. According to depth profiles and the distribution of naturally found radionuclides, the soil samples exhibit an amount of ²³⁸U at 91.81 Bq/kg, with the greatest concentration at 189.74 Bq/kg. But the concentration of ²³²Th also varies, ranging from 106.51 to 303.55 Bq/kg. Between 604.88 and 1080.29 Bq/kg, the range corresponds to a ⁴⁰K activity concentration. In these areas, there has been no evident correlation between the quantities of ²³⁸U and ²³²Th in a soil surrounding the residences. ⁴⁰K/²³²Th and ⁴⁰K/²³⁸U proportion forecasts were also made using surface-level samples, which could not have included identical ratios as the ones being examined.
