To realize long-distance electricity transmission

staffs in electric utility need to work long time under high level electromagnetic field.However

excessive exposure will harm human health.Therefore

exposure assessment of electromagnetic field is very important in the development of new energy technologies.For the current exposure assessment methods

the calculation cost of voxel human model is very high

and insufficient attention is paid to the non-uniform electromagnetic field in real working condition.This paper proposes two practical methods for assessing the exposure of non-uniform electromagnetic fields.A realistic human body model is established

and the correctness of the model is verified.Equivalent uniform electromagnetic field is obtained by comparing the maximum electromagnetic field level which people is exposed to and the corresponding induced electric field in human body.The spatial average of exposure through the whole body is determined by arithmetic mean averaging and quadratic mean averaging

respectively.An assessment example of non-uniform magnetic field exposure around air-core reactor is given to demonstrate the effectiveness of the equivalent uniform electromagnetic field approach and the spatial averaging approach in assessing non-uniform exposure based on realistic human body model.
