Safety of high speed guided ground transportation systems: EMF exposure environments. Summary report. Final report, January-June 1993
The paper presents an overview of American exposure assessments for electric and magnetic fields (EMF) in the frequency range from 0 to 3 kHz. The exposure information available is very limited for all but a few occupations and sources of EMF. Much of the exposure assessment done to date has been conducted in conjunction with epidemiological studies. Beyond the shortcomings of using some of the published epidemiology studies, there are some serious obstacles to conducting definitive extreme low frequency (ELF)-EMF exposure assessments. The lack of a clear definition of what constitutes effective dose hampers the measurement of exposure considerably. Generally, the average power frequency magnetic flux density has been assumed to be the exposure measure of significance, however other parameters of the magnetic field are likely to be relevant as well.
