What is radiation? What are the hazards of radiation?

Radiation:By electromagnetic or mechanical waves, or a large number of microparticles (such as protons, alpha particles) from the emitter, the process of propagation in all directions in space or medium, can also refer to fluctuations in energy or a large number of microparticles themselves.

People who work, study, and live in environments where radiation sources are concentrated are prone to insomnia, memory loss, weakness, and low immunity, and their cancer cells grow twenty-four times faster than normal.

How far is radiation from us In our living environment, radiation is everywhere! Household appliances: television, refrigerator, air conditioning, microwave ovens, vacuum cleaners, computers, etc. Office equipment: cell phones, computers, photocopiers, electronic instruments, medical equipment, etc. Home decoration: marble, composite flooring, wallpaper, paint, etc. Surrounding environment: high-voltage lines, power substations, television (radio) signal towers, etc. The natural environment: sunspots, etc. A healthy person can withstand a brief 5000R load, but only 700R dose is enough to make a person's life easier. A healthy person can withstand a brief load of 5000R, but a dose of 700R is enough to make a healthy person suffer a fatal threat, but each person's body resistance is different, and each person will experience different degrees of symptoms. Generally, exposure to electromagnetic radiation can cause headaches, insomnia, irregular heart rate and other central nervous system problems. At the same time, for some people's eyes may have an impact, vision loss, skin diseases and other phenomena, heavy and may cause cancer. For pregnant women, it may lead to miscarriage, and elderly people with cardiac pacemakers should be especially careful. At the same time, different people or the same person at different ages on the tolerance of electromagnetic radiation is not the same, even in the excessive environment, does not mean that all people will get sick, so there is no need to electromagnetic radiation "grass". However, the elderly, children, pregnant women or patients with pacemakers, sensitive to electromagnetic radiation and long-term work in the environment of excessive doses of electromagnetic radiation should take precautionary measures.

Harm to pregnant women

Life has a lot of electromagnetic radiation, such as: "microwave ovens can not be used more", "can not use the computer during pregnancy", if you are a mother-to-be, you need to be more concerned about this issue. It is not enough to provide sufficient nutrition for the growth and development of the fetus, but you should also stay away from all the negative factors that may cause to the fetus, such as: electromagnetic radiation. Electromagnetic radiation affects the human body to varying degrees, and is usually most sensitive to women and children. Pregnant women and fetuses are especially vulnerable. In the case of the embryo, electromagnetic radiation prevents early cell division or even causes cell death, and also prevents the normal development of the placenta. Science has shown that, in conjunction with the development of the fetus, the risk is much greater in the first 3 months of pregnancy than in the middle or late stages of pregnancy. Specifically, 1-3 months for the embryonic period, subjected to strong electromagnetic radiation may lead to miscarriage, may also cause fetal limb defects or deformities; 4-5 months for the fetus forming period, electromagnetic radiation may damage the central nervous system, leading to infant mental retardation; 6-10 months for the fetal growth period. The main consequence of this is low immune function, weak body after birth, poor resistance.
