An EMF survey is a comprehensive assessment of the electromagnetic field (EMF) and radiofrequency (RF) levels within a given property, whether it is your current residence or a potential home you wish to buy or rent.

There are two primary types of EMF found in homes: low-frequency and radio-frequency EMF. Low-frequency EMF originates from sources like electrical power lines, substations, underground cables, household wiring, and various electrical appliances.

The human electromagnetic field has undergone significant changes in recent years. Advances in technology and the rise of wireless communication have exposed us to new and varied forms of electromagnetic radiation. Everyday technologies such as Bluetooth, WLAN, wireless systems, and modulated and pulsed signals, along with time and code division multiplexing, are now a constant part of our environment. High-frequency radiation, commonly known as radio-frequency (RF) and microwave radiation, is typically used for wireless signal transmission.
