the printer has radiation.
There are three kinds of printers, namely, stylus printer, inkjet printer and laser printer. The first two basically have no radiation, and laser printers have some radiation, but they are also very small. In terms of radiation alone, computers are bigger than printers.
the scientific definition of electromagnetic radiation is that electromagnetic radiation is composed of electric energy and magnetic energy which are simultaneously transferred in space, and this energy is generated by charge movement. For example, the moving charge from the RF antenna that is transmitting signals will generate electromagnetic energy.
The energy derived from electromagnetic radiation depends on the frequency. The higher the frequency, the greater the energy. Computers, mobile phones, televisions, etc. are all common electromagnetic radiation sources in the family. Like these electrical appliances, the printer will also release certain electromagnetic radiation when it is working.
Precautions when using printers
1. Keep a distance. In order to avoid the influence of electromagnetic radiation, both printers and other electrical appliances should try to keep a distance from them. Generally speaking, people should keep a distance of more than 1 meters from the printer, and then take the documents after printing. Avoid standing by the printer for a long time.
2. Open more windows, and air convection will help reduce the pollution of waste gas and dust particles. If you print frequently or print a lot, it is best to install an exhaust fan or ventilation pipe indoors to dilute harmful particles in time, which is also conducive to the discharge of oxides such as ozone.
3. Don't remove the machine cover casually. The printer cover can block the radiation. When printing, don't remove the cover before printing, and don't touch the high temperature and high pressure parts with your hands.
4. Put green plants. Put several pots of green plants that can absorb dust around the printer and on the desk, such as Hupilan, Asparagus, cactus, chlorophytum, etc., which can reduce indoor dust pollution and radiation.
