X-rays are mildly harmful to the human body, but it also depends on personal tolerance. Generally speaking, there should be no harm; in life, you should consciously balance nutrition and eat more vegetables Fruits can help you fight against some diseases.
In order to make a clear diagnosis, clinicians often require patients to go to the radiology department for various examinations, such as fluoroscopy, radiographs, gastrointestinal barium meals, and special imaging. Therefore, we often encounter patients asking radiologists questions of one kind or another. The most common question is: Will these examinations have a big impact on my health? The answer to this question cannot be explained in a simple sentence. The specific situation We must treat it concretely
First of all, we must start with the basic principles of x-rays. X-rays were discovered by German physicist Roentgen Wilhelm Conrad on November 8, 1895. At that time, because people did not understand this kind of ray, they gave it the name of an unknown number "x". Later people called it "x-ray". X-rays are indeed harmful to human health. The greater the amount of X-ray exposure, the greater the damage to the human body. The amount of x-ray exposure can accumulate in the body. Its main harm is that it has a certain lethality to the white blood cells in the human blood, reducing the number of white blood cells in the human blood, which in turn leads to a decline in the body's immune function, making it easy for germs to invade the body and cause disease. According to the theoretical principles of X-ray, the safe exposure dose of patients during X-ray examination should be within 100 roentgens. Based on this exposure dose, the allowable number and time of exposure are determined. For example, the total accumulation of chest fluoroscopy within a few days should not exceed 12 minutes, and gastrointestinal examination should not exceed 10 minutes. As for radiographs, the amount of exposure varies depending on the location, so the corresponding allowable number of exposures is also different. The impact on a patient's health is negligible if he undergoes examinations 2 to 3 times a year. Moreover, with the continuous development of medical imaging, films and cassette holders currently use "green-sensitive screens" and "green-sensitive films", so that the amount of x-ray exposure is reduced by 1/2 of the original dose, thus providing greater protection. It improves the patient's health without compromising the diagnostic effect at all. In addition, in recent years, major hospitals have adopted the method of photography as the main method and fluoroscopy as a supplement. On the one hand, it is to reduce the patient’s excessive intake of X-rays (the amount of fluoroscopy is larger than that of X-rays), and on the other hand, it can also provide a basis for diagnosing diseases to facilitate treatment, review and comparison.
Although X-ray examination is safe for most people, it should be emphasized that since fetuses, infants, and children are very sensitive to X-rays, pregnant women, infants, and children should avoid X-ray examinations as much as possible. If examination is necessary, especially for pelvic measurement or fetal examination, the number of exposures should not exceed 2 to 3 times. For X-ray examination of infants and young children, it is best to expose only the area being examined and the rest should be covered. Under normal circumstances, it should be relatively safe if the allowable exposure time and frequency are not exceeded. However, everyone’s sensitivity to It's not clear exactly how much exposure there is. However, from a preventive perspective, the fewer x-ray examinations, the better.
It has been more than a hundred years since the discovery of x-rays. As a common medical diagnostic method, it has been used clinically It is widely used, but a considerable number of people do not know that the radiation in X-ray examination can also cause considerable harm to the human body. According to experts, the more X-ray exposure, the greater the risk of cancer. Although the "Measures for the Administration of Health Protection in Radiation Work" issued by the Ministry of Health two years ago clearly stipulates that medical staff should provide necessary protection for subjects. However, in a recent interview, the reporter found that "X-ray examination of patients without any protection" seems to have become a routine, and some hospitals still have illegal operations.
The "Measures for the Administration of Health Protection in Radiation Work" clearly stipulates: "Units engaged in radiological diagnosis and treatment shall formulate quality control implementation plans that are suitable for the diagnosis and treatment projects engaged in by the unit, and abide by the quality Control and monitoring specifications. The protective performance of radiation diagnosis and treatment equipment and the technical indicators related to the quality of exposure should meet the requirements of relevant standards. When diagnosing and treating patients and subjects, the exposure dose should be strictly controlled in accordance with operating procedures. Sensitive organs and tissues adjacent to the irradiated site should be shielded and protected; when pregnant women and young children are subjected to medical exposure, the health effects should be informed in advance.

It is best not to participate in this kind of work for more than three years.
