With the development of science and technology, radiation is not very fresh to people, because radiation is ubiquitous, and the electrical appliances that we often use in daily life have a lot of radiation, such as computers, mobile phones, hair dryers, photocopiers, etc. With a lot of radiation. Radiation is strong and weak, and proper self-protection measures can reduce the harm that radiation brings to us. Today I want to introduce the radiation of the laser cutting machine for us. As we all know that the radiation from the laser cutting machine cannot be underestimated, especially it can cause fatal damage for human eyes. So how should we protect yourself from the radiation damage of the laser cutting machine? Next, we will explain it from several parts of the human body.


一.The eye 

Generally, if you firstly contact laser cutting machine who will prefer to stare at the cutting head. If you look at the spark generated by cutting for a long time, it will hurt your eyes and have a tingling sensation. The characteristics of the laser emitted by the laser cutting machine during processing can make the energy highly concentrated in space and time. Focusing on the retina to form an image through the refractive medium of the eye, the energy density on the retina is increased by 104-105 compared with the incident energy density on the cornea; the laser monochromaticity is good, and the color difference in the fundus is small. Induction of very low laser energy can cause damage to the cornea or retina.


二.The skin 

When the laser shines on the skin, if the laser power is too large, it can cause skin damage. Of course, the damage can be repaired by the tissue. Although its function will be reduced, it does not affect the overall functional structure. If it is irradiated for a long time, it may burn and stay. Although the damage to the eyes is much lighter, it must also be highly valued.


二.The breathe


The high temperature generated by the laser cooperates with the gas to complete various processing, and at the same time, a large amount of dust is generated. Especially when processing some special metal materials, the generated smoke contains a lot of chemical components, and the dust is suspended in the air. All this are harmful to our human body.


How to avoid the damage caused by fiber laser cutting machine?


1.It is necessary to have laser cutting machine protection equipment and wear protective glasses to prevent laser damage to the human eye. Especially, when the fiber laser cutting machine is working, we can’t look directly at the laser in the work area.

2.It is suggested that operators should pay attention to eat more carrots, bean sprouts, tomatoes, lean meat, animal liver and other foods rich in vitamins AC and protein, often drink some green tea, etc., because these foods can help humans better maintain their eyes and allows the human body to better maintain the human body under the conditions of laser cutting machine radiation.

3.It is necessary to have a matching dust removal device, try to operate in a smooth air environment, and wear a mask as much as possible.

4.It is best to paint the walls and walls of the work environment to darken to reduce radiation when arranging the cutting site.

5.It is best not to touch the finished part immediately to avoid residual burns.
