The exposure limits according to the ICNIRP depends on frequency, of course.
>From 1hz to 300hz the Occupational limits are like 20kV/m for E-Field and 40k to 200uT. >From 3khz to 10Mhz the limit is 170V/m (100uT). For the General Public (up to 24 hours a day), the limit is 83V/m (27uT). For example.
