The purpose of this study is to investigate the level of ELF-MF emissions from underground cable lines near daycare centers in the metropolitan city of Seoul. We investigated 143 daycare centers from June to September of 2015. In addition, the rate of reduction of ELF-MF levels according to the distance from the line was calculated using simulations. The ELF-MF emission level of 143 daycare centers at boundary point was 1.37 ± 1.75 mG (GM: 0.75 mG) and at direct point was 11.14 ± 17.99 mG (GM:6.05 mG). ELF-MF levels at direct point were 8.13 (arithmetic mean) and 8.06 (geometric mean) times higher, respectively, than that at the boundary point. By analyzing the relationship between ELF-MF and electricity current (A) and operating depth (m), a significant correlation was found between ELF-MF and current (A) and depth (m), at 0.360 (p<0.01) and -0.303 (p<0.05), respectively. The results of the simulation showed that appropriate separation distances showing below 4 mG was 8m and 14m, adjusted mean current (A) and maximum current (A), respectively. The results of the study suggest that a plan should be implemented for the management of ELF-MF in High voltage power-line and Underground cable line areas, through a broad and detailed survey and risk communication.
