REFERENCE LEVELS
The reference levels are obtained from the basic restrictions by mathematical modeling using published data (Dimbylow 2005, 2006). They are calculated for the condition of maximum coupling of the field to the exposed individual, there by providing maximum protection. Frequency dependence and dosimetric uncertainties were taken into account. The reference levels presented consider two distinct effects and approximate a combination of the induced electric fields in the brain relevant for CNS effects, and the induced electric fields in non-CNS tissues anywhere in the body, relevant for PNS effects (i.e., at 50 Hz, the factor used to convert the basic restriction for CNS effects to an external magnetic field exposure is 33 V m1 per T, and for PNS effect 60 V m1 per T. An additional reduction factor of 3 was applied to these calculated values to allow for dosimetric uncertainty).
