What are the hazards of radiation to the body

Our lives are filled with chemical substances everywhere, many of which are chemically radioactive and can cause great harm to our skin. Over time, we will develop various skin diseases. I believe that everyone does not know much about the harm of radiation to the body. It is very necessary to understand it in advance. Let’s briefly describe the harm of radiation to the body.

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 deformities, 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 sievert Can cause changes in the blood, but no serious damage 0.50-1.0 sievert Changes in blood cells and some damage, but no fatigue 1.0-2.0 sievert There is damage, and the body may feel weak 2.0-4.0 sievert There is damage, general weakness, and the weak may die 4.0 sievert 50% fatal injury 6.0 sievert and above may cause death Radiation around us When it comes to 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 comes from two sources: one is radiation in the form of high-energy particles, which comes from outer space and is collectively called cosmic rays; the other source is natural radioactivity, which is radioactive radiation that naturally exists 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.

We must prevent our bodies from radioactive substances, reduce the harm of radiation to the body, and avoid causing great harm to our bodies due to long-term skin exposure. We can apply some skin care products to effectively alleviate this situation. At the same time, we can wear some anti-radiation clothing to achieve good therapeutic effects.
