What harm does nuclear radiation do to the human body

With the continuous development of science and technology, many new energy sources or chemical products have brought us great help in life, but at the same time they have also brought us relatively large safety risks, which will to a great extent pose a great threat to our health. So you must be especially careful and attentive in normal times. So what harm does nuclear radiation do to the human body? Let’s talk about it below.

The effect of radiation on the human body begins at the cells. It will accelerate cell death, inhibit the formation of new cells, cause cell deformity, or cause changes in biochemical reactions in the human body. When the radiation dose is low, the human body has a certain ability to repair radiation damage and can repair the above reactions without showing harmful effects or symptoms. However, if the dosage is too high and exceeds the repair capacity of organs or tissues in the human body, it will cause local or systemic lesions. The following table shows the biological effects of radiation currently recognized internationally. From this we can see that the human body can withstand a concentrated exposure of 25 rems without suffering any damage. Of course, everyone's resistance and physique are different. Possible effects of whole-body radiation doses.

0-0.25 sievert No significant damage

0.25-0.50 sieverts can cause changes in the blood, but no serious harm

0.50-1.0 Sv changes and some damage to blood cells, but no fatigue

1.0-2.0 Sv indicates impairment and possible general weakness

2.0-4.0 Xifu: Damage, general weakness, possible death in weak patients

4.0 Xifu 50% critical damage

Above 6.0 Sieverts may lead to death

Radiation around us When talking about radiation, people will be a little scared, because it cannot be seen or touched, but it can cause harm to the human body. In fact, radiation is not a rare thing. It exists everywhere around us. In our daily lives, we are exposed to a certain amount of radiation when we sunbathe, watch TV, wear luminous watches, take airplanes, take X-rays, etc. It’s just that the radiation in daily life is very small and will not cause any harm to the human body, so people can’t feel its presence. A large amount of radiation is very harmful to the human body, so we should take some corresponding protective measures to prevent and reduce the harm of radiation to our body. Natural background radiation Radioactivity is everywhere in nature, and we are always exposed to natural background radiation. The "background" of natural radiation has two sources: one is radiation in the form of high-energy particles, which comes from outer space, collectively known as cosmic rays; the other source is natural radioactivity, that is, radioactive radiation that exists naturally in ordinary matter (such as air, water, soil and rocks, and even food). In addition, people in modern society are also exposed to various man-made radiation, such as X-ray examinations, watching TV, using microwave ovens, etc. The following table lists various background radiations according to their magnitude. From this we can see that humans are exposed to trace amounts of radioactive radiation in everything they eat, use, live in, and travel.

Nuclear radiation is a chemical substance that is extremely harmful to the human body. Generally speaking, if you are exposed to nuclear radiation, your body will be greatly affected. Many people will develop symptoms of physical illness. If the nuclear radiation situation is serious or the infection is exposed to too much nuclear radiation, their lives will be in danger. So you must be especially careful in normal times.
