Table 6. 2. Upper action values for exposure to magnetic fields from 1 Hz to 300 GHz

Frequency range, f	Upper action value for magnetic flux density (B) [µT] (RMS)
1 Hz ≤ f < 3 kHz	3.0 x 10^-5 /f
3 kHz ≤ f < 10 MHz	100
10 MHz ≤ f < 400 MHz	0.2
400 MHz ≤ f < 2 GHz	1.0 x 10^-5 x f^1/2
2 GHz ≤ f ≤ 300 GHz	0.45

Note 6.2-1: f is frequency in hertz [Hz].

Note 6.2-2: The action values for exposure to magnetic fields are Root-Mean-Square, RMS values equivalent to peak values divided by √2 for sine-shaped fields. As regards fields that are not sine-shaped, the exposure assessment shall be carried out based on the weighted peak method (filtering in the time domain).

Note 6.2-3: Action values for exposure to magnetic fields represent maximum calculated or measured values at the employee's body position.
