Is there a lot of radiation from laser machines? What is the harm to the human body for a long time to the laser?

According to relevant experts, there are six main aspects of its harm. \x0d\ One of the hazards\x0d\\\x0d\\\x0d\it is very likely to be one of the causes of leukemia in children. Medical research has proved that prolonged exposure to high electromagnetic radiation can cause changes in blood, lymph fluid and cellular protoplasm. Italian experts have researched and concluded that more than 400 children in that country suffer from leukemia every year, and that the main reason for this is that they are too close to high-voltage lines and are thus exposed to severe electromagnetic pollution. \x0d\\\x0d\\ hazardous second \x0d\\\x0d\\ capable of inducing cancer and accelerating the proliferation of cancer cells in the human body. Electromagnetic radiation pollution can affect the human circulatory system, immunity, reproduction and metabolic functions, and in serious cases can also induce cancer and will accelerate the proliferation of cancer cells in the human body. Research data from Switzerland pointed out that residents of households surrounded by high voltage lines passing by are 7.4 times more likely to suffer from breast cancer than normal people. \x0d\\\\\x0d\\\The American Cancer Medical Foundation of Texas for some patients who suffered electromagnetic radiation damage to a sample of laboratory results show that in the high-voltage lines near the work of the workers, the growth rate of their cancer cells than the general population to be 24 times faster. \x0d\\\\x0d\\ harm of the third \x0d\\\\x0d\\ affects the human reproductive system, mainly manifested in the lowering of sperm quality in men, the occurrence of spontaneous abortions in pregnant women and fetal malformation. \x0d\\\x0d\ harm of the fourth \x0d\\x0d\ can lead to children's intellectual disability. According to the latest survey, China's annual birth of 20 million children, 350,000 for defective children, of which 250,000 for intellectual disability, some experts believe that electromagnetic radiation is also one of the factors affecting. The World Health Organization believes that electromagnetic radiation from computers, televisions and cell phones has an adverse effect on the fetus. \x0d\\\x0d\ harm of the fifth \x0d\\x0d\ affects people's cardiovascular system, manifested as palpitations, insomnia, some women's menstrual disorders, bradycardia, reduction in the volume of heartbeat blood, sinus irregularities, leukopenia, decreased immune function. If patients with pacemakers are exposed to high-voltage electromagnetic radiation, it will affect the normal use of the pacemaker. \x0d\\\x0d\\ harm of the sixth \x0d\\\x0d\\ on people's visual system has adverse effects. As the eyes belong to the human body to electromagnetic radiation sensitive organs, too high electromagnetic radiation pollution will cause vision loss, cataracts and so on. High doses of electromagnetic radiation will also affect and destroy the body's original bioelectric current and bio-magnetic field, so that the original electromagnetic field in the human body abnormal. It is worth noting that different people or the same person at different ages on the ability to withstand electromagnetic radiation is not the same, the elderly, children, pregnant women belong to the sensitive population of electromagnetic radiation.
