Long-term effects of 60-Hz electric vs. magnetic fields on IL-1 and other immune parameters in sheep: Phase 4 study. Final report
- Veterans Affairs Medical Center, Portland, OR (United States)
This study was designed to assess the effect of exposure to long-term low-frequency electric and magnetic fields (EMF) from an environmental 500-kV transmission line on immune function in sheep. The primary hypothesis tested was that the reduction in IL-1 activity observed in two previous short-term studies (9 months) was due to exposure to EMF from this transmission line. The secondary hypothesis was that long-term exposure (27 months) would impact immune function and animal health. To characterize the components of the EMF environment responsible for the previously observed reduction in IL-1 activity, the experiment was designed not only to examine the effect of exposure to electric and magnetic fields, but also to examine the magnetic field component alone. This was done by constructing a third pen (MF) which was shielded with wire to effectively eliminate the electric field while not significantly affecting the magnitude of the magnetic field.
