What is EMF?
• Electric and magnetic fields (EMF) are sometimes jointly referred to as electromagnetic fields, or EMF. EMF is found wherever there is electricity, whether it is wiring, appliances, computers or power lines. • Exposure to the field is determined by how strong the field is at its source (the blender, a hair dryer. a computer, a power line) ; how far away you are from the source and how long you stay near the source. The strength of EMF drops quickly as you move away from the source. • Magnetic fields are all around us, although generally higher near commonly used electrical appliances including power saws, microwave ovens and hair dryers. The magnetic field associated with overhead transmissions lines is similarly low and drops quickly as one moves away from power lines.

We treat those co
