The dangers of computer radiation
We will place potted plants next to the computer to prevent radiation. Pregnant mothers must wear radiation-proof clothes to avoid radiation harming the baby. We also Some people think that CT cannot be done in the hospital because the radiation is relatively large, and some people cannot target radiology staff because it will affect the next generation and cause deformities, etc. These are all people's fears about radiation, so what exactly is radiation? What is the principle? What harm does radiation do to the human body? What kind of things in life are exposed to radiation? How should we protect ourselves from radiation?
The principle of radiation
Radiation itself is one of the In fact, sex words will be used in some literary writings early in the morning. For example, Hu Shi wrote in his "Preface": "I think that animals and plants have no feelings at all. They only have their own mass and force, and their radiation reactions. That's it. In the application of modern high technology, radiation is understood as the phenomenon that part of the electromagnetic energy emitted by the field source escapes from the field source and propagates to a distant place, and then returns to the field source. As long as the temperature is above absolute zero, it is transmitted as electromagnetic waves. This is the way radiation spreads and the basic principle of radiation, and the radiation of certain substances may cause harm to the human body.
Radiation is harmful to the human body.
Radiation mainly comes from nuclear radiation, cosmic radiation, and electromagnetic radiation. We are more exposed to the latter two. Cosmic radiation is mainly radiation from the sun. Electromagnetic radiation is classified from low frequency to high frequency. Mainly: radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays and gamma rays, etc., can be seen in our daily life, so what harm does radiation do to me?
1. Killing cells on a large scale
Cells are actually very mysterious. They are also strong and fragile. As long as they have the right survival conditions, each separated cell can grow and reproduce outside the body and show the characteristics of life. . So cells are the basic functional units of life activities. This is also the strength of cells. However, the fragility of cells is that they have a short cycle and continue to undergo metabolic processes. There are approximately 40 trillion to 60 trillion cells in the human body. However, some household appliances in our homes contain electromagnetic radiation. These electromagnetic radiation fills the space, is colorless, odorless and invisible, and can penetrate many substances, including the human body. If the human body is exposed to a radiation dose that exceeds safety for a long time, Cells will be damaged or killed in a large area. Medical research shows that the incidence of leukemia in this environment is 2.93 times that in a normal environment, and can induce the proliferation of human cancer cells, affect the human reproductive system, and lead to intellectual disability in children. , affects people's cardiovascular system, and has adverse effects on people's visual system
2. It has a greater impact on older pregnant women
Pregnant women are more sensitive to the external environment. Sensitive, especially for older pregnant women, and older mothers still have physiological reproductive disadvantages. Medical research and clinical practice show that the best childbearing age for women is 24-28 years old. This is because women in this period are fully mature, their eggs have the best quality, their pelvic ligaments and muscles have the best elasticity, and their uterus has strong contractility. Women who give birth after the age of 35 are considered advanced mothers, and the quality of their eggs begins to decline. Decline, egg cells are prone to distortion, and various chronic diseases accumulate. Clinical statistics show that the risk of fetal health abnormalities in older mothers is 2 to 3 times higher than that of women of the same age. According to the "Chinese Centers for Disease Control and Prevention and" Peking Union Medical College A hospital survey report shows that electromagnetic radiation caused by microwave ovens, induction cookers, mobile phones, computers, copy machines, etc. is extremely harmful to pregnant women, especially elderly pregnant women. Therefore, doctors advocate that pregnant women, especially elderly women, should pay attention to radiation protection.
Facing radiation correctly
Although radiation is scary, many experts have provided us with many tips to prevent radiation, so we don’t need to be too scary, and radiation is not a strong Carcinogens only affect the incidence of cancer, and many of the harms caused by radiation can be treated.
Principles of plant radiation protection
Because the seriousness of radiation harm to human body is recognized, plants are also divided into ornamental plants and radiation-proof plants. It is worth noting that many plants have ornamental properties. However, radiation-proof plants and some plants can absorb harmful gases through photosynthesis, easily absorb and resolve electromagnetic field radiation toxins in the surrounding environment, reduce indoor and outdoor pollution, and are beneficial to the human body. Healthy, for example, cruciferous vegetables have the function of protecting against radiation. This research result has obtained a national patent. Furthermore, the stomata on the cactus flesh will close during the day and open at night, so they will absorb carbon dioxide and release oxygen at night. , so it has the function of increasing fresh air and negative ions, and also has a good inhibitory effect on bacteria in the air.
Radiation awareness
Radiation awareness requires us to have the awareness of radiation protection. We cannot just stay in the fear stage, but must have a comprehensive understanding of radiation and understand its principles. and hazards, based on popular science and medical knowledge, effective prevention is carried out to minimize harm.
Radiation is like sunlight and we live with it day and night. Although many advanced technologies have brought us a lot of good news, we cannot ignore the negative effects they bring, that is, radiation threats, so we must use High technology and at the same time take protective measures against radiation.
