  • In order to assessment of Natural Radioactivity and Associated Radiation Hazards in soil samples, activity concentration of naturally occurring radionuclides was measured by using a gamma spectrometer with a high energy resolution HPGe detector. The average radioactivity concentrations of 226Ra, 232Th and 40K in the surface layers (5‑30 cm depth) collected from Khammuan province, Laos, were 32.57± 3.35 Bq.kg-1,41.10±3.04 Bq.kg-1 and 295.07± 17.36 Bq.kg-1respectively. From the activity concentration of 226Ra,232Th and 40K, we derived the parameters using the assessment of the radiological hazard from exposure to these soil samples. The average absorbed dose rate of all measured samples...

  • We have determined activity concentrations in 33 soil samples collected from Bolikhamxay Province, Laos. The activity concentrations of the natural radionuclides 226Ra,232Th and 40K in soil samples were measured by a gamma spectrometer with a HPGe detector. The average activity concentrations of the natural radionuclides 226Ra, 232Th and 40K are 43.8 ± 5.6, 57.0 ± 7.3 and 426.4 ± 23.1 Bq.kg-1, respectively. The average activity concentrations of 226Ra and 232Th in this work are higher than those of the world average values. Meanwhile, the activity concentration of 40 K is almost the same of the world average value. The estimated average outdoor annual effective dose (E) and radium eq...
