The scanner will produce radiation to the human body when scanning, but this radiation has reached the level of endangering health.
1, no matter what brand of scanner, it is not more radiant than computer mainframe, monitor, soymilk machine and other electrical appliances;
2. Portable mobile phones actually radiate more and have longer contact time;
Sunbathing is actually receiving radiation. Radiation is divided into ionizing radiation (industrial radiation) and non-ionizing radiation (daily household appliance radiation). At present, it has not been proved that non-ionizing radiation is harmful, and the harm of ionizing radiation depends on dose;
4. The radiation that the scanner gets for a lifetime may not be as harmful as smoking a pack of cigarettes.
Is the light emitted by the scanner harmful to the eyes?
It must be harmful,
That kind of laser, infrared ultraviolet rays and the like are very irritating to the eyes.
Harmless.
Common scanners have two kinds of light, one is light-emitting diode, and the other is laser.
Light-emitting diode (LED) is a kind of semiconductor light source, which is widely used in electronic equipment, such as indicator lights, signal lights, display screens and so on. Harmless to human body.
Laser scanner uses laser, but the power is very small, which is harmless to human body, but it should avoid direct contact with eyes.
There is also a relatively rare infrared scanner, which uses infrared rays and is also safe for the human body.
Is the scanner harmful to human eyes?
Harmful ~ Don't look at the light emitted by the scanner with naked eyes. I don't know why, but the first page of the scanner manual I bought says. Cover when scanning things.
Is being scanned by a scanner harmful to your eyes?
Scanners generally use cold cathode tubes, which have high brightness, no radiation and will not cause harm to human body. Please feel free to use them. It's like a high-brightness fluorescent lamp. If there is any harm, don't stare at the light all the time, otherwise it will do harm to your eyes.
