EMF Values for Sample Appliances

Sample EMF Values (mG) for ELF/VLF sources

The following EMF table shows sample low frequency (magnetic) values only.

These devices are mainly powered by mains electricity whose frequency was 50/60 Hertz. Non-mains-powered devices are also included in this table if they produce EMF values within the Low-Frequency range, for example: cellphone, laptop computer.

The Low Frequency range includes so called Extremely Low Frequency (ELF)  and Very Low Frequency (VLF) ranges.

Devices such as cellphones and microwave ovens are included in this table because they produce substantial low frequency radiation in addition to Radio / Microwave radiation. (The Radio/Microwave values are not shown in this table).

These are sample values. Your equipment may produce different EMFs.
