Inter-laboratory comparison of numerical dosimetry for human exposure to 60 Hz electric and magnetic fields

In recent years, with the availability of high resolution models of the hum an body, numerical computations of induced electric fields and currents hav e been made in more than one laboratory for various exposure conditions. De spite the verification of computational methods, questions are often asked about the reliability of these data. In this paper, computational results f rom two laboratories that presented data in compatible formats are compared , supplemented with additional data from the third laboratory. Two exposure s to uniform fields at 60 Hz are evaluated. The human body models used in t he computations are different and so are the computational methods and code s. There are some differences in the conductivity values used for some of t he tissues, as well. The results of the comparison confirm that these data are reliable, as the overall agreement is reasonably good and the differenc es can be rationally explained. This comparison also underscores the import ance of accurate data on the dielectric properties of tissues. (C) 2000 Wil ey-Liss, Inc.
