Despite increasing public concern following mass media coverage regarding the risk of radon to human health and the need to control it, there remains a lack of infrastructure for measuring and mitigating radon. Against this backdrop, this paper is part of an effort to formulate an environment-management framework that can help resolve environmental issues relating to radon, ease fears regarding the associated risks, and provide radon-specific quality services. This study aimed to suggest locally applicable measures for training experts specializing in the fields of measuring and mitigating radon mainly based on US cases in which radon measurement and mitigation certification programs have been systematically run and supervised. Given the lack of both awareness on radon and experts in Korean circumstances, it is necessary to come up with a scheme to develop a radon-specific education program and a framework for expert accreditation. Thus, as groundwork for their introduction considering local circumstances, top-down measures led by the relevant department of government-led organizations, which will act as the control tower, should first be implemented to best utilize the insufficient human resources in this area. In addition, more systematic and detailed educational programs and an expert certification system need to be developed in accordance with the established foundations, and to support their consistent operation, a relevant administrative system should be constructed.
