Gamma-Ray Spectrometry of Soil Samples From a Pilot Site of Uranium Anomaly in the Sahel Region of Burkina Faso
The natural radioactivity level has been determined in a pilot site located at Solhan, in the Sahel region of Burkina Faso by means of gamma-ray spectrometry in soil samples collected at a depth of 40 cm. The activity concentrations are estimated for 238U (range from 181.89±3.62 to 191.37±3.71 Bq·kg...

| description | The natural radioactivity level has been determined in a pilot site located at Solhan, in the Sahel region of Burkina Faso by means of gamma-ray spectrometry in soil samples collected at a depth of 40 cm. The activity concentrations are estimated for 238U (range from 181.89±3.62 to 191.37±3.71 Bq·kg−1), 232Th (range from 44.92±2.96 to 48.40±3.25 Bq·kg−1), and 40K (range from 215.11±6.13 to 238.60±6.52 Bq·kg−1). The concentration of 238U present in these soil samples is five times higher than the world average, while the concentration of 232Th is almost the double of the world average. However, the concentration of 40K is particularly low in the study area, being almost half the world average. Additionally, calculations of the Th/K and Th/U ratios indicate the presence of a clay soil and insoluble uranium in the study area. These results made it possible to assess the radiological hazards on the human health. This allowed us to note that the average values of absorbed gamma dose rate in air (124.14 nGy·h−1), internal hazard index (1.24), annual effective dose equivalent (0.76 mSv·y−1), and excess lifetime cancer risk 5.34×10−4 are well above the maximum recommended limits. Only the mean values of radium equivalent activity (271.39 Bq·kg−1) and external hazard index (0.73) remain within the acceptable limit. |
