Abstract

Daily preexposure and postexposure mass measurements of 65 rats (young males and females, old males) were recorded during exposure to a 0.1 mT, 60 Hz sinusoidal magnetic field, a proprietary pulsed wound healing field, pulsed electromagnetic field, (PEMF), or their control fields for 4 h/day for 21 days. Statistical analysis of mass changes over time showed that young rats exposed to PEMF lost more mass and recovered it more slowly compared to controls (2-4% more loss) than did older PEMF exposed rats or any 60 Hz exposed rats. We conclude that daily preexposure and post-exposure mass measurements are needed to adequately assess the effects of electromagnetic fields on body mass.
