Laser was originally developed from abroad. According to the transliteration, it was called laser and other names. It was changed to laser by the famous Chinese scientist Qian Xuesen in the early 1960s. As the name suggests, laser is the light that is emitted when stimulated. Can radiate. It reminds me of the laser weapons in Star Wars, so since it is the energy generated by excitation, there must be radiation, but it depends on what industry it is in. For example: the ones used in the military mainly use radiation to attack; but the lasers used in medicine mainly use energy to treat diseases, so the laser equipment used in industry and the equipment needed in medicine They are the same. They are all low-power equipment required for production. They will not cause large radiation and can be used with confidence. However, in long-term use, it will still cause some small injuries, such as: cutting machines, because the power is completely larger than marking machines and welding machines, so in order to minimize the laser radiation, some small protective measures can be taken .
The eyes are the most harmed by laser equipment to the human body. Because the eyes are the most vulnerable part of the human body and have special functions, some discomfort may occur when looking at the light source for a long time, so try to match a Eye protection such as sunglasses. In this way, the wavelength of the light source generated by the laser equipment during operation and the light source that appears during product processing can be filtered and reflected to achieve a protective effect. This is also a method that is currently widely used in industry. The human body will be exposed to some radiation under normal circumstances, and in addition to the inevitable radiation from laser equipment, you can eat some vegetables or animal livers containing vitamins in your daily diet to supplement enough health to help you function perfectly. Complete quality tasks.
