Electromagnetic fields

Electromagnetic fields (EMFs) arise whenever electrical energy is used. So for example, EMFs arise in our home from electrical appliances in the kitchen, from work processes such as radiofrequency heating and drying and in the world at large from radio, TV and Telecoms broadcasting masts and security detection devices.

The guide to the Control of Electromagnetic Fields at Work Regulations 2016 and information on exemptions is available.
