issue that still remains debatable at scientific forums.

The confirmation of age-dependence of dielectric parameters of human biological tissues potentially may contribute on issue whether children should be considered a sensitive group in comparison to adults regarding exposure to microwave electromagnetic fields,

Experimental measurement *in vivo* at most human biological tissues is impossible, thus alternative methodologies have to be considered, few of them mentioned on this chapter.

Extrapolation of obtained experimental results of dielectric parameters of animal bio tissues to humans is considered debatable since animal tissues differ significantly from human tissues, and a detailed and all –inclusive study of animal and human growing curves along with markers along curves should be performed to propose correlation between animal and

human dielectric parameters.
