초록
Objectives: The objective of this study was to conduct risk assessment using indoor radon concentration andexposure times. Methods: The target facilities were military facilities before and after the application of radon reductionprocesses and underground commercial facilities in major subway stations in Seoul. Indoor radon concentrationswere measured by passive sampler. Results: Radon concentrations in 13 military facilities were initially higher than the guidelines, but the levelswere below guidelines after the application of radon reduction processes. Underground shopping mall radonconcentrations near subway stations in Seoul satisfied the guidelines. However, indoor radon effective doses afterradon reduction processes in some military facilities and those in underground shopping malls belonged toInternational Commission on Radiological Protection (ICRP) groups needing control management. Conclusion: Indoor radon management requires risk assessment data that takes into account working time (orresidence time) in addition to management according to concentration guidelines.
