Even indoors they occur in DECT phones, Wife networking, wireless, and PC games like Wiki remotes. When a device or facility emits, we speak rather than radiation fields.
Low-frequency alternating electric fields
These fields occur in the electricity, extension cords in the house and out of walls and cupboard. Even if a device is not on, there is tension on the wire and thus electric field.
Charles Livingston Review
Low-frequency magnetic fields
This type occurs in electric motors, underground power cables, electronic devices and other power consuming devices and cabling.
When a device is turned on and consumes power, creates electromagnetic fields.
Inconvenience someone may have some equipment is not only determined by the field strength and field type, but also by the form of the 50 Hz waves, some waves are very different from the ' sinusoidal 'are especially sickening.
There is not enough known why this particular type of waves this effect is susceptible people.
Standards and Guidelines
A measure found in a particular place is compared with a reference value to know whether you are on the safe side. SBM2003 stands for the German construction organic guidelines from 2003.
These guidelines were developed in collaboration with physicians and scientists. Based on thousands of measurements in living and working environments by German construction biologists the knowledge EHS uses the SBM2003 guidelines, which are based on natural physically measurable quantities and apply to long-term exposure.
