EMF’s & Non-Ionising Radiation
Non-ionising radiation (NIR) is the term used to describe the part of the electromagnetic spectrum covering two main regions, namely optical radiation (ultraviolet (UV), visible and infrared) and electromagnetic fields (EMFs). EMF’s are produced wherever electricity is used, in the home, office, or anywhere else. Electric fields are produced by voltage and magnetic fields by current. Most of us get most of our exposure from distribution wires, either buried along the street or on wood poles, and from wiring in our homes. We also get short-duration higher field exposures when we pass close to electrical appliances such as fridges, microwaves, computers, etc. The UK Government set exposure limits for EMFs and the electricity industry complies with these. The limits are designed to prevent all established effects of fields on the body.
