مستخلص:	Soil is an important source and medium of radionuclides, and the content of radioactivity in soil is crucial for radiological impact evaluation. In this study, twenty soil samples in the high background natural radiation area of Yangjiang, China were collected and analyzed for ²²⁶ Ra, ²³² Th, ⁴⁰ K and ¹³⁷ Cs concentrations in order to evaluate the radiological health risk in the area. Results showed that the average activity concentrations of ²²⁶ Ra, ²³² Th and ⁴⁰ K are 66 Bq/kg, 109 Bq/kg and 211 Bq/kg, respectively. The calculated radiological parameters of radium equivalent activity (Ra eq ), absorbed dose rate (D), annual effective dose equivalent (AEDE), internal and external hazard indices (H in and H ex ) show a large variation at different sampling sites. Additionally, the elemental oxidation composition and ⁴⁰ K/K mass ratio in the soil were analyzed to further augment the background information of the high background radiation area in Yangjiang.
