The exposure levels set for this tester are based on the ICNIRP (Interna-
tional Commission on Non-Ionizing Radiation Protection) Guidelines.
Basic restrictions apply to current density, SAR and power density.
Threshold values have been set on the levels of these physical quanti-
ties that affect human health (for example, headaches). Occupational
exposure level is 1/10 and general public exposure level is 1/50 of this
threshold value. (See figure below.)
The ICNIRP Guidelines provide reference levels - for assessing the
basic restrictions - that state the magnetic field and electric field levels
when the coupling of the human body, magnetic field and electric field
are at maximum (coupling factor 1).
*: Specific energy absorption rate
As can be inferred from the above, there is a margin, a safety factor
(reduction factor) between the exposure level measured by this tester
and the threshold values in the basic restrictions. Thus an exposure
level of 100% measured by this tester does not mean to affect the
human body.
