Low Frequency (Conductivity)

Low Frequency (Conductivity)

The following table contains values for the electrical conductivity for frequencies up to 1 MHz for all tissues, including statistical information on the standard deviation and the spread in the values. The low frequency parameters are based on a combination of the Gabriel dispersion relations1 and a review of the available literature.

Note: The inclusion of new publications, and in particular diffusion tensor image data, leads to substantial changes in several tissue properties (up to factor 2 higher conductivity for several tissues). Noteworthy changes that have occurred can be viewed here.

Mixed: Includes all studies (Across, Along), independent of the measured direction.

Skin: It has been reported that the conductivity of the skin significantly impacts the dosimetric assessment at low frequencies. The values for skin conductivity presented here should be used with caution.
