To know more please investigate this aspect of our lives yourself.
The following EMF table from (http://emwatch.com/emf-values-for-sample-appliances/) 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.
EMF in milligauss at distance
|6 Inch||1 Ft||2 Ft||4 Ft|
|Baby monitor *||6||1||0||0|
|Cellphone (VLF only) Contact:20mG *||5||2||0||0|
|Computer monitor (CRT)||14||5||2||0|
|Computer monitor (LCD flat)||1||0||0||0|
|Computer (desktop) *||3||1||0||0|
|Computer (laptop) * Contact:20mG||5||1||0||0|
|Cooking range / Hob||30||8||2||0|
|Electric Blanket At 2.5cm/1″: 20mG|
|Flourescent Light *||40||6||2||0|
|Garbage disposal unit||80||10||2||0|
|Hi Fi / CD player / Tuner etc||1||0||0||0|
|Microwave Oven * (VLF only)||200||40||10||2|
|Power supply (UPS)||90||25||3||1|
|Printer * (desktop)||3||1||0||0|
|TV (with CRT-type screen)||30||7||2||0|
* All the devices marked by an asterisk may produce two kinds of EMF: Low frequency EMF and Radio/Frequency EMF. The values shown in this table are for Low Frequency EMF (magnetic) only.
Cell phones emit ELFs from different points of the cell phone even when you are not talking on it or using it in any way.
Company A, with the batteries removed, contact 3–50mG, strongest near the antenna. Company A’s battery: 2-3mG.
Company B, with the battery installed and the phone turned on but not using it, contact 3 to >70mG, strongest near the internal antenna.
Be Alert and Balanced : A hundred years ago, the multitude of ELFs that humans are now surrounded by was non-existent. Every electrical device we use especially cell phones, laptop computers, microwave ovens, and any kind of electric blanket, carpet, or pad that you can lie or sit on contributes adversely to your health.
