Research on EMF from medical imaging and therapeutic devices - MRI machines and other medical equipment.
## Medical EMF Sources: Understanding Exposure in Healthcare Settings When you enter a medical facility for diagnostic imaging or treatment, you're stepping into one of the most electromagnetically intense environments you'll likely encounter. MRI machines, CT scanners, X-ray equipment, and therapeutic devices generate some of the strongest electromagnetic fields found in everyday settings-often thousands of times more powerful than typical household electronics.
