Research on electromagnetic fields from magnetic resonance imaging, combining strong static fields with RF pulses.
MRI (Magnetic Resonance Imaging) machines represent one of the most intense sources of EMF exposure you'll encounter in medical settings. These diagnostic devices generate powerful static magnetic fields up to 60,000 times stronger than Earth's magnetic field, combined with radiofrequency radiation in the 64-300 MHz range to create detailed images of your body's internal structures. While an MRI scan typically lasts 15-90 minutes, the EMF exposure during this period is extraordinarily high compared to everyday sources.
