The results show ed that the electrom agnetic radiation level in Nanjingm et the re-l evant standards, but som e d istrict were in h igher level. E lectrom agnetic rad iation ofNanjingm ainly cam e from broadcasting andTV transm ission system. Therefore advanced and scientific urban p lan should be des igned when the urban planning.
