The objective of this paper is to investigate the dependency of dosimetric compliance assessments on applied methodology and anatomical modeling for human brain tissues exposed to low-frequency (LF) magnetic fields. This study has addressed several critical open questions pertaining to the LF numerical dosimetry of B-field induction, e.g., the impact of discretization errors on the spatially averaged E-fields, the effect of tissue conductivity contrast on peak E-field intensity, and the consistency and applicability of the ICNIRP and IEEE exposure limits.

The scientific and technical impact of this study can be summarized as:

  • Frequency scaling should be applied with caution when significant variations in tissue conductivity contrast with respect to frequency shifts are expected.
  • The peak induced E-field derived in a homogeneous head model is not conservative enough to represent the worst-case induced E-field in the human brain.
  • Reference levels of the IEEE C95.6 [2002] standard can be in contradiction with the basic restrictions by a factor of more than 5, and revision of the limits is recommended.
  • An arbitrary filtering approach, such as the 99th percentile value (ICNIRP 2010), could lead to significant underestimation of the peak E-field and may significantly impair the reproducibility of exposure assessments.
  • Spatial averaging with a grid size of 0.5 mm or smaller sufficiently reduces the impact of artifacts regardless of tissue size, and it is, therefore, recommended to replace the 99th percentile with such a requirement.
