Abstract:
The aim of this study is to determine activity concentrations of natural radionuclides (226Ra, 232Th, 40K and 222Rn) and radiological risks due to the contamination of radionuclides in surface soil in Ho Chi Minh City, Vietnam. Based on the activity concentration of 226Ra in the surface soil, we proposed a method for estimation of the radon concentration in the indoor air. The assessments of radiation dose and excess lifetime cancer risk show that the utilization of surface soils for human residences or routine activities in the studied area poses no risk to the public health.
