One, X-ray examination of the human body has damage, the more rays shine, the greater the risk of cancer, this radiation can penetrate the cells, damage DNA, and even induce some cancer cells. x-ray will destroy the internal structure of the cell, the genetic molecules of the life-long damage that is difficult to repair. X-rays destroy red blood cells and may induce blood disorders such as leukemia. It is recommended that pregnant women should avoid such tests as much as possible, especially in the first trimester of pregnancy. Because this is a critical period for the formation of important fetal organs, X-rays may cause mutations in these cells and tissues that have not yet developed and finalized, and the incidence of congenital malformations in the fetus will increase. In addition to pregnant women, children are also one of the high-risk groups for radiation damage. From the radiobiological theory analysis, the radiation sensitivity of a tissue is directly proportional to the cell division activity, children are at the peak of growth and development, active cell division, more sensitive than adults, and the younger the more sensitive. If a short period of time to accept a greater number of X-ray irradiation, the harm will be slowly accumulated, resulting in irreparable damage to the body cells, the future of the chances of inducing cancer and other diseases will be greatly increased.
Second, if the affected party is only occasionally exposed to X-rays, then as the medical side of the radiological medical personnel are more likely to be damaged by radiation, although they have taken some protective measures. For example, go farther, hiding behind the door behind the wall, etc., in fact, are futile, the penetration of X-rays is virtually unaffected by brick walls, doors and other objects and weakened, medical radiation is currently the main source of radiation contamination, medical staff due to long contact with rays, high frequency, short distances, they are subjected to the intensity of radiation than the staff of the traditional nuclear industry is also high. Long-term low-dose radiation, the onset of the disease is generally in a few years or even a dozen years later, may occur leukemia, other tumors, aberrations of the fetus, and so on. However, for the hazards of medical radiation, many doctors themselves do not have enough protection awareness, Zhou Gong said there is a sign, if the sweat on your arm hair began to fall off significantly, indicating that radiation has been harmful to the body. About the oral X-ray its main radiation direction is the direction of its trumpet, the rest of the direction is not no radiation, just relatively small, and not the end of the shutter after the radiation stops, the machine will continue to be about 3 seconds of radiation released.
Third, that is not in the face of such a problem we can do nothing about it, no, X-rays are also a kind of electromagnetic waves, but the wavelength is relatively short, penetration ability is relatively strong, the ease of penetration, with the density of the material, the density of the lead plate is very high, so the lead plate can be completely blocked by X-rays, lead plate (Pb) blocking X-rays of the nature of the essence is not a general physical or chemical properties, but the concept of atomic physics, it is the concept of atomic physics, the lead plate (Pb) blocking X-rays is not a general physical or chemical properties, it is the concept of atomic physics, it is the concept of atomic physics. The nature of lead plate (Pb) blocking X-rays is essentially not a general physical or chemical property, but rather a concept of atomic physics, which is the principle of blocking for electromagnetic waves.
