A large number of studies have shown that indoor radiation can damage our digestive organs, reproductive system, hematopoietic system and nervous system. In this topic, aiming to master the indoor environmental radioactivity level and the levels of radiation, the feasibility experiment plans with both appropriate measuring method and measuring instrument are designed to measure γ-radiation dose rate and Radon concentration of student dorm actually. Meanwhile, the radiation dose of students can be estimated through monitoring data, and the results can be evaluated to judge the pros and cons of living conditions. Besides, the indoor radiation monitoring results with the theory were compared, so that students can understand the radioactivity and radiation hazards from the data.
