Abstract Objective To investigate the current situation of environmental radioactivity level in Fangchenggang, Guangxi Zhuang Autonomous Region, China, and to provide a basis for the reasonable formulation of environmental radioactivity monitoring and management plan. Methods Through systematic grid layout, the environmental surface gamma (γ) radiation dose rate was measured in Fangchenggang, and its radioactive characteristics, distribution rules, and influencing factors were systematically investigated. Results The dose rate of environmental γ radiation in this city ranged from 6.7 to 231 nGy/h, with a mean value of about 100 nGy/h. Conclusion The investigation results of environmental radioactivity level in this city are consistent with the investigation results (10.7～239 nGy/h) of Investigation of environmental natural penetrating radiation level in Guangxi Zhuang Autonomous Region(1987—1988), indicating that there is no abnormality in the environmental quality in terms of γ radiation in the whole investigation area.
