In fact, the existence of radiation is a delayed phenomenon, and human beings have been exposed to natural radiation environment since birth. Planets such as the sun also constantly produce electromagnetic radiation from outer space, which is harmless to human body. With the development of modern workplace environment and medicine, more and more artificial radiation poses a threat to human health. Of course, these hazards will also affect expectant mothers and babies.
At present, the medical community is still controversial about the lethality of electromagnetic radiation, but as long as the products containing artificial radiation are not used excessively, the harm of electromagnetic radiation to health is minimal. Mothers need not be too nervous. In line with the principle of reducing the time of using products with artificial radiation and keeping a safe distance, you will definitely make yourself and your baby healthy and safe!
Where is the radiation?
Analysis of electromagnetic radiation
In our daily life, radiation can be divided into two types:
1. Natural radiation. This refers to the radiation naturally existing in human living environment. Including cosmic rays, radiation from the surface, radiation in the human body, etc. Some of this radiation comes from the sun and other planets, and our bodies themselves emit radiation. Natural radiation is harmless to health.
2. Artificial radiation. This is the radiation produced by human living environment, such as computer radiation, mobile phone radiation, household appliances radiation, medical radiation, medical radiation and so on. While enjoying the convenience brought by electromagnetic radiation, human beings are constantly following its negative effects.
In China, the natural radiation dose accounts for 8 1.2% of the mid-life radiation dose, and the artificial radiation dose accounts for 18.8%. So unless it is influenced by personal living environment and eating habits, or through long-term contact with some industrial environment or medical treatment, there is no need to worry about electromagnetic radiation in general life. However, pregnant women and babies are more vulnerable to the influence and infringement of the external environment because the internal environment is changing or in the stage of growth and development. Therefore, it is beneficial and harmless to master some knowledge of radiation protection in daily life.
The harm of computer radiation
Six crimes of electromagnetic radiation
If exposed to ultra-strong electromagnetic radiation for a long time, the following symptoms may occur:
1. skin aging is accelerated.
2. The incidence of various malignant tumors has increased.
3. The decrease of sperm activity and quantity leads to infertility.
4. The embryo develops well, the abortion rate of pregnant women increases, and the incidence of teratoma increases.
5. Decreased resistance and slow growth.
6. There are neurasthenia symptoms such as headache, insomnia and arrhythmia.
Radiation protection strategy for pregnant women
The pollution of radiation environment is everywhere. For expectant mothers, radiation is the enemy that harms the health of mother and baby. Below, let's find out the radiation sources hidden in homes, workplaces and hospitals, and keep a safe distance from them!
Household radiation protection
In recent years, there has been a new term-"radiation house", which has made many families with new fans turn pale. According to radiation detection experts, some of the natural decorative stones used in residential buildings are radioactive, while many building materials such as coal ash bricks and slag bricks made of industrial waste residue are radioactive. Some home decoration wallpaper, wall covering, paint, plastic, plates, etc. A large number of harmful gases are released, which leads to serious indoor air pollution and becomes a "radiation house" and a "polluted house".
Therefore, whether the young couple buy a house or rent a house, they must first do a thorough radiation check to avoid living in an unhealthy environment. If you can't change your residence, you should find the place with the strongest radiation, shield or adjust the position of furniture, which can increase the distance between your family and radioactive substances and reduce the time of receiving radiation.
Radiation protection in the workplace
Computers-There are two kinds of computer radiation.
1. X-ray radiation of computer screen
This can only be avoided by blocking it with a glass fiber, or keeping the distance between the computer screen and the keyboard above 30 cm.
2. Radiation from the electric coil on the back of the computer
This kind of radiation is harmful, but most people don't work behind computers. If there are expectant mothers working in the computer room, pay attention to it and try to avoid working behind the computer. Move the computer in the back to one side, or use a laptop instead.
Mobile phone-the radiation of mobile phone is also a tiny one. Although its efficacy is not as strong as that of microwave oven, it will also cause harm to human body. Therefore, it is best for expectant mothers to reduce the chances of using mobile phones. To make a long story short, try to avoid hanging mobile phones around their waist. At present, there is still a debate about "CDMA mobile phone or GSM mobile phone, which one radiates more". Therefore, no matter what mobile phone the expectant mother uses, she should be as careful as possible!
Copier-coils, electric coils and motors are radioactive, so don't touch or lean against the copier with your body. In general use, the body is 30 cm away from the machine as a safe distance. At present, the newer copiers on the market all install the radiation parts on the chassis, which does little harm to the body.

Safe use of expectant mothers' computers and mobile phones
Pregnant women should not use computers for more than 20 hours a week, and leave every hour 10 minutes.
Pregnant women try to reduce the use of mobile phones.
Pregnant women should also watch less TV, use less electrical products, or try to keep a safe distance.
Medical radiation protection
The influence of X-ray radiation on the fetus is more likely to cause embryonic disability, fetal malformation and brain dysplasia, and increase the probability of children suffering from cancer. But usually in the early stage of pregnancy, exposure to X-rays is more likely to cause major injuries, and the closer to the expected date of delivery, the smaller the impact.
According to Professor Li, a radiologist, if a pregnant woman is exposed to 5 Rey's X-rays, it is equivalent to taking 20 abdominal X-rays or 2 pelvic computed tomography, and the chance of fetal director will increase by 40% in the future.
What if I take an X-ray?
Doctors suggest that unless there is an emergency, women should choose to take X-rays within 10 days after the start of menstruation, so they don't have to worry about taking X-rays after pregnancy.
If pregnant women are exposed to X-ray radiation without knowing it, they should also try their best to keep the filming records so that doctors can help you judge the safety of the fetus. Generally, during pregnancy, if you just take an abdominal X-ray, the exposure will be about 0.5 rays, and the impact on the fetus is not enough to require pregnant women to have an abortion; However, only a small amount of radiation, such as chest X-rays or dental X-rays, has even less impact on the fetus.
Therefore, as long as it is not aimed at high-dose X-ray radiation in or near the abdomen, expectant mothers need not worry too much.
Radiation protection strategy of mother's baby
In the list of key protection targets for prevention, fertile men and women, pregnant women and children are included. Because developing and dividing cells are the most sensitive to radiation. Therefore, all those who are "named" should especially strengthen their awareness of radiation protection!
The baby at home should not stay there for a long time.
1. In front of the computer
Nowadays, more and more computer early education software and children's computer games attract children to sit in front of computers all day. However, experts suggest that children should not spend more than 1 hour in contact with computers every day, and make an appropriate adjustment and rest every 10 minute. In order to avoid computer radiation, parents are advised to buy laptops for their children.
2. Around the microwave oven
Microwave ovens and induction cookers are electrical appliances in the electromagnetic radiation market at home. Pregnant women should avoid using them as much as possible, and their families can do it for them if necessary. Children should not play around the microwave oven.
3. Places with dense wires
There is also radiation in general wires at home. In modern families, the general fixed wires are "hidden wires", which is not a big problem, but if very dense wiring boards or plugs are placed at the bedside or in the most frequent places, it may affect health. Therefore, the bedside should not be equipped with electrical appliances or plugs.
4. In front of the TV
Although there are more and more new TV sets under the banner of "low radiation" and "no harm to eyes", "TV children" who sit in front of the TV for a long time must be unhealthy. Whether from the perspective of radiation protection or education, it is recommended that expectant mothers and mothers let their children watch less TV and keep a safe distance.
