Natural radioactivity and radiological hazards in soil samples in Savannakhet province, Laos

This paper presents the evaluation of natural radioactivity and radiological hazards of the terrestrial naturally occurring radionuclides of 226 Ra , 232 Th and 40 K in Savannakhet province, Laos. The activity concentrations of 226 Ra , 232 Th and 40 K are in the range of 6.6–73.6, 3.8–113.8 and 13....

Zusammenfassung:This paper presents the evaluation of natural radioactivity and radiological hazards of the terrestrial naturally occurring radionuclides of 226 Ra , 232 Th and 40 K in Savannakhet province, Laos. The activity concentrations of 226 Ra , 232 Th and 40 K are in the range of 6.6–73.6, 3.8–113.8 and 13.6–906.4 Bq kg - 1 , with the average values of 22.4 ± 2.1 , 30.8 ± 2.9 and 211.6 ± 16.5  Bq kg - 1 , respectively. The average radium equivalent activity Ra eq is calculated as 82.8 ± 9.7  Bq kg - 1 , which is smaller than the safety limit of 370 Bq kg - 1 . Radiological hazard indices have also been evaluated in comparison with the world average values.
