Old Computer Monitors Electromagnetic Emissions Fields Radiation

old computer monitors Old Computer Monitors Electromagnetic Emissions Fields Radiation

Your computer monitor contains what is called a flyback transformer which controls electron beams to produce the image you see on the screen. The transformer produces "very low frequency" (VLF) electromagnetic radiation. All electronic components including omputers emit "extremely low frequency" (ELF) electromagnetic fields. These ELF fields are produced by every appliance and piece of office equipment that runs on electrical current.

Various efforts have been made to avoid or suppress the result of such interference, but such efforts have been found to be inconvenient and/or expensive to implement or both. But as of present The United States government has not set any limits on the amount of electromagnetic emissions from computers.

It has been found in the past that interference from stray signals can be avoided by encapsulating leads in sheaths of RFI (radio frequency interference shielding) material, or by determining the strength of nearby stray signal fields and then moving all such nearby sources to a physical distance from the leads that has been calculated to prevent possibility of undesired signals being picked up by electromagnetic induction. It can be seen, readily, that such preventive methods and techniques are indeed costly and inconvenient. Other attempts to reduce or avoid interference from stray signals have involved the use of ferrite cores.

Scientists have long known that exposure to ionizing radiation (high frequency electromagnetic energy) like that associated with X-rays and gamma rays can cause cancer. However, there is an open question about the long-term effects of the lower frequency, less powerful non-ionizing radiation associated with computers and microwave ovens and the extremely low frequency electromagnetic fields associated with electrical current.
