The Electromagnetic Spectrum

EMFs are typically grouped into one of two categories by their frequency:

Non-ionizing – low-level radiation, generally harmless

Examples:

• Microwave ovens
• Computers
• House energy smart meters
• Wireless (wifi) networks
• Cell Phones
• Bluetooth devices
• Power lines
• MRIs

Ionizing – high-level radiation, potentially harmful

Examples:

• Sunlight
• X-Rays
• Some Gamma Rays
