Objective To investigate indoor radon concentration in Xining City. Methods Radon continuous monitor was used to monitor indoor buildings of different ages and different structures in 4 districts of Xining City. Results The indoor radon concentration in Xining ranged from 6.7 to 95.55 Bq / m3, and the average indoor radon concentration level was 31.41 Bq / m3. Conclusion The indoor average radon concentration in Xining is lower than the average level of indoor radon concentration in China. The indoor radon concentration increases with the approaching of the building age, and the indoor radon concentration in winter and spring is obviously higher than that in summer and autumn
