Abstract Objective To monitor total α and total β radioactivity levels of ground water in Shenzhen from 2010 to 2016.Methods The measurement was done according to "Standard test method for drinking water"(GB 5750. 13-2006).Results The activity concentration of total α and total β were in the range of (2.2±1.1~118.8±7.8)×10-3Bq/L and (11.0±3.2~615.0±20.1)×10-3Bq/L; The percapita annual effective dose due to drinking-water in Shenzhen was (1.83~4.91)×10-3mSv/a and (2.41~3.85)×10-4mSv/a. The results are in line with national standards.Conclusion The level of total α and total β of ground water in Shenzhen fall in the range of normal background.
