OBJECTIVETo predict the impact of MF radiation on human health.

METHODSThe vertical distribution of field intensity was estimated by analogism on the basis of measured values from simulation measurement.

RESULTSA kind of analogism on the basis of geometric proportion decay pattern is put forward in the essay. It showed that with increasing of height the field intensity increased according to geometric proportion law.

CONCLUSIONThis geometric proportion prediction model can be used to estimate the impact of MF radiation on inhabited environment, and can act as a reference pattern in predicting the environmental impact level of MF radiation.
