摘　　要：This study attempted to identify the level of exposure of 350 subjects to the extremely low-frequency magnetic field(ELF-MF).The occupational group showed significantly high levels of ELF-MF in every exposure indicator during work and transportation(p<0.05).About 11%and 6%of the members of the occupational group were exposed to over 2mG and 4 mG,respectively,of ELF-MF during"all"activities.The 24-h ELF-MF exposure levels of the subjects in both groups were analyzed.In the occupational group,for every activity,the percentile for less than 2mG corresponded to 100%of C-4(agriculture),95%of C-1(professional),97%of C-2(engineer,office/sales),81%of C-3(services),85%of C-5(technician,labor management),and 50%of C-6(electrician).In the non-occupational group,the percentile for less than 2mG corresponded to 92%of students,83%of homemakers,81%of the elderly,and 88%of the unemployed.The percentile for over 4mG was 5%for students,homemakers,and the elderly and 13%of the unemployed.Electricians and the unemployed had the highest ELF-MF levels in both groups,respectively.Electricians were exposed to ELF-MF mostly at work,while the unemployed subjects were most affected by the activities classified under sleep and transportation.
