Basic ICNIRP guideline limits for time-varying electromagnetic fields.

Exposure characteristics	Frequency range	Current density; (mA/m^2)	Internal electric field (V/m)	Whole-body average SAR; (W/kg)	Local SAR (head and torso); (W/kg)	Local SAR (limbs); (W/kg)
Occupational exposure	10 kHz to 100 kHz			-	-	-
	100 kHz to 10 MHz			0.4	10	20
	10 MHz to 10 GHz	-	-	0.4	10	20
Public exposure	10 kHz to 100 kHz			-	-	-
	100 kHz to 10 MHz			0.08	2	4
	10 MHz to 10 GHz	-	-	0.08	2	4
