Bioinitiative 2012 recommended exposure limit conversion explained by Alasdair Philips and Per Segerbäck
0.034 V/m for a CW (constant, or more usually continuous, and unmodulated with data in any form) signal. Could pulse higher if pulsed with gaps when it is off. This is the general conversion.Average Power (as for ICNIRP and FCC normal rule comparisons) = 3 µW/m^2
It makes a much larger difference to the average power but not to the V/m (power is proportional to V/m squared)
0.034 V/m for a CW signal. Could pulse higher if pulsed with gaps when it is off. This is the general conversion.
0.07 V/m if it were 25% on and 75% off over time (it is a square-root law and not linear)
Average Power (as for ICNIRP and FCC normal rule comparisons) = 1.5 µW/m^2
0.1 V/m if it were on for 10% and off for 90% of the time.Average Power (as for ICNIRP and FCC normal rule comparisons) = 0.3 µW/m^2
So 3-fold for V/m and 10-fold for power.
The (next-up.org) table has some slight problems.
It should be stated that for the relationships between the columns to be valid, the levels must be measured in the "far field".
Also, the unit in the left column is dBm. dBm is not used for levels of EMF (the power density), but for power.
(E.g. power dissipated in the 50 ohm receiver input impedance. 0 dBm is 1mW received. Unless you know the antenna area or antenna factor you do not know the corresponding field level).
with complex discussion for the curious:

I need confirmation concerning the BioInitiative 2012 recommendations.
What does 0,0003 uw/cm2 equal in volts per meter?
