Methods: This study uses radon data measured in the subway stations from 2015 to 2016. Of the total of 4,643 cases, 4,231 cases were analyzed excluding the 412 cases where the values were below 300Bq/m3. Results: Cost-Benefit analysis was done on the results of the field survey on subway work sites. At the exposure level of 400Bq/m3, the ratio between the cost and the benefit was highest at 1 : 1.81(the cost was KRW 1,398,568,032, while the benefit KRW 2,5248,772,841). At the exposure level of 600Bq/m3, the ratio of cost and benefit was 1: 1.80, at 300Bq/m3 it was 1.72, at 800Bq/m3 it was 1.71, at 200Bq/m3 it was 1.54, and at 100Bq/m3 it was 1.40. Conclusions: Radon management in the workplace provides economic benefits and appropriate reduction strategies are needed. In addition, it is necessary to establish and distribute radon exposure assessment procedures and guidelines for the safety and health of employees when exceeding the exposure standard, and guidelines for radon management in the workplace should be established.
