Electromagnetic fields (EMFs) are invisible fields of energy that are emitted by electronic devices. All electronic devices produce some amount of EMF radiation, including cell phones, microwaves, computers, televisions, and power lines.
The amount of EMF radiation that is emitted from a particular device varies from device to device. There are two different types of EMF radiation: Extremely Low Frequency (ELF) and Radio Frequency (RF). Although both ELF and RF are types of EMF radiation, they are produced in different ways and have different health effects.
ELF is produced by the flow of electricity in appliances, wiring in the walls, and the power grid. RF is produced by transmitting signals through an antenna.
An EMF shield is a device that blocks or deflects EMF radiation. There are a variety of different types of EMF shields, including shields for your home and shields for your phone or laptop. EMF shields vary in cost and effectiveness. Some shields are more effective at blocking EMF radiation than others, and some shields are less expensive than others. If you are concerned about EMF radiation, there are a few different types of EMF shields you can use. You can use home shields to protect yourself from EMF radiation from appliances and electronics in your home. You can use phone shields to prevent EMF radiation from reaching your body when you are using your phone. You can also use laptop shields to prevent EMF radiation from reaching your body when you are using your laptop.
