Objective: Building materials can generate radon in indoor environments. This study aims to assess the radon concentrations of studio apartments around a university. Methods: 25 studio apartments around a University in Gyoungsan, Korea were measured for concentrations of radon. We evaluated the radon concentrations by using short-term continuous radon monitors at the studio apartments around the university, and analyzed the correlation between indoor radon concentration and factors affecting it, such as year of construction. Results: The average concentration of radon was 2.03 pCi/L(75.11 Bq/m3)±1.34 in the studio apartments. This radon level was lower than the radon standard for public use facilities in Korea and US EPA’s standard of 4 pCi/L. However the measured radon levels were much higher than those previously reported in conventional dwellings. There was a statistically correlation between year of construction and radon concentrations in studio apartment buildings. Conclusion: It is suggested that recently built studio apartments might be constructed with phosphogypsum board that features higher radon emissions, and occupants are highly exposed to radon.
