Dosimetry for workplace EMFs at power-line frequencies.

• Description:
  There is an increasing concern that electromagnetic fields (EMFs) at power frequencies may have adverse health effects. A key research need, therefore, has been to establish the mechanisms of bioeffects of the EMFs. An important aspect of this is to understand the coupling of the EMFs to the various tissues in the human body and to compare these with the EMFs that are endogenous to the human body. Knowledge in this area was relatively poor, since only simple saline-filled and metal-coated idealized models had mostly been used. The focus of this project has, therefore, been to obtain internal electric fields and induced current densities in heterogeneous, anatomically based models of the human body for a variety of realistic exposure conditions, including near-field sources such as a power drill, etc. Toward this end we have also developed a millimeter-resolution anisotropic MRI-based model of the human body which has been used to pinpoint the regions of the highest induced electric fields and current densities in the body for the various sources.
